Rx 480 Red Devil crashes to no signal

[Scabral54]

I and trying to troubleshoot an issue for my buddy. He bought a cyberpower pc off amazon and lately its been "crashing" randomly. It will say lose its signal to the monitor but the system will remain on and running. Only way to fix this issue i have seen is to hard reset. I have tried another power supply, checked for a bios update, uninstalled and reinstalled the drivers. Still getting the "crashing". It will happen in game or idle on the desktop. Seems to be completely random. The system seems to ramp down after the "crash" but cpu and gpu fans are still spinning. Wondering if anyone else had this issue or has heard of it. 

System specs:

Ryzen 7 1700x

16gb (2x8gb) ddr4

Asrock AB350m Pro4 

450 evga bronze power supply ( tried thermaltake 600w gold psu)
