PC restarts suddenly and randomly.

[kisspatrik0602]

My PC restarts at very random times, with normal operating temperatures GPU and CPU both stays around 50°C-55°C. The PC restarts even I'm not running any program and restarts if I run a game, music player, web browser, Discord, last.fm scrobbler, etc... The restart happens without a shutting down screen, it's just a sudden black screen for 1-2 sec. then windows boot screen. This happened to me before but a Windows reinstall and/or unplugging a HDD and DVD writer solved the problem. The HD Sentinel show 100% condition on my C: drive.

Specs.:
PSU: Chieftec CTG-500-80P
CPU: AMD FX-6100 3.30GHz
Motherboard: ASRock M5A78L-M LE
GPU: EVGA GTX 750 Ti
RAM: 2x8GB Kingston HyperX 1600MHz
HDDs: C: drive Samsung HD256GJ, D: drive WDC WD10EZEX-00BN5A0

Did anyone have this problem before?

Edit: The BlueScreenView shows the dump file that writes: "Crash address: ntoskrnl.exe"

Have you tried a different PSU?
Very low quality PSUs, like that Chieftec CTG-500 could cause random shutdowns and other random issues.

No, not yet because the PSU is not that old.

They are as unreliable new as they are when used.
They use cheap components, which could damage your PC components.

Then probably I should change it. What kind of branded PSU's do you recommend then?

Your EVGA GTX 750 Ti minimum PSU requirement is a 400 watt or greater power supply with a at least 20 amps on the +12v rail.

The issue I have with that PSU or any cheap unit is that only the peak load is advertised.
So we have no idea how long it can sustain that load or any load for that matter.

If you take a look at Corsair CX450 a 450W PSU, it states 450 Watts Continuous power.
The same goes for SeaSonic G SSR-550RM and EVGA 550 B3 both 550W PSU, they state 550 Watts Continuous power.
So you know they can deliver their rated power at all times.
