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't. if you don't wanna read all this..there is a very fast explanation on the very bottom of this ';novel'; titled ';Short and to the Point';.



PC Story/symptoms:



I was getting the ';nvlddmkm'; error along with the ';Display adapter crash'; 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'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?etc..

Trouble shooting methods I have tried but have failed are:(without Nvidia Graphics card Graphics card installed);



-Made sure power to my house was on..bill was paid and current.

-Made sure I am capable of reading and writing in English.

-Removed Nvidia Graphic Card from CPU case aka uninstalled.

-Made sure all my cables/wires are plugged in properly and in their correct ports,yes,even the -Monitor is installed correctly.

-Made sure RAM cards were in and secure.



-Turned on Power to my PC:

-Checked fans are running properly(even dusted them correctly before I started the pc)

-Turned off PC.

-Took out Battery for 10-15 minutes(battery is not old or defective)

-Delete/Tab keys still don't work, can not enter BIOS.



Remedies I have tried with Nvidia Card installed but didn't work either are:

-Made sure PC's power was off.

-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):

-Turned off PC.

-Tried to reset CMOS/Battery again.

-Turned on PC.

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



Other things I have tried:

Reinstalling Vista at boot up= FAILED. Screen stays stuck on Post screen and goes no further won't access any CD's or other media.

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

Changed battery(again)= FAILED

***See the pattern yet?

What do I do to fix this(may want to read what I have already tried area of this question)?How can I fix my computer?(won't boot past the Post screen %26amp; can't access BIOS)?
Remove any plugin cards you don'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 ';old'; keyboard.
