Whats the cause of this problem?


And How do I fix it?|||It sounds like it%26#039;s your motherboard. Try to get into your bios when you boot up. If it won%26#039;t get that far it%26#039;s probably the mobo. You usually don%26#039;t need the hard drive, optical drives, floppy, or ram to get to the bios.





With how old your computer is it will probably be cheapest just to buy a new machine. If the new machine has IDE connections you can probably get info off your old HD; if not you can get one of those external IDE HD to USB adapters (cage?) and connect it.|||Hard drive has failed. Replace hard drive. |||Looks like to me the problem is on the hard drive...try to replace another hard drive.|||Sounds like a bad motherboard, processor, or power supply. Most likely motherboard since there are no beeps on start up. Try switching out the power supply first. You could buy the cheapest pc out there and it would be better than what you currently have.





If it is the motherboard, just buy a new computer. |||Maybe, your computer chip has burned out, but you should make sure that is the problem. My reason is because computer chips are expensive.

Pc clock resetting problem!!?

um, well... my pc clock has been resetting from the time i bought the mobo, which is may 6 of 2006! its been like that for about 2 weeks now... i think its the cmos battery... isnt it? how do i change it? how much is it? is it really that complicated to change a battery? what would happen if i didnt do it right? .... dont rant pls, i just need your answers...thanks!|||look for a battery, approx an inch in diameter, on the motherboard. Use a small screw driver to take out and then bin it after you have made a note of the number on it, eg cr2032.





A nnew onewill cost a couple of quid.





Dont bin it until you have your replacement on to hand.





On the first reboot it will still sulk but once you have set the time it will be happy until the battery dies again.|||Best thing to do is to pop the CMOS battery out and take it to a computer shop so you buy an exact replacement. It should be relatively easy to remove and there is a tab directly next to the battery that can be pressed with a flat head screwdriver.





Make sure you ground yourself on the case or other metal so you don%26#039;t touch the motherboard and kill it with static.

How do I replace CMOS batteries?

When my laptop starts up it beeps and the screen says cmos batteries Does anyone know where they are at and how to change them? I have an IBM thinkpad i series.|||Call up IBM they will replace it for free for you...


If not in warranty period, look for where your cmos battery is located for your model on the net...its most probably located some where near the motherboard, open up the place where it is, you can get a new one for couple of bucks at Radioshack, its is like a button cell...you can replace it at home itself..that will save you lots of time and money..|||You will have to look it up on the internet to find where it is located, but usually you have to get at the motherboard to do so. If there is not a separate little %26quot;door%26quot; you can open, do not try it yourself. Taking apart a laptop is not all that hard if you know what you are doing, but you can easily destroy your laptop if you don%26#039;t. The battery is not even needed for normal operation. It is only used to keep the computer%26#039;s clock accurate if the the regular batter is dead.|||Not sure debby if they are soldier in but I will chek on it and try to get back to yas...*s*

Cmos checksum error-default loaded?

I change the battery on my desktop computer - then went i turn on the computer i got the message ( cmos checksum error - default loaded. This is where it stops and thats it. can anyone help me on how to get my computer running again%26gt; would appreciate it very much. thanks|||You may have to go into System Setup (F2 or Delete usually) to configure your BIOS again. Or it%26#039;s shot, but hopefully the former.|||Okay: From what you say, you%26#039;ve changed the battery and knackered the eprom. I%26#039;m sorry but the only route will be to change the Eprom. The Eprom will be fairly close to that battery and will have a label on with amongst other things the check-sum. This device has gone to that place in the sky. I%26#039;m sorry but its going to be difficult to replace. Look at the label on the device and glean as much as possible. i.e. Chip-set type and the like. It doesn%26#039;t have to have the same check sum, but it has to be the same or very similar chip set......best of luck....ps, that device was/is bespoke to your pc.


Try to run the pc without the battery.......you did%26#039;nt put the battery in the wrong way around did you....did you............

Should I take the battery out when not using my laptop for a long time?

I%26#039;ve searched the Internet a lot for this but most articles are about how to preserve the life of the main battery. I am not using my laptop for several months at a time. Should I keep the main battery in the laptop during this time?


