freeze PC freezing without any errors/bsod

[Naggash]

I have this problem, when PC just freezing up/hang on my old rig and new one. The only 2 parts left from old rig are PSU and GPU, everything else is brand new (since june 2020).

There is no BSOD, there is no critical errors in the event viewer, only 1 which is kernel-power 41 from me having to do hard reboot. Freezes are pretty random, PC can freeze 2 times within two hours and then 2 or even 3 weeks of flawless work. Since i build this PC, this happened 14times.

 

Most of the time when freezes are happening (IF not all), while me playing WoW. I don't really remember if this was happening without WoW running, not sure anymore. Screen just freezing, sound would continue for 5-10 seconds and stop aswell.

I have been playing other games for hundreds and hundreds of hours without any freezes going on, games like BL3, PoE, DOOM, Wolf, Outer Worlds and so on, much much more demanding games than WoW.

 

No, i don't have overheating issues.

Bios updated. Windows updated.

Ram checked for multiple hours in memtest86 and testmem5 @ anta777 extreme preset. No errors.

CPU is at stock atm, in prime it can reach 85c ~, running without any bsods/errors. In gaming it usually 40-60c (depends on a game) with some spikes to 65c (like when loading something up).

GPU is underlvolted to 0.95v at 1921mhz with 2 noctua fans instead of stock cooling. Fans set to 900-1000rpm, temp is up to 60c. No errors/driver crashes.

 

As i mentioned before, only GPU and PSU is from my old rig. I can't really test PSU, but i'm using it for about 6years now +-.

 

So yeah, i have tried many different troubleshooting stuff, but it's still happening. I'll try to get other PSU from a friend in a few days. I really hope its a somehow faulty PSU, which is messing up in low gaming load (like WoW).

 

Any help appreciated. Thanks

Sounds like PSU, just going to have to wait until you can get hold of your friends PSU to test

Well i really hope its an PSU problem tbh, even tho i don't really understand why its happening under low load (but never in idle).

Few days ago i even launched Realbench overnight just to check it out, since its load gpu/cpu/ram at once, everything was fine...
