This has happened 3 times now, and seems to be becoming more frequent (aka twice in the same day). The system freezes, then monitors loose signal, the system is however still on as the motherboard lights are still on.
I also noticed that the GPU fans are trying to spin, but start then immediately stop, i also noticed, however, im not sure what this may imply, is that the RGB ring on the R7 1700 cooler fades in and out red.

System:
Ryzen 7 1700 (no OC)
Gigabyte Aorus x370 gaming K5
Powercolor PCS+ R9 380 4GB
16 GB Corsair vengeance LPX
XFX TS 750W

im rather concerned that the GPU may be about to die, so any help would be greatly appreciated.
The most recent time this occurred the system was not under much load, just visual studio open, not compiling.
