I first encountered this problem when playing Magic The Gathering on Steam and the issue seemed to stay unique to STEAM however, I have re-installed windows and now face the issue of my desktop powering down at random intervals without even having steam installed.
I am running windows memory diagnostics right now and will also test the CPU, HDD & GFX and report back when I am done with them all.
I'm 90% sure my PC is NOT overheating, I have faced this problem before on a different desktop and my desktop feels no-where near as hot as the last one did when it was over-heating.
It is a custom built desktop with AMD quad core CPU and 16 GB RAM and a 1 TB HDD with on-board nvidea graphics and also on-board audio, can post exact specs later if required.
Is there anything else besides what I'm testing that might cause this issue?
Thank you for your kindness in advance.