I%26#039;ve been keeping the battery out but then I heard that this causes the laptop%26#039;s CMOS battery to drain faster to preserve the BIOS settings and system time. The CMOS battery is difficult to change in my laptop, a Dell Vostro 1310. So to avoid changing that, is it better to keep the main battery in?


Thanks|||Definitely no.





It goes like this. When you buy your computer, the battery is intact from the manufacturer.





They never did separate the battery from the unit. Because it has no harm effects on your unit.





It%26#039;s not like the Double A batteries that %26quot;leak%26quot; when you didn%26#039;t use for a long time.|||No, i would advise you not to because it can damage. Take it out it might be dusty or something?

Removing the CMOS battery?

Ok I just installed a new video card and a new stick of RAM which is so great


but when i turn on my computer it said


my


CPU clock speed had change or something like that


and I need to change it in MMOS or something


so i ask on other forum it said to take out the CMOS battery


and replace it after 5min.





%26lt;b%26gt;1%26lt;/b%26gt; Ok so last night I found where the battery is but i was wondering how do I take it out? it so hard no matter how much i keep pulling it up it won%26#039;t budge (I%26#039;m not good with computer)





and I search on here about it and i saw a question that said that after they replacing the battery the comp. ask for their password or something like that


i was wondering does this always happen after removing the battery


because i don%26#039;t know my password accept when log in on my profile|||Hi. The term you mean, I think, is BIOS. This is where you control your clock speed and other things. To remove the battery (which may not be necessary!) use a small screwdriver to pry up the end opposite the upper contact. Other wise just hit %26quot;Delete%26quot; when you computer is booting to get in and modify your BIOS settings. Use the defaults.|||replacing the cmos battery. usually ther is a clip like spring that with a small scre driver you can push right on the side and the battery will pop right out. the battery actually sits in side a case and u dont want to pull that off, when u put the new battery in it will just snap in. but by removing the battery it resets all cmos/bios so then at start up u have to go in and reset the bios, ive changed a couple and had no problem in the past but i just changed 1 in my ibm and for the life of me it will not let me change the bios. so im stuck taking it to the shop! oggd luck!!|||okay first after u re-place your battery u will need to probably re-set your bios there is a 3 pin jumper directly over or close to your battery it will say cmos , now after u put in a new battery look at the position of your jumper it should be covering the first 2 pins ( 1 and 2 ) carefully take it off and slip it over pins ( 2 and 3 ) leave it on there for a few seconds then slip it off and put it back over pins 1 and 2 , after u do that u will need to reset your boot sequence and your clock in your bios ( if u have a internet connection u can right click on your time in the task bar click on adjust time and date then click on internet time and click update this will automatically set your time and date ).To get to your bios tap delete while your pc boots up and it will take u too your bios , all bios screens look different but there should be a sub tab that lets u set your boot sequence set your cd or dvd rom ( whichever u have ) to first priority then set your primary hard drive as second and floppy as third ( if u have one ) ,save the changes and if u did it correctly it will reboot to your primary hard drive and then u can set your time threw internet , and go back to your bios and set anything u had set before like if u overclock for instance but i assume if u know how to overclock then u will know how to do this any ways if u dont then your bios will automatically set everythign to default or auto .............Good luck !!

What is Floppy disk(s) fail (40), keyboard error or no keyboard present and CMOS checksum error - defaults ?

I am trying to revive my pentium III computer with asus CUV4X C motherboard. how can i fix this problem. I have tried changing the battery and installed a brand new keyboard but it still doesn%26#039;t work.


What can i do to fix this? Help me please!|||Wow, If you got all of these errors at the same time then something isn%26#039;t right.





