PC force shuts down when gaming

[nexezz]

Rig:
ASUS Z87 Pro
Intel i5 4770K
Cooler Master Hyper 212X
ASUS DCU-II GTX 770 2GB VRAM
Seasonic S12G 650W
16 GB RAM

Hey!

So I had my rig for about 2 and a half years now and never had this problem until now. My PC force shut down on me 3 times in a row in less than 5 mins of gameplay in CS:GO. I have all settings set to low if that helps at all.

So I'm not sure what's the problem here. I initially thought the problem was in the CPU that I overclocked. So I underclocked the CPU to 1.0 V from 1.25 V and same problem it shuts down in less than 5 mins of gameplay.

Sifting through similar threads, they seem to have the same problem of having a crappy PSU in their rig, however my PSU is the Seasonic S12G 650W, which is rated at Tier 2 according to the PSU tier list 2.0 and should be more than enough to power my system as it has done so reliably in the past 2 and a half years without hiccups.

Just to add on, it ONLY crashes when gaming and nothing else, I am browsing google and watching YouTube videos absolutely fine right now.

Any help would be much appreciated! Thanks in advance!

Overheating maybe?

Im guessing you meant you undervolted to 1.0? That will not help. Keep it at stock voltages and clocks while you figure this out. It may be your motherboard defending you from some power fault. I would try swaping out the PSU if you have a friend with another build or something. If your CPU was fried from overclocking it wouldn't boot at all. That has been my experience anyways. Does this happen in all games?

Still sounds like a psu problem. Try to swap out the GPU first if you can. If you can, do some test with the internal graphics. But you need to swap out the PSU and do a test.
