[SOLVED] PC randomly restarts

[lolbert]

Hi
So my desktop PC randomly shuts down. It seems to happen more frequently when Im gaming, but can also happen when im watching a video. The problem started today, and has happened about once each hour..
I had some problems yesterday getting the PC to even start, but I cleaned and dusted the inside, and it then worked perfectly for the rest of the day.
I'm using HWMonitor to observe temperatures and stuff, but it all seems normal. I also had a look at the event viewer, but I have no idea what any of that means. Please see the screenshots.

Do any of you have any idea of what it might be?

Thanks in advance!

It's the PSU , the +12v rail is falling out of spec.
Time to replace the PSU.

I would think it sounds like a temperature issue possibly? Do fans work ok?
Possibly clean out dust (make sure your pc is off first)

What parts do you have?
like @Dark Lord of Tech said, it sounds like a PSU problem.

It's the 12v+ rail falling out of spec and this causes the power to unlatch and then the system will shut down.

Ok thanks, I'll give that a try.
I currently have
Cooler Master G650M, 650W PSU
, but it seems that it is unavailable in my homecountry atm. What is important to look for if I'm finding a different PSU? That it has the same W output?

The quality of the parts, the effective, and the wattage all matter.
I'd remcomend a Corsair CX series or TX series power supply.
