I've been getting seemingly random shutdowns on my PC the past two weeks, doesn't seem to matter what I'm doing, gaming or browsing the internet (however it does seem to be fine when idle). To add to this since I built the thing about 6 months ago it's been having issues booting up the OS properly as well, though it'd go through long stretches without any issue then appear again. The USB ports seem to cause interference with the OS booting properly or something. I've noticed if I have things plugged in and it doesn't boot, taking the cords out tend to resolve it.
Through the event viewer after a random reboot I've been getting errors "Tun Mirror" and "License Activation (slui.exe) failed with the following error code:
hr=0xC004C003"
Event viewer also gives me a Kernel Power Event 41 Task 63 random shutdown critical error after every random reboot.
I should stop here and mention that I received a KMS activator copy of Windows 8.1 Pro from a friend through an install disk and thumbdrive. I'm wondering if this could be the culprit to both my issues or if it's the PSU, or both..
So far I've made sure all drives are updated, including bios. I've ran memtest to rule out ram, I've checked my connections, and switched the power cable, checked system temps and voltages, and cleaned out dust in the case. When the PC reboots there's no BSOD, just powers off and right back on as if I hit the restart button.
I'm probably just going to buy Windows 8.1 so I don't have to deal with any more activation key BS anymore regardless, but is there anything I'm overlooking or I should check as well?
Any possible help is appreciated! I'm still learning.
