PC restarts. PSU problem? virus? *Solved*

[Tuzara01]

It started recently random restarts while gaming. Some times as soon as game starts some times at game end and sometimes no restart in full night of gaming. No temperature problems everything is under 65C under full load.

I was hacked 2 days ago (hacker changed my passwords and tried to steal a bunch of money from me) using kasperski zemana and hitmanpro i think i removed him? But the restarts continue. I am using latest drivers.  I built PC myself. 

When running CPU stress test no problems when running GPU stress test i get a reset very quick. 

Again its random it can take 5 seconds it could take 2 minutes. At time of reset temperature is never more than 55C. 

There is no artifacts, altho there are occasional frame drops while gaming. Dips from 120fps to 60-50fps (which never happened before) drop does not represent higher intensity its random.

Linus Forum any suggestions and tips are welcome! Thank you  

Problem seems to be solved with changing the PSU supposedly the cx750 has a working temperature of up to 30C. Swapped for Evga SuperNova 750W P2 works perfect up to50C.

Try a virus/malware scan on your PC, and look through the start up programs on task manager for anything suspicious.

The virus was Temp\phantomows\bin Csrss.exe and every time kaspersky tried to delete it it reset my pc or crashed so had to use zemana and hitmanpro to remove it. But all 3 programs show nothing left. I used to have network spikes every 3 seconds while idle so i suppose hacker was LIve at the time.

Use Malwarebytes and Adwcleaner to get rid of what you can.
