Its happened again, well sort of, but this time with a different graphics card.
I was stress testing my CPU with an old version of prime95 and when I stopped prime95 the video went black for a second then came back with a bubble saying the nvidia driver stopped working but has recovered.
Looking at the reliability data graph, at the same time as the screen went black it says a hardware error occurred. Looking in the Events viewer for system it says the nvidia driver failed and recovered.
I have tried the latest version of prime95 and cant reproduce this black screen. Could my P35 motherboard be on its way out as it was commissioned in 2008? Cant believe another video card is on the blink of different make, or could it be the driver, it is WHQL tested?
