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.





PS%26gt; I have attached photos also..have a looky-loo...and THX in advance for your time/patience/understanding/prayers/crit鈥?etc..

Remedies I have tried with Nvidia Card installed but didn%26#039;t work either are:

-Installed the Nvidia Graphics card correctly.


-Connected VGA/Display cable to Graphic card port..which is also connected to Monitor.


-Turned on PC.


-Green light was on in front of pc.


-PC screen now filled with weird-fuzzy-patterns(see pic for details):

-Tried to reset CMOS/Battery again.


-Turned on PC.


-Nothing changed..still see those patterns on the screen.

ASUS install at boot up= FAILED..post screen stuck-blah blah blah


Changed battery(again)= FAILED

What do I do to fix this(may want to read what I have already tried area of this question)?|||Remove any plugin cards you don%26#039;t need to boot such as a network card. Reseat everything such as power supply connections, drive connections, and your RAM modules. Now, try booting again and use your %26quot;old%26quot; keyboard.
