PC randomly restars

MarcT2 · March 9, 2021

Hello everyone, i build the PC myself.

My specs:

Ryzen 2700X

Gigabyte B450 Aorus Pro (No WIfi)

GSKILL DDR4 3200 MHz 32 GB (No XMP activated)

Samsung 970 Evo Plus 1 TB

Gigabyte Aorus 5700 XT

Be quiet ! 650W PSU (dont know the exact model)

Windows Version 20H2 (Build 19042.631)

After about 1 year, I am encountering the weird behavior, that the computer randomly restarts itself. I do not get bluescreens or anything like that, I think it just power cycles. It does not matter what I am doing, reading a PDF or gaming. I ran Prime 95 and Furmark parallely multiple times for about 40 minutes and it did not crash. While it ran Prime95 and Furmark I checked HWMonitor for thermals and power issues, the CPU did not run hotter than 85°C but GPU memory temp was 103°C. However, i did not get any weird behavior or graphic artifacts. On other times I play an arbitrary game or browse the web or read a PDF and it restarts itself.

What i already tried to solve the issues, in this order:

Ran tests to verify that Windows installation is working properly.

Reinstalled Windows.

Bought new SSD (the one mentioned above).

Reinstalled Windows.

Set minimum power usage of CPU to 5% in the energy options.

Installed new chipset drivers for CPU.

Installed new drivers for GPU.

Updated BIOs to newest version.

Unplugged PC from power and other external hardware. Held power button for 60 seconds. Reseatted RAM and GPU.

I tried finding errors listed in Windowds eventlogs. However, i cannot find the exact log, that tells me whats wrong. I checked a few log and goggled the error codes

but could not find a solution. I do not know a lot about trouble shooting and where or how these logs are stored and how i could share them with you.

I hope someone knows somehting about this issue or can help me somehow.
