Computer stopped detecting graphics/video card entirely

June 6, 2012 at 10:21:18
Specs: Windows 7
I was gaming on my laptop yesterday and my virus scanner started its auto-scan so I decided to take a break. When I came back and removed whatever viruses it found, my screen went black for a second then came back on. After that, my computer was unable to start any game, saying "Cannot load direct3d". I checked my graphics card and it was no longer detected at all by the system. Even the nVidia software and drivers had disappeared completely. In SIW and the Device manager it said I had no display adapter.

Honestly I'm not quite sure what exact graphics card was in there, but it's a high-end nVidia card about 8 months old. Is there anything I can do to make the computer detect it again, or is it more likely that the card is dead?

Thanks in advance,
Daulton

You need to reload the graphics drivers. No specs provided so I can't tell you which driver you need.

I tried to reload the drivers but when I installed them it said it couldn't detect any device or card. The nVidia website's auto detector couldn't find one either. The weirdest part is that the drivers just suddenly disappeared from my computer.

You need to post the brand and full model number of your laptop.

I assume you are still viewing Windows on the built in screen?

Is your laptop under warranty?

Hi, I'm having the same problem too. Laptop was running fine and well one night, shut down my com, turn on the next day and it can't detect my graphic card. The resolution got screwed up and I couldn't seem to set it back to 1980x1080. Highest I could go was 1280x720. So I restored to a previous point. Tried to open nvidia control panel and it says my card is not detected. Went to nvidia website it can't detect too. Went to look for its driver in the device manager it seems to be gone too, Now it's running on the integrated graphic card from Intel. Still able to view windows from the built in monitor.

Laptop is an Alienware M17X-R3 running on what I think is a GT540M.

Zavier, you need to start your own thread here in the hardware forum. While your problem may appear to be the same, your computer is different.
