I was playing an MMO (video intense) when my screen just went blank. The only thing I could do was hit 'reset'. My computer loaded normally after that, and I managed to load it into safe mode with no problems. I looked at DeviceManager, everything looked cool, but when I then tried restarting it and loading windows normally it seemed ro go ok untilthat animated part, when those 4 colors join together on the screen to form the Windows logo. My screen went blank right after that, Aand that is what it keeps doing now. I tried entwring my password and hitting enter at that stage, but there seemed to beno response.
My OS is Win 7 Ultimate.
How do I troubleshoot it?
