  To put it in a nut shell, my computer screen is garbled.. In bios/dos boot up area where its running the diagnostics and booting up.. THe screen has uniform white dots across it...   When it gets to the windows loading screen, this turns into groups of blue verticle lines running down the screen vertically.  Then after that it becomes a garbled mess for a instant and the monitor turns off..  I was sweating that it was my video card that broke..  Buuuuttttt if it were my video card I would see these destoritions on eveyrthing.. I do not in safe mode, and by windows booted up from CD..  

  I have uninstalled and installed new drivers.. THough they will not initiate in Safe mode, and I can not reach odviouslly get into regular windows.. I wa sthinking MAYBE it was a refresh rate issue.. This all happened after very commonly I joine da counterstrike  source server on steam.. It was vac protected and I played on that server dozens of times.. What happened is it was on the immediate load screen right to the end, then the screen went black and turned off..  AFter that I was forced to reboot, and basically all of a sudden the garbled effect or possibly artifacts, though it seems to be too uniform to be clear artifacts...

   No my video card wasn't over heating.. Not only is its fan functional and high quality, but it has a 2 fan blower right under it.  At this time this computer is a 3000+ A64 KV8 Pro (abit motherboard) computer, with 2gb of ram, and BFG 6800 GT AGP. 

  I am running the latest version of Windows XP SP 2 at this time.

Did you think about the power supply?????

my knowledge in pc is poor but lately i suffered problems with my pc and that was because my power supply was very weak to support the mother board so check it and let me know if i am right or wrong plz

The fact you are having artifacts during BIOS bootup is very wierd.  Doesn't sound like a driver issue.  Could be a power supply or something wrong with your video card.

Does your motherboard have a video adapter on it?  You could try plugging into that and seeing if you still have these problems.

My suggestions are to pull your vid card out and blow any dust out from the slots. Then re-seat your card into the slot. Then I'd check the cable pins to make sure nothing is bent or touching.

I've had weird video problems before and it was simply that the card got bumped out of place slightly when the video cable got caught up on my desk.

 Just some rough thoughts on top of what the other posters have suggested.

Good luck 

Controller chips can burn out,capicitors can fry,resistors can stop resisting,i think it could be hardware more so than software.I would check for some physical deformities,like black goo leaking from a capicitor or south and north bridge chipsets that look warped.Good luck though.
