Out of the blue the other night, my computer just turned off. Now it won't power back up. I swapped the power supply with a known working one and it does the same thing. I tried disconnecting all devices except cpu and ram and it won't power on. I even tried each stick of ram separately (there are two) to no avail. I made sure the power-on wire was seated firmly on the mobo, it was. I didn't smell any odors such as burning, etc. The CPU wasn't overly hot or anything prior to that. When I do hit the power switch, briefly just for an instant, I see the CPU activity light flicker, but nothing else happens. Please guys, I need some advice on what to do next. I'm thinking it may be a bad mobo, but I'm not completely sure. I hope it's nothing serious, such as a fried CPU. Thanks alot.
