I built a PC for my son for christmas for him to game on. We got it all together on new years eve, and after about 2 hours of working it shutdown and rebooted randomly with no error messages. This had been going on for about a month. Then finally about 2 weeks ago the PSU died. I replaced the PSU, and here is where it starts to stink.......

With the new PSU it booted into windows 8.1 64bit right away. logged in and after a couple of minutes the pc shutdown. to get the pc to come back up we had to unplug it and wait for about 30 seconds for the green light to go off, then plug it back in and it would power again and repeat the same issue as above. I shut down the auto surge protection and the issue still persisted

Finally I think the 8.1 install became completely corrupt. I tried to repair the OS with the install disk but it did not work. We finally formatted the harddrive and installed XP. IT seemed to work brilliantly with no shutdowns. So the hardware looks good.

I formatted the hard drive again and tried the install of 8.1 again. it copied the files to the hard drive, rebooted and during the install and setup it crashed and had to unplug it again.

my friend read somewhere the clocking needs to be hardcoded on this mother board for windows 8.1 64 bit. Is this true?? Can someone please help, my son is dying to game with his friends online...

Here is the parts list
CPU: AMD FX-8320 3.5GHz 8-Core Processor ($149.99 @ Amazon)
Motherboard: MSI 760GM-P34(FX) Micro ATX AM3+ Motherboard ($53.66 @ Newegg)
Memory: A-Data XPG V2 8GB (2 x 4GB) DDR3-1600 Memory ($82.98 @ Newegg)
Storage: Western Digital Caviar Blue 1TB 3.5" 7200RPM Internal Hard Drive ($59.66 @ OutletPC)
Video Card: Asus GeForce GTX 650 2GB Video Card ($134.99 @ Amazon)
Case: Cooler Master Elite 431 Plus (Black) ATX Mid Tower Case ($44.99 @ Newegg)
Power Supply: Logisys 550W ATX Power Supply ($19.99 @ Amazon)
Optical Drive: Lite-On ihes112-04 Blu-Ray Reader, DVD/CD Writer ($62.98 @ SuperBiiz)

Solution
Logisys PSUs are useless. Replace it with something decent, particularly with that CPU.

To future proof for a faster GPU, I'd look at a 550W+ PSU from the second link in my sig.

Took out the video card... same thing happened.. loaded the windows files, then it rebooted after loading files and started booting then crashed.. now at point where i have to unplug to get it boot again. could it be bad mother board.. are there recommended clocking settings for win 8.1. again XP booted fine..
