PC restarting when playing games only.

[ColinBrah]

I've had this problem for a little while now but only recently it has become way too much to deal with. When I first load up a game it takes about 20 minutes then my computer restarts, no bluescreen, no errors. Then once my PC restarts, if I go back on the game it just instantly restarts again. This made me think it's definitely a heating issue. I've been monitoring my temps very closely, highest my GPU has got to is 75c and my CPU is the same, roughly 75c. I don't think it is to do with the GPU or CPU, I think it is the PSU. It's a 4-5 year old PSU (800w) but I've been checking the fan on it, it doesn't seem to spin anymore. Another thing which makes me think the PSU is faulty, when I shutdown my computer in the evening, all my monitors lose signal etc but the fans and LED lights on the computer stay on for about 1 minute then it shuts down fully. I'd just love to hear any suggestions people have. I'd rather not buy a new PSU and it turns out it's not that causing the problem. My hardware is:

Intel Core i5-4690K CPU @ 3.50GHz (4 CPUs), ~3.5GHz (Not overclocked)

Nvidia GeForce GTX 970 (Not overclocked)

MSI Z97 GAMING 3 Motherboard

Corsair Vengence 16GB DDR3 RAM

Corsair Hydro H60 CPU Cooler

Any help is greatly appreciated, thank you!

I did some checking with Intel and your under the Tj Max for that CPU. (100C) If your power supply fan doesn't spin anymore, that means its time for a new power supply. You are just asking for it to catch on fire, it will too. I had a customer one time complain of the exact same thing, his gaming rig would just shut down randomly. Well, when I had it hooked up in the lab, the power supply caught on fire!!! Here it turns out the fan wasn't spinning any more, he said he thought it only came on when it would get hot. :|

You reckon it's the PSU causing the PC to restart once it heats up past a certain point? I mean, it's 5 years old, definitely think it's time to replace it.

I would almost bet money on it. If your fan isn't turning, then there is something wrong and its time for a new one. 5 years is a good life span for power supply. I don't think I've had one that has lasted that long before.
