I was just browsing on the internet, and suddenly my screen went black. I waited less than a minute, and it flashed back on, and a little message on the bottom right of my screen said " Your Nvidia GeForce 8500gt driver crashed, and has been recovered" (I am running Windows 7 Ultimate x86). It worked fine after that until today. I was again, just browsing,...and the screen shut off..but this time it didnt recover. So I powered off the computer and rebooted it, the bios startup displayed fine, as did the windows loading screen, but when the log in screen should have came up, it was just a black screen with several (what appeared to be) dead pixels on the screen. My screen dosen't have dead pixels, this was the card displaying them, and when i moved the mouse..you could see the pointer very faintly behind a bunch of these dead pixels that were following it. I again, shut the comptuer down. I tried restarting again, but this time it wont boot up period. I after all of this noticed that the fan on the Graphics card is NOT spinning, I put one of those PCI fans under the video card temporarily until I can figure out if this card is still good, and then order a new fan. I havent yet been able to get the computer to display anything. It sounds like its booting up (Hard drives are spinning up) but i dont hear any windows sounds. I even pulled the card out and plugged into onboard video...nothing...


Any help would be awesome,
Thanks

Make sure in your BIOS Setup you have only the on board video enabled.
Upon bootup hold the F8 key to boot into safe mode.
Uninstall the Gforce drivers.
Reboot.
Let us know what happens.

If your video cards fan was not spinning, it might be because it requires a seperate power connection from the power supply, check your owners manual.
You most likely fried your graphics card's chip.

The fan has a power plug that goes onto the graphics card chip. It used to spin. THe computer dosent display anything when turned on. It only appears to be running (fans spinning, hard drives spinning) But nothing is displayed,, not even BIOS anymore.

Thanks


Edit: I tried taking out the video card and running hte computer using onboard video..Still wont display anything.
