PC Restart mid-gameplay

[DrunkKoala]

So, i've recently started to get this problem. Every time I open up a game (Any game) and play it for a few minutes (About 1-10) my computer turns off instantly. After about 3 seconds, it turns back on by itself. I can do anything else and it won't shut down, this occurs exclusively to games.

Additional Info
I have not changed anything in my pc for about 6 months.

Random crashes and restarts? It seems either the PSU/mobo or the GPU is failing. Can you confirm this by borrowing someone else's GPU and PSU and test them?

I'll probably go and get my pc checked out at a computer store and see what's messing up. I'll report back when I do.

First thing, replace that power supply, it's junk and most likely the cause of your issues.

Second, although not really an "issue", your video card is probably very embarrassed to be in a system with an i7 CPU and 16 GB of RAM. I'd replace that 730 for a proper card a few tiers higher to match the rest of the components. 750 Ti, Radeon R7 360 or 370, something that will actually enable the system to run games well.
