A few times now my pc has suddenly gone to sleep while ive been downloading or playing something, it's shut down while using unreal engine, while downloading a large file from chrome and some other times but the odd thing I'd that it's more like a coma as I cannot wake it up and I can't turn it of with the case power button so I have to turn off the PSU, any ideas what it could be?
For info I'm using:
Motherboard:Rog strix b450-f
CPU: Ryzen 5 2600
RAM: 16gb 2666mhz (I know it's low)
GPU: Rog strix oc Rx 5700 xt
CPU cooler: h100i
Storage: only a 2tb wd blue HDD nothing else
