PC freezes with no warning signs and needs force reset

[Nemanja_3]

So just suddenly like a week ago PC just started randomly freezing and after it freezes I am unable to move mouse, type and video and whole screen are just frozen, sounds is still on for 20-30 sec. Even if you press ctrl + alt +del it still doesn't interrupt the sound. I installed newest amd drivers for GPU and updated windows. Any one have any clues on what to do ?

CHIEFTEC is not a good sign ,their power supplies are poor and unstable.

So you think the power supply just stops working ? Wouldn't then sound stop working in the exact same moment ?

Not saying that but hard to troubleshoot , when PSU isn't the greatest quality. Could b the card , but hard to tell.
