The other thing that started happening was waking the computer up to find a blue screen with diagonal lines and horizontal lines that looked like stitching. When this screen appears, I have to hard crash the computer. I figured this might be a video card thing, so I just replaced it yesterday. However, I don't see how the SACHS thing could happen with a video card issue.
It happens totally at random. It could happen twice in one day and then not again for 3, 4, 7 days. It is also totally random whether I will find the blue screen or the SACHS wall.
Any thoughts? The original video card was a 7000 series NVIDIA card and the new one is a 9000 series. I am running XP professional, digital video cable. I know the computer is clean of viruses and malware because I just sent logs from my computer to that forum to make sure I was clean. "Extreme Boy" suggested I try this forum since he had never heard of it.
