My computer shuts down exactly after 30 mins

[The Lucky One]

My computer shuts down exactly after 30 mins (I checked it in windows logs -> system) even if i don't do anything. Nothing overheats nor it is PSU problem supposedly. Maybe something wrong in BIOS and how do i fix this? Can't really play because of this...
System components:
- Asus GTX 960 strix (GPU)
- Intel i5-4570 (CPU)
- Asus B85M-G (motherboard)
- Aerocool X-warrior Devill Red Corsair 550W (PSU)

Aerocool X-warrior Devill Red Corsair 550W ???

I'm assuming that he has an Aerocool X-Warrior Devil Red case with a Corsair 550W.

First things to try are checking your BIOS for some kind of timer (if it's truly this exact), making sure you're on the latest BIOS and failing that, a CMOS battery reset.

I hadn't either, Aerocool's PSUs make me not want to be familiar with anything else they sell. Just Googled it, lol!

i did CMOS reset and had this running locked for 2 h straight (I've done CMOS reset before and it still kept shutting down after couple of weeks)

Out of curiosity, are you still within the 3 years for warranty? If you are and you're anywhere close to the expiration, I think I'd just RMA, as this could be a fairly atypical issue that's trickier to resolve, something like a VRM or some electrical issue monitored by the motherboard after a certain timeframe.

Well i was thinking of going to the store i ordered the parts in and try ask if they could fix this. Worked fine yesterday after i left this running for 2 hours in locked mode but this morning this keeps shutting down again.

By any chance have you recently upgraded your CPU?
I've been having the same issue after upgrading from a Pentium to an i7.
After I switched back to the original CPU the problem stopped.
I've been doing a lot of research and it seems that the issue is actually with the Intel Management Engine.
If you've never heard of it, don't be surprised, neither had I.
It's a subsystem on the newer (2008+) processors that performs tasks during boot-up, while the computer is running, and while it is asleep.
In 2016, the me_cleaner project found that the ME's integrity verification is broken. The ME is supposed to detect that it has been tampered with, and, if this is the case, shut down the PC forcefully after 30 minutes. This prevents a compromised system from running undetected, yet allows the owner the opportunity to fix the issue by flashing a valid version of the ME firmware during the grace period.
The Electronic Frontier Foundation (EFF) and security expert Damien Zammit accuse the ME of being a backdoor and a privacy concern.
Personally, I have yet to find a way to correct this issue, but I haven't tried flasing a valid version of the ME firmware, but I am still looking. I hope this helps point you in the right direction.
