So it all started when I switched my new build over to my new case. After switching over all my components the PC wouldn't post, assuming this was a Mobo issue I replaced it witch a new Gigabyte 970A-UD3P Having replaced the Mobo I chose to reinstall windows completely. this is were things started getting complicated. . .After starting the install I would often reach disk partitioning but the the install would freeze(sometimes it would make it to Extracting Files) After I tried a few time I made a new install disc but had the same problem for a couple more tried but then it worked.Celebrating the fresh install of Windows 7 Ultimate I started my updates. The updates went fine and didn't appear to have any issues. But after installing my updates my PC would start to freeze completely at random timings, only way to recover from the freeze was a hard shutdown. I assume I didn't see this problem during updates since the PC was usually only on for about 5-10 minutes.So, with this new problem ahead I started checking components, first I checked my voltages. Everything seemed to be functioning fine. I double checked CPU and GPU temps, my CPU was running an average of 32c and GPU 55c. So I went down to one stick of RAM and tested each one individually. I also tested the PSU separately and all voltages were normal. I also checked for bent CPU pins. Now knowing I had some really old RAM I figured it was a compatibility issue even tho the Mobo claimed it was compatible so I ordered some brand new Corsair Vengeance Pro (2x8GB) DDR3 1866MHz.After installing my brand new RAM I was prepared to downloading and playing games. but of course that wasn't the case. Now knowing that the only possible issue I could have left was maybe a dying PSU in its early stages. So I also bought a EVGA 110-B2-0850-V1 80 PLUS Bronze 850 W .If you read this far I'm sure you can guess that my PC still doesn't work. . .After installing the new PSU I powered on the PC and to my satisfaction the PC did not freeze, but instead is now randomly shutting off or restarting. Don;t know what else to do, please helpOther things I've tried:
Clearing CMOS after every new install
Wiping SSD and fresh Windows install
Using a different HD for OS
Updating Bios
Rolling back Bios
Disconnecting all other HDD's and USB headers
Disconnecting Power and Reset Buttons
Disconnecting GPU and see if the PC will stay on(it doesn't)
Staying in Bios
Another GPU
Updated all device drivers
Malware and Virus checks
Removing all Dust
Made sure no wires are shorting the Mobo
