Hello there.
I have a little problem.

Yesterday my PC suddenly crashed with the error "ASUS Anti-Surge detected an unstable power supply unit on the last power-up". So I was thinking like, yeah ASUS is little bit weird in this and turned it off today. I was gaming a little bit everything was ok. And then suddenly a weird static buzzing and noise in my headphones started. Monitor goes white and after a while a went to windows and it has ended. But the audio was disconnected (it was now in my monitor speakers only). Then I did the same. Started a game and again the same happened. But the monitor was purple now and I needed to restart the PC. When I watch videos, twitch etc. everything is ok it happens only while gaming.
My GPU is GTX 1050 Ti
And PSU is CoolerMaster 600W
They are probably 3 years old.

Do you think it is bad GPU or PSU?
Thanks for advices.
 
That's actually not a very good high quality PSU though, IMO. Can you check the GPU by using some other PSU model, if possible ? Which Motherboard do you have. and how many RAM sticks are installed ?

Does your board support onboard graphics/iGPU ? Try to run a MEMTEST on the memory modules to check for any errors, if need be. What is the GPU and CPU temp value while gaming ?

Memtest is ok. I was dealing in the past with overheating (i tried everything. tested gpu, cpu ..). I have to buy only another PSU. Motherboard is ASUS B150M PRO GAMING. 8GB of ram Kingston Fury HyperX.

Today I have bought another PSU. And after 10 mins of gaming - freeze... Im so angry. Yeah and before the new PSU it even crashed in Windows (Opera).

Its really strange. Because it was freezing after 5 minutes of gaming and then I set little bit higher voltage to CPU and it freezed after 30-45 minutes? Maybe just coincidence?
