There is a thread with the EXACT problem that I have but it was closed. I'm not sure what to do in this situation, only thing I could think of was start a new thread.
Blue Screen of Death caused by installing NVIDIA Driver
This problem started yesterday while playing a first person shooter. I think the card physically died, but I'm hopeful that I'm wrong.
Everything is the same as the other thread:
Using A8JS with NVidea Go 7700
Using Windows 7
Has been working fine for months on windows 7
Can run windows after formatting, before the NVidea Driver is downloaded - but of course i'm stuck with 800x600 res, and no 3D acceleration.
I've even tried installing Ubuntu, but it wont even get past the installation without freezing, and has some funny meshed colours around the mouse pointer.
