So our desktop home PC has had this seemingly endless string of problems for the last month. The problem this time is that it starts up fine, but after about 10 or so minutes (or it might depend on the amount of processes being ran, I'm too afraid of worsening the situation to do any further testing) the system shuts off. If I try to power it on again immediately it usually results in a shutdown before booting is completed regardless if I choose normal startup or safe mode.
All I've done so far is take a look at the Event Viewer, but I don't know much about what I've found.
Regarding its history of recent problems. The disk was reformatted twice before this (we had to transition from XP to 7) so I hardly think that this is a software issue? I'm suspecting either a faulty power supply or perhaps bad memory.
For the power supply I don't exactly have the tools to test it out, and a PC tech guy said that ours was running fine (doesn't hold much water but I didn't know enough to complain). In case of the latter, I've tried conducting a memtest but similarly it just shuts down before there's much of anything that could be done.
Will follow up on the specs as I'll be looking into the PC again soon.
