Needing a miracle folks.
Just finished a new build yesterday around 4pm. Installed Windows 8.1, all drivers and updates and such. Got an hour of gaming in and shut it down before bed around Midnight. I got home from work today and, on suggestion of a friend, ran Prime95 to make sure everything was stable in case I needed to RMA anything with Newegg. I ran it for just over an hour and decided that was good enough for the moment. CPU temp lows around 15C. Peaked at a high of 85C. No errors. Checked Facebook and GAF and then I switched over to my couch to watch a movie on my PS4. I got twenty minutes into the movie and hear the optical drive spinning in the computer (it's an older drive I threw in for OS installation purposes). I turn around to see it rebooting. I watched it for a moment thinking "Golly, I wonder why it's rebooting." Suddenly everything went dark and it restarted again. I jumped up and flipped off the power supply as soon as I could. I opened it up, took a look around, felt various components to see if anything was alarmingly hot. Everything seemed ok, so I tried to start it up again. A few flashes of light and then nothing. I took the RAM and GPU out, disconnected all cables from the motherboard and started one piece at a time. I even checked the seating of the CPU and then cleaned it and reapplied TIM. Plugged fans and case connections back in. Tried to POST with no RAM and got the three long beeps and debug message on motherboard came on indicating everything was working up to the whole no RAM point. Turned it off, put the RAM back in, cleared CMOS, and tried starting with just the GPU and SSD still out. At that point it came on and I was able to get into BIOS. I was in the BIOS for maybe 3 or 4 minutes when it just shut off. Since then, I can't get so much as a single LED to blink. Any tricks or suggestions would be welcome at this point.
