Hi, My pc is still having problems. So its not a loose connection. What I'm wondering is can a video card overheat? If it can, that might explain whats happening. It ran fine all night, then suddenly shut out of windows and wouldn't boot back into it. However when I did boot up I could go into safe mode. So I don't know what's happening. Is there a diagnostic I can run? Also, I'm going to see if it works when I get home, 14 hrs to cool down should be enough time, lol. Thanks, Ang
