Hi there, I am having the same problem as this person: Dxdiag doesn't recognize graphics card
I have updated my video drivers
several times and updated the BIOS as someone in the thread has suggested. The problem is still persisting for me
Also, the video card has randomly worked twice since this problem started.
-The first time I tried updating the video drivers it was working but stopped once i restarted the computer again. I tried re-installing the video drivers many times but it never worked after that until today.
-Just today i set up my computer after having moved and it was working. When i left the computer the screen could not be "woken up" so i had to hold the power button to shut down. Since then it hasn't been working at all.
Here are some screenshots:
