Computer shuts off randomly but all the lights and fans stays working
So I built my own pc a week ago but I really need help,
the problem is when I’m playing intensive games, randomly:
monitor loses signal, keyboard shuts off, headset shuts off and the system shuts off but the mouse, all lights, and fans remain working at the same time.
The only thing I could do is press the power button to shut down and start the system again.
Here is the spec:
Ryzen 5 2600
MSI B450m-A Pro max
Zotac Gtx 1660 Super OC
Avexir Core 2 Memory 2x8Gb 3200mhz
Seasonic SIII 550w Bronze(2019 edition)
AMD Wraith Stealth Stock Cooler
I have two suspects
1. The CPU has 60C temp at idle. Msi afterburner indicates that the system has a temp limit of 83C so maybe the CPU shuts off when it reaches limit temp. But when I did a stress test the CPU temp almost reaches 85C and it didn’t shut off.
2. The PSU isn’t enough?
Note all parts are brand new.
What do you guys think, Did anybody experienced this?
Any help would be appreciated. Thank you.
