PC random restart

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hello, I built a pc around 3 months ago. The issue arose about 3-4 weeks ago.

Twice a day my pc will randomly restart. No bsod, just black screen shut down and reboot shortly after.

Searching around online led me to believe it might be the motherboard or at least an issue related to it. I have a asrock b450m pro. 

In event viewer the only error tied to it is one related to amdryzenmasterdriver.

I have reinstalled gpu drivers, installed chipset drivers, monitored hardware. I can't seem to find the issue anywhere. It never happens under load or at high temperatures.

the rest of the specs are as follows:

-evga 600W 80+ bronze psu
-500gb western digital blue ssd
-rx 590 fatboy gpu
-ryzen 2600x cpu

If anyone has seen something like this before or has an idea on how to solve this issue it would be immensely appreciated.

	could be faulty Power Supply .. I had similar issues and that was the cause. Replaced the PSU and no more random reboots.

	I had same problem after upgrade CPU and RAM. After two months troubleshooting, found problem was BIOS dirty and buggy, because forgot to load default bios and boot into windows at least before flash new BIOS, gave me so much problem this time. and DDR setting not correct not spot-on. The funny thing is gaming high load is 99.99% OK, but idling doing nothing would random reboot a lot more, after many many different settings, finally found a couple of sets of settings very stable.
