The pc had been giving some intermitent problems when playing games, it would sometimes black screen, but still be running. No option but to press the off button, and leave it a while, otherwise no reboot. I recently cleaned it out of all dust because i feared it was an overheating issue.
It worked fine for a couple of days, actually no black screens. Then one night it switched off, no warning... just off. No reboot till the following day. All was fine it seemed, as it worked again, then off it went a while later. I managed to get it re-started, only for it to switch off one last time, and thats it now... it will not reboot.
Im no expert on the hardware side, but i took off all connections on the back, still no reboot, i took out the ram and no reboot, only thing i didnt try was the graphics card... however, when i press the on button all it does it spin the fans as if its going to boot, then lights appear by the bottom right side of the ram, 1 yellow and 1 green. Looking in the manual it means its slight over and medium over voltage of what ever the lights are pointing to.
I cant make up my mind if its power or motherboard now... anyone have ideas plz? (The pc is about 4 years old now)
