I have nothing over clocked, everything is less than 3 months old.
After I wiped my computer about 2 weeks ago, I have issues with the computer hard shutting down randomly, and when I try to reboot it, it won't do anything tell I switch the PSU power off and on. While in the shutdown state, the LED's on the mother board stay on (the decorative ones) so I know the PSU is still supplying power.
What I have done:
Yesterday, I re-installed all drivers including BIOS, performed stress tests on both the CPU and the video card continuous for 5 hours (100% load), and did not have it trip once. I thought I had fixed it. But I woke this morning to it being in the shutdown state, had to cycle PSU again.
Temps when idle are 28°C, at 100% load 55°C (CPU) and 62°C (vid).
I will say there was something odd, too, in my early stages of diagnosing. I thought it would be thermal Shut Down related, so I installed a monitor (CoreTemp), through the one night it recorded a max temp hit of 197°C, but didn't shut down. I found this very strange.
