  1. I've recently built a new computer for myself and has been running perfect for a few months. A couple days ago whilst gaming/browsing my monitor went into power safe mode and shortly after my computer shut off, I tried to start up again only to have the same problem occur , the only old parts were a graphics card and psu, I just got in a new gpu and installed it successfully. Same problem occurs. All fans are running properly including the heatsink , processor core temps are around 39 , everything seems to be running ok? Thoughts?

    Check event viewer to see why it shut down.

    You'd probably want to check the power supply voltages in the BIOS; if you see a large deviation (greater than +/- 10% of the nominal value) on any of the three major voltage rails, you've got a dying PSU.
