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!
