Everything is about a month old...

Build:
3700X
Asrock b450 M Steel Legend
Xcaliber 4000 MHz ram clocked at 3200
Evga 750W gold full modular power supply
MATX Case with ball bearing fans added
gigabyte Auroras triple fan 2070 Super
Evga 240mm liquid cpu cooler


Play 1-2 games of overwatch and pc will restart randomly during match... temps seem low and I did a Aida64 stress test for a while with no restart or problems... only thing i notice is gpu backplate gets hot, but gpu temps show low 60-70.

My girlfriend had the EXACT same problem with overwatch specifically.

In the end a Bios update for the motherboard resolved the issue.

i have the latest bios update and its only doing it in long games like csgo competitive and overwatch competitive.

Found out the problem was my power supply going out after all of this trouble :(... only had it for a month. My last power supply i bought from evga didn't work either and I had to rma it.

Im legit having the same issue, just built a new comp. been running fine for 2 months and boom 2 days ago it just randomly starts shutting off.. and I think im hearing some clicking sounds too. Ima try and replace my PSU and see if thats helps cuz I had a feeling that was the main culprit anyways! Glad everything worked out tho, im hoping I have the same luck lol
