New update:
Tested a Corsair RM 750x. Was able to boot up Windows and log in. Crashes intermittently when downloading or installed updates, with same BSODs listed above. Currently trying one stick of my RAM 8 GB. Crashed once, but trying to finish installing the Windows updates. Graphic card is updated, and will be updating the MOBO soon, hopefully. Surprised the 750x worked because according to online PSU calculators 550x should have been plenty.
Halfway through install new BSOD: IRQL GT Zero at System Service. Had to force restart, was about to log in and it crashed, no blue screen or error code, just stuck in a restart loop now. Back to using my HDD. Was also able to get the Samsung SSD working on another computer. Loaded and updated with no crashes. So this leaves RAM, MOBO and CPU? What should I be testing next?
Just crashed with HDD as well. Page in Nonpaged Area error.