But error 40 is floppy disk failure. It means that for some reason the computer can%26#039;t find your 3.5%26quot; floppy drive (usually %26quot;A:%26quot;) or it isn%26#039;t responding correctly when your computer tries to access it during boot-up. This can happen because there is something wrong with your floppy drive, something is causing your computer not to detect it (such as a burned out controller, cable or faulty motherboard), or that you simply don%26#039;t have one. Check your floppy cables and connections first to ensure that they are connected properly, if they are then you may have a burned out controller on your motherboard, a bad floppy cable or drive, or your motherboard may be faulty. If you don%26#039;t have one you can disable the message in your computers BIOS. To get to the BIOS screen, during boot up at the bottom of the screen it will say something like %26quot;press F2 for setup%26quot; or something along those lines. That will take you to the BIOS screen. In the settings there should be options like first boot device, second boot device, and so on... change the one that say 3.5 floppy to something else such as your CD rom (or if you already have one like that just set it to nothing or disable). That will get rid of that message.





Keyboard error or no keyboard present shows up when your computer can%26#039;t find your keyboard or there is something wrong with it. You said you%26#039;ve already bought a new keyboard, so chances are that either you motherboard is faulty or the keyboard controller or port is bad.





CMOS checksum error is usually caused by a dead CMOS battery, but you said your already replaced that... The only other reasons usually are motherboard issues or a virus changed your BIOS settings...





Lets see, we got 3 out of 3. I would say that you have a defective motherboard. (Or a fried one) Make sure when handling a motherboard (or any hardware) to make sure that you are properly grounded because static electricity can kill computer parts, including the motherboard. Also, incorrectly installing a motherboard or the wrong size or type of motherboard can cause a short circuit in some types of cases, especially those that have raised holes. Make sure that you are using plastic or rubber guards when installing a motherboard to prevent this short, and use the correct screws and thier guards to prevent them from shorting the motherboard.





Hope some of this helps,


-Andy|||I have had all these errors before, The floppy disk(s) fail 40 error probably means you need a new floppy drive (Try eBay). With no keyboard present, try a new keyboard, if that fails, it may be a problem with the jack. CMOS checksum error means you need a new CMOS battery. If that does not work, you have either been ripped-off with a dead one, or it is a dud. It also may not be pluged in properly. Hope this helps!

Where can I find, or how can I work out my BIOS settings ( flat CMOS battery)?

I lost my PC BIOS settings. The PC is an AriesPowerXS 6505. By changing PATA to SATA it boots up, most works ok except sound is intermittent, and games such as counterstike crash the pc with horrible graphics problems. (card is ATI Radeon 9550)





Any ideas where to get the full BIOS settings from?|||Most stable CMOS setting is %26quot;Fail-safe defaults%26quot;. Use that as starting point then tweak settings one at a time.


With regard to graphics, update the driver and clean up Windows%26#039; registry.|||do you mean you lost your motherboard%26#039;s CMOS battery? well you can just buy a new one at computer stores. regarding with the sound what problem are you experiencing when you say intermittent? try updating your drivers. and also with your graphics problems, also try updating its driver. if it still crashes, maybe the graphic card itself is defective.

How do I fix BIOS ROM checksum error?

I’m really pissed off by my desktop computer. Damn it!


I can only use it sometimes because it often won’t turn on successfully. I displays an error message:





Award BootBlock Bios v1.0


Copyright © 2000, Award Software, Inc.


BIOS ROM Checksum error


Detecting floppy drive A media…


DISK BOOT FAILUR, INSERT SYSTEM DISK AND PRESS ENTER-





The history of how it’s getting worse is found below followed by the questions.





Eight months ago – My computer turns on normally and shows error message every time I restart it. I have to wait for 10-15 minutes before I can turn it on again after the attempt of restarting it.





Five months ago – The time I have to wait has gotten longer. I have to wait for more than 15 minutes.





Two months ago - My computer does not turn on often. It’s because when I want to turn it on, it always display the error message. But sometimes, I can- but only by luck!





A month ago – I have researched for some treatments. And one of which is changing the CMOS battery, so, I did replace it. But it stays the same. I can hardly turn it on.





Now – I never turned it on again. But I once got into the BIOS Settings then the “CPU External Frequency” was highlighted. The figures were: 133/33(the first on the list)





Now here are my questions:


~ Is the problem hardware or software?


~Does the “CPU External Frequency” have something to do with it?


~I’m planning to reformat my computer ASAP. Will that solve the problem?





