I have recently upgraded my desktop with some new internals (ASUS HD7790 2GB, AMD FX 6300, 8GB of Ram, and an MSI 970a-G46 MOBO). Anywhere from a minute to 2 hours after booting up, my computer will just power off. No BSOD or anything, just powers off. Ive checked the running temps, but max CPU is about 57 and my GPU was about 50. I am starting to worry and need some help! Thanks!
