Help me tom's. My computer just recently started crashing whenever I open a game. Whenever i turn on any sort of graphically-intensive process, my computer's screen starts blacking out and coming back on again, in a loop (similar to when you switch between inputs on your TV) until it BSOD's. I am wondering whether this is a software malfunction, or a graphics card malfunction? the crash in itself looks very similar to a graphics card crash, however I checked the vista crash log, and this is what is says about the crash:

"The last sleep transition was unsuccessful. This error could be caused if the system stopped responding, failed, or lost power during the sleep transition."

So i presume my computer is going to sleep and waking up again, over and over rapidly enough that it trips over itself and BSOD's, which would be caused by a software malfunction. so wtf is going on???