Note: My motherboard is ASUS X Series motherboard. (Maybe it would help)





Sorry for that long question and I hope you would help me.


Thanks in advance.|||Below is a quote:





If your computer has just been formatted, your computer might require you to insert the boot CD to be able to run it.





You might hence get the error message Disk Boot Failure- Insert disk and press enter displayed on the screen every time you will try to run it. This might be linked to:


•1. The boot options not correctly set in BIOS


•2. A non bootable CD is found in your CD drive


•3. You do not possess any bootable device


•4. You have installed a new hard disk


•5. The hard disk is not properly plugged


•6. Your system files have been infected


--------------------------------------…


source I got it from:


http://en.kioskea.net/faq/341-error-mess…


--------------------------------------…


My writing now:


So check that your options for boot sequence is right, if you have two or more hard drives installed





Make sure you do not have a non bootable cd in the drive, if set up for CD start first. It should be set up to start on Hard drive, then CD





Make sure you do not have a non bootable floppy disk in the floppy disk drive





Check all your connections, maybe one of them is loose. (Cables and power to hard drive)|||Looks like either the Master Boot Record was corrupted, or the hard disk has failed.





Given what has been happening over the months, it sounds like your hard disk has failed. IF that is the case, you will need a new hard drive.

My computer runs very slow and its clock is behind?

My computer runs very slow and its clock is behind?


Hi all Just a few days ago I sent a question here asking how I could get a free software antivirus to replace one(McAfee) I had on my computer(Dell Inspiron 1501 Windows Vista) before which was about to expire. I installed both Avast Home Edition and PC tools Firewall on my computer. But my computer started running slower than before and although I have made all I know to set its clock on time now after a week it is already 2 minutes behind the actual time. What is the purpose of an antivirus/firewall software if it makes you computer run at snail%26#039;s pace every time you tun your computer on? Even while I am typing this text at times the pointer disappears and I can%26#039;t not longer see the chararacters on the screen. When I click on an item( weblink a window or icon) it takes a long time for the action to be performed. As for the clock I have tried almost everything I was told to: I have sent the computer back to Dell and they changed the CMOS battery, after I spent hours on the phone with their skillfull and kind technicians to fix that problem I have connected to a time server, I have set manually my computer on time from the toolbar etc. Still, the computer runs behind everytime I switch it off and turn it on later. In response to my previous question someone told me I might be infected by a malware, but how could I know which one it is and get rid of that without having to format my hard disk. Many thanks to all beforehand|||Everyone knows that Windows computers can sometimes slow down over time. While not an exhaustive list of solutions to problems, this collection presents some ways to speed up a computer.





1. De-Fragmenting


Over time, the data on your hard drive gets scattered. Defragmenting your hard drive puts your data back into sequential order, making it easier for Windows to access it. As a result, the performance of your computer will improve.


a) Right click of C Disk.


b) Click properties.


c) Click tools tab.


d) Click %26quot;Defragment now%26quot;.


e) Click Defragment.





2. Uninstall Unneeded Programs


Removing programs that you no longer use can free up space on your computer and speed up your system%26#039;s performance. However, you need to uninstall the programs properly to see much improvement; deleting them is not enough.





3. Stop Programs from starting on Windows boot


One way you can speed up your computer is to prevent programs from launching themselves at start-up. Not only do the unwanted programs delay the start of Windows, they also continue to slow down your computer since they use system resources.


a) Open your Start menu.


b) Click Run


c) In the command screen type %26quot;msconfig.exe%26quot;


d) In the %26quot;system configuration utility%26quot;, click either %26quot;service%26quot; or %26quot;startup%26quot; tab


e) Uncheck all programs that you are no longer using.


f) Click %26quot;OK%26quot;





4. Check for Spyware and Adware


Spyware is software that allows companies to monitor what websites you visit or even access your computer. Adware is software that displays advertisements. Both use system resources and slow your computer down. Detecting and removing the programs will improve system performance.

5. Clean your Registry


Microsoft Registry Problems = Slow Computer!

