Ok here is the problem. My PC just turn off like a power cut like after 30 minutes. And if I turn it on immediately it turns off in 1 minute. But If I wait for like 10 minutes and then I turn on my PC it stays for 30 mins max and turn off. I checked the RAM, PSU, VGA and I don't have a way to check my MB. I thought it was a heat issue.
And then I had an idea to boot from a live ubuntu USB. Guess what, PC does not turn off while I'm in Ubuntu. My conclusion is there is a fault in my SSD or in my HDD or in windows 10.
If you guys have any idea about this let me know. It will help me a lot. And I'm gonna test my Drives. I will keep this port updated.

i3 4150
8 GB ram (4*2)
128 GB SSD, 1 TB HDD
Asus H81m-c motherboard
R9 380 4gb VGA

I wouldn't be quite so dismissive of the heat idea. Run a temp monitoring program like HWMonitor and tell us what your CPU cores (should be two temp) and video card are showing before it shuts down.

Yeah. I thought it was a heat issue. Then I monitored with HWM. Heats are normal. CPU is just 30-60 c. Not doing higher than that. I'm monitoring my VGA with afterburner. It's normal. I unplugged VGA and tested it. Same. When running on onboard graphics it just turns off.
And now my PC is running for 3 hrs on live Linux USB. The issue must be my PSU or drives, right? Coz when running on USB hard drives don't work. That means they don't need power. Or it must be a hard issue, right?

Depending on the distro, it is most likely using a good bit less of your system than Windows would. What about your motherboard and power supply (from the outside anyway). Is anything there getting especially hot?
