[SOLVED] Weird problem

[egzon12]

R5 3600
MSI B450 MORTAR MAX
GIGABYTE 5700 XT
16 GB RAM
HYDRO G 650W PRO
M.2, SSD

So I have this weird problem that i cant figure it out.When my gpu idles at 780 mhz my pc always restarts or shuts down while gaming after a few minutes or hours,but when it idles at 6 mhz it never happenes. When it is at 780 mhz I have to shut down my pc for it to go back at 6 mhz, restart doesnt work. What can cause this? I did a clean driver install, tried stock settings, I even changed my psu. Can someone help me pls.Thank you.

The 6MHz and 780MHz you are seeing is most likely an 'effect,' not a 'cause'.
Have you checked your temps while gaming? Are any components downclocking?