They should not slow it down to where it stops. Because the computer does not keep good time signals it is working overtime doing something. I would download spybot search and destroy to check for viruses. I would also defrag the hard drive.

The clock of my laptop is behind actual time?

Hi all,


I have been experiencing that issue for a long time now. I bought my computer( a Dell Inspiron 1501 with Windows Vista as Operating System) a bit more than a year ago. I called the Dell Support Team several times and through the phone I followed all the instructions I was being told, but the problem remained. Since my laptop was still under guarantee I sent it back to Dell and they changed the CMOS battery and allegedly made all the necessary verifications according to the checklist they sent me back along with the laptop. Still, after that I encountered the same issue. I called once more and they fixed the problem. Everything went well for a few days as usual. But thereafter theproblem occured again until now. I am tired to call Dell and spent lenghty minutes on my cell phone for the same issue. Can someone tell me how to fix that once and for all?


P.S My laptop clock is behind for about 14 minutes. The CMOs has been changed|||hmmm maybe you could %26#039;adjust time/date settings%26#039; in the toolbar? have you tried that before?|||Your PC is infected with malware, and this is EXACTLY what is changing you clock settings.





TIP: Do a Vista Recovery, as explained in the Dell User Manual. It will 100% cure the problem, until the next time your PC gets infected. BTW, I%26#039;ll bet Dell tech support told you this already!!!|||Look for free atomic clock sites and chose one that gives you the choice to update automatically your system clock, for example, whenever you go on the web. There is such one but cannot remember the site to tell you now. There other atomic clock sites that connect automatically when you go on the web and you simply have to click %26quot;update%26quot; manually.


[PS: you do not say how long it takes for your system clock to lose 14 mins]|||I know this has nothing to do with it but dell aint the best company to deal with on some issues

How can I fix my computer?(won't boot past the Post screen & can't access BIOS)?

OKAY.. I think this Question is DETAILED enough..since my last one wasn%26#039;t. if you don%26#039;t wanna read all this..there is a very fast explanation on the very bottom of this %26quot;novel%26quot; titled %26quot;Short and to the Point%26quot;.





PC Story/symptoms:





I was getting the %26quot;nvlddmkm%26quot; error along with the %26quot;Display adapter crash%26quot; error a few days ago. I called the manufacturer of my Graphics card and they sent me an e-mail along with trouble shooting remedies. I tried all the remedies they sent me and nothing seemed to work. So i took out my Graphics card and thats when i ran into problems.My PC will now not boot correctly. Can%26#039;t enter BIOS or Safe modes. It is not due to a virus either(already ruled that out). I am open to any other advice/input now..thank GOD I saved and backed up all my files b4 this all happened. I am so ready to just throw this PC away.

Note:


I HAVE ALREADY CHANGED THE CMOS BATTERY AND IT DIDN%26#039;T SOLVE THE PROBLEM...


ALSO I HAVE UPDATED THE BIOS FROM THE DELL SUPPORT PAGE AND ALSO DIDN%26#039;T FIX IT.





Please help|||This IS a CMOS problem. The fact that you state you%26#039;ve already replaced your CMOS battery means that the overheating issues have likely permanently damaged your CMOS chip. Unfortunately your only solution would be to replace the CMOS, something most motherboards (and certainly laptops) don%26#039;t allow. Seek a warranty replacement from Dell immediately.

How to disable the bootup password without removing the cmos battery?

i tried to change the password for a pc. but unknowingly something happened with the bootup password. Its not entering the bios also. Without opening the system how can i change or remove the password for tat?|||If the problem is that you dont know the password your only solution is to power down the pc, uplug from the wall, hit the power button once to discharge the built up power in the power supply and then open the case and remove the cmos battery. let it sit for maybe 15 minutes or so and put the battery back in and start the machine back up. at this point your bios settings will be set to the manufactures defaults. either you can run with those if it is a newer machine, if not you will probably have to go into the bios and reconfigure.





If you have the boot password then its as simple as entering the bios and disabling the setting that specifies using the password to begin with.|||it has to enter bios. maybe your delete key is broken.|||At start up, see who the BIOS manufacturer is. Google manufacturer default BIOS passwords. There are some that will allow you into the BIOS, it depends on how old your system is.

