So not so long ago I woke up in the morning to notice that my PC was power cycling. It was turning on getting to the mobo manufacturer logo then turning off and repeat. I quickly shut it down and check to see if there was something going on with the mobo, you know, smoke or burn marks. Everything looked okay so I plugged it back in and tried to start it again and this time the PC wouldn't even get to the logo, just power looping non stop. I shut it down again and tried to start it up, now nothing happens, at all. No lights on the mobo, nothing. So, what do you guys think? Power supply gone? It's a 650watt corsair power supply which I've had for like a year. My PC is mostly on, even overnight, I rarely shut it down. It doesn't go to sleep or anything, doesn't even dim monitors. Any feedback would be nice. Thanks guys.
