video card not detected

October 2, 2009 at 11:04:58
Specs: Windows XP, core 2 duo 2.66 GHz, intel desktop board DG33BU, 2GB 800Mhz ddr2 ram, 250 gb hardisk
I have a problem with my NVidia 8600 GT video card, the video card is not detected by my pc, when booted a blank screen appears ( not even the bios splash screen is displayed)

After working fine for 2 years with no problems, my card NVidia 8600 GT suddenly failed to get detected from past 2 days.

This happened After using windows hibernate feature for first time, i tried to boot my pc the next day and my pc booted with a blank screen.

Things that i have tried so far :-

I have tested my NVidia 8600 GT and Monitor on another pc and it works absolutely fine.

I even upgraded the PSU and it did not help.

updated the bios to the latest version.

BTW - The pc boots normally when the monitor is connected to the onBoard VGA graphics device.

any Help?

Appears to be a socket or motherboard problem.
Very unusual.

Thanks for the reply

The fan on board the video card is running, so power is reaching the card.

I have noticed something in device manager under "System Devices" the device "Intel(R) G33/G31/P35/P31 Express Chipset PCI Express Root Port - 29C1", which is i suppose related to PCI-E slot is active and working properly , and there is a new "Default monitor" device displayed under "Monitor" in device manager in addition to the monitor that i'm currently using.

There was only one monitor listed in device manager before video card detection failed, don't know what it means, but it might help to find out, what exactly is the problem

"when booted a blank screen appears ( not even the bios splash screen is displayed)"

That eliminates the possibility of a windows problem.

does it mean that card is not detected at bios itself?

There is an option called "PEG Negotiated Width" in bios (cant be changed) which says "Not Detected" when the video card is removed from slot, but when inserted in slot and in bios if "Primary Video" is set to PEG then "PEG Negotiated Width" changes to 0

so, it means that card is being detected by bios, right? or partially at least?