Hi ppl, please help me with my laptop clocking problem that change very frequently after every time I made a clock correction. It happens before the I Shut down the laptop.





So I am thinking of replacing the CM OS battery. Could anyone send me a complete link that illustrate the methods/procedures on how to change the CMOS battery.|||Obtain battery information





Unfortunately, most manufacturers will not list the exact type and model of your CMOS battery; therefore, once you have located the battery, write down all information about the battery (Voltage, chemistry, wiring, and packaging). If possible, remove the battery and take it to the location you plan on purchasing a new battery from.











Removing the battery





Caution: While in the computer make sure you%26#039;re aware of Electro Static Discharge (ESD), your computer is off, and that you%26#039;re properly grounding yourself. Especially before removing the battery.





If you%26#039;re computer is using a coin cell battery similar to the above example picture. Removing the battery is relatively simple. Simply use your fingers to grab on the edge of the battery and pull it up and out of the container holding it. Some motherboards have a clip holding the battery down. If your computer has this clip you may need to use one had to move the clip up and the other hand to pull the battery out.





Unfortunately, not all CMOS batteries are removable; some manufactures will only allow a replacement battery to be added. If you%26#039;re not using a coin cell battery and are not able to determine how to remove it refer to your motherboard or computer documentation and/or contact your computer manufacturer for additional assistance in removing the battery or how to insert a new replacement battery.





Users with computers that do not have removable batteries only options to install a new battery will most likely also need to set a jumper when adding the new battery into their computer.





Insert the new battery





Once you have purchased a new battery, remove the old battery (as instructed above) and replace it with the new battery.





Enter CMOS values





Once the battery is replaced turn on the computer and enter all values back into CMOS or set the values back to the default settings. Additional information about getting the values back to default can be found on document CH000970.





After the values have all been entered make sure to save the settings before exiting. Many CMOS setups allow you to press a key (such as F10) to save values and exit all in one action.





If after following all the above steps you continue to experience the same error when your computer starts and/or your computer is still unable to keep the stored values it%26#039;s likely that you%26#039;re experiencing a more serious issues. Most likely causes are bad power supply or bad motherboard.

Sometimes in my PC, Windows is loaded after 10-15 mins of CPU startup....n sometimes it does not get loaded at all.... Can CMOS battery be d culprit for dat??? its one year old...|||Contrary to the others who have answered, the CMOS battery CAN have an indirect relationship with the boot process. It not only is responsible for keeping the RTC (Real Time Clock) updated and current, but it also is what keep the BIOS from losing it%26#039;s information. On many (especially older) motherboards, certain timing settings that the BIOS has %26quot;learned%26quot; from previous boots are stored, and helps speed the boot time; this is known as %26quot;Quick Boot%26quot; (no, Quick Book is not merely bypassing some tests).





If the CMOS battery is dying, it could cause the BIOS to dump these stored settings. Additionally, the RTC works with the CPU clock on some processors for timing purposes (although this is much less common now).





A completely dead CMOS battery CAN prevent proper POSTing, especially if the dead battery begins to draw power (sponge effect).|||cmos battery does a few simple things like the time of the pc, it has nothing to do with the opearting system, could be a virus


i think this virus is called virut.q and it infects the startup files and low level sectors in the harddrive, to cure this you wil need specialist help


go to http://www.cablemodz.com and post your problem there, they should help you straight away|||That should not be causing your problem considering your it is only one year old. The battery should last six to eight years. There is something else wrong seems like you have registry and startup files corrupted try to do a virus scan and registry clean up. Otherwise you can try the system restore to a previous date and if all else fails re-install windows. If windows does not load try to hit F8 during start up to go into safe mode and see if you can clean up your computer there. Good luck.|||A symptom of a dead CMOS battery is when your computer can no longer keep time. Another symptom is when your BIOS settings fail to persist (keep resetting to defaults), however most newer BIOSes aren%26#039;t affected by this since they store settings in non-volatile flash memory.





The boot process doesn%26#039;t depend on the CMOS battery.
