Had a split second power outage in my house while the computer was on sleep mode, turned on my computer maybe an hour later and started browsing the web, and suddenly it turns off and I can't get it to turn on again. The LED light on my cooler will turn on, I believe my PSU fan turns on, my USB speakers will turn on, and the LED on my mouse and keyboard will turn on. However, nothing else turns on. Any thoughts on what the problem could be? I've had this computer for about 5 months. I have no idea if the outage is connected in some way since I've had outages before without problem. But I can't seem to diagnose the problem since a few of the above items are working while others are not. Thanks!

Update: I unplugged the power, went out for a few hours and came back to try turning it on again, and it worked. However, after about 4-5 hours of use (played Guild Wars 2 for about an hour, watched netflix for about an hour and did web browsing stuff), my screen "faded out" before the monitor showed "no connection" as if the computer turned off on its own. However, this time around, the power LED was on, the USB items were lit (keyboard, mouse), and the fans were still spinning. I turned the computer off manually, turned it back on, and it worked for about 3 minutes before the screen "faded out" again before turning off, with the LEDs and fans still working. Left it unplugged overnight, currently works fine now, but I wonder if it will shut off on its own again over time.

Hope this makes things a little more clear. If anyone has an idea what could be wrong it would be greatly appreciated!
