Question

I have had an EVGA GeForce 8800 GTS for some time now (a few years I believe), and just recently I've been running into some graphical problems.

Just a few days ago, when booting up, my computer seemed sluggish. When I tried to run any sort of 3D game, I was met with heavy image distortion and almost immediate freezing. The problem only compounded itself with rebooting, eventually leading to discoloration/random bars appearing on the Windows loading screen, and patterened discoloration of my desktop. Eventually it got to the point where it would just BSOD without ever loading windows, and now I get no video at all on bootup.

I'm fairly certain these are all signs of a failing gpu, but I just wanted to confirm with anyone who has any experience on the matter.

Thanks!

EDIT: Yes, I've virus scanned the drive, it's clean. I attribute this to failing hardware over software issues since the drive works fine when removed.

could be a number of causes

what are you running
video card
cpu
m/board
ram
power supply
brand
wattage

check the listings in the bios for voltages and temperatures and post them

get a can of air and blow the computer free of dust pay paticular attention to the fans and h/sinks

check your drives are running in dma mode

I tested the RAM, it works fine. I've tried both outputs on the vid card. Nothing has really changed, it was working fine one day and not the next. The cpu and mobo are fairly new, so I tend to doubt it's them.

I'd post bios temps but I can't get a video feed at all at the moment, which seems to me to further the case for being the vid card, but you're right, it could be any number of things. I'll try swapping out the PSU, see if it makes a difference.

The case is pretty clear of dust, all the fans/heat sinks are pretty clean (I maintain them pretty regularly).

Thanks for the suggestions so far.

Just out of curiosity, what are the "textbook" signs of graphics card failure?

Definitely some heavy artifacting (I didn't really know what that meant until I looked it up :s) so I'm pretty sure I'm spot on with the diagnosis. I'll see if I can get a replacement card.
