Last night I was playing starcraft 2 and my computer froze. When I restarted it my graphics card was not recognized. I can no longer play any games. I took out the card, it had a little dust in it so I cleaned that out, then I formatted the computer and installed the latest drivers. I've still had no luck. When I start the computer I get a black screen with gray dots on it until I get to the desktop. Could my video card be bad? I thought maybe the fan stopped working and it overheated but the fan seems to still be working.
Sounds like your 8800GT is dead. To verify, remove it and connect to your on-board video. Fire up your system and see if it boots. If so, you can use the on-board video until you return/replace the 8800GT.
i'd still check it just to be sure. its about 99.98% chance its the card and .02% chance to be the pcie slot but it'd suck to buy a new card and it doesn't post still ... very unlikely but if you have another machine to check in it'd be worth the 10 min experiment jsut to be sure before getting a new card
