Video Card Not Detected

April 20, 2010 at 00:08:31
Specs: Windows XP
The hardware in question are:
ASUS M4A785T-M/CSM motherboard
EVGA Nvidia Geforce GTS250

I've installed Windows XP sp3 and updated all the drivers for the motherboard itself. The device manager only shows the ATI RADEON 4200 or whatever onboard graphics the motherboard has.

I've tried installing the drivers for the video card from the support CD and from the driver downloaded directly from I've checked my motherboard's BIOs -- made sure the date is correct and that the primary video support (I think this is how it's worded in the BIOs screen?) is the PCI slot that the graphics card is in.

I've tried disabling the onboard graphics through the device manager and through the BIOs at startup.

None of these things have worked. Are there any other strategies I ought to try?

1. Un-install onboard video driver
2. Go to bios & disable onboard video, return shared memory, set initial display to pci-e then save and exit.
3. Install v-card, then install v-card driver. Don't install v-card driver in safe mode.
Oh and make sure the monitor cable is connected to the card.

edit: it's PCI XPRESS not PCI.

Thank you very much for your prompt and helpful reply. I just have one question. What do you mean by 'return shared memory'? Are there any synonyms or keywords I should be looking for while navigating the BIOs that'll point me to this? I'm not sure what it means.

Shared memory used by igp, you need to return it to the memory. If u can't find it disable onboard video.
