New computer build, everything has been working perfect for a few weeks. Recently while gaming it just suddenly died, and right away it tries to reboot itself automatically, the fans go on for a second then dies, and the computer is stuck in this reboot loop which fails to boot up.

I unplug the power cable, and wait for it to cool down.

When computer dies, its very hot. However, when computer is on and running all temperatures are good. Around 40-50 on GPU and 50-70 when gaming. 30-40 on CPU and rest.

After a while I can plug back the power again, computer works perfectly for 30min-5hours, then it can randomly die again even if i do nothing on it.


tl;dr
- Computer works perfect for weeks. Suddenly dies.
- Stuck in endless reboot loop (doesn't boot successfully, nothing on screen)
- Unplug and wait a while
- Plug back in, works perfect again for several hours until random shutdown without warning

But every part is brand new, except both hard drives. Which are 1 year old. Everything else in this build is brand new, and the computer was built just 2 weeks ago!
 


That doesn't stop them from malfunctioning. Every now and then, there comes up pieces that get damaged during shipping or bad pieces that go through the quality control.


Also: some of the problems do sound more like failing HDD, but some other problems do not fit that.

The HDD led is blinking a lot on the motherboard, but scanning the drive for errors on Windows says its working perfect. The HDD is the oldest piece here, but it is not old. Only one or more years. And its only full by 40% storage. Any way I can check further if it is the drive?
