PC turns off while playing games.

[reyiwnl]

I have a problem where whenever I try to play games like CS, Dota 2, etc. It just shut downs 2-5 minutes into the game. Not sure what's broken in my PC but I noticed that if my PC makes a fairly loud fan noise, it wont shut down and the problem doesn't show up. But if my PC makes small fan noise it just shut downs whenever I try to play. IIRC, last time I checked my temp it was around 80-85C.

My specs :
Intel Core I3 - 4160 3.60Ghz

8GB DDR3

NVIDIA Geforce GTX 560

I know it sounds horrible but it used to run games like CS, Dota 2, etc at 100-200 FPS.

My question is what is broken in my PC and what part should I replace in my PC, or is my GPU hella bad?

Hello,

 

That sounds like a PSU tripping a security to protect the components, also it could be temps since a GPU doesn't really like above 80-85°C or the CPU if it's above 100°C even for 1 second.

That GPU is a bit weak nowadays but it should be fine for the games you're playing if you get it to run properly.

It's hard to say what could be causing the shutdowns without seeing the PC and knowing the PSU model.

It might be covered in dust to the point that even the PSU is overheating, we have no way to tell how often you clean it.

 

Considering the age of the components, if the GPU is still using the old thermal paste from the factory it's definitely time to repaste it.

2-5min into the game means it probably isn't because of OCP, but I'm with you if you meant OTP in the PSU.

While a GPU might not "like" to run at those temperatures that GPU is reworked Fermi, so it will probably keep chugging along well into the 90°C without trying to save itself.

And CPUs will keep running full tilt even above 100°C because hey, the temp limit is 105°C so it must be fine, right? (I know this because I was testing an i3 with a poorly mounted heatsink and it reached 103°C with no signs of shutting itself off before I unplugged the system.)

 

So yeah, I'd clean the system as thoroughly as possible and look into replacing the GPU thermal paste (and you might as well do the same for the CPU).

That very much sounds like an overheating issue. You can check all of your temps using something like HWinfo. Check how hot everything is getting when you startup the game.
