Computer turns off mid game.

grossjac · Apr 28, 2014

Computer turns off wont start back up until I switch the power switch off and on. This only happens when I am mid-game with the resolution on high.
It is a recently built computer with specs:
Intel I5 cpu
EVGA GTX660 video card
Corsair CX750w pcu
Asus Z87-pro MB

I was thinking power but it seems that 750w should be plenty. Possibly overheating? Any help would be appreciated!
Thanks, Jacob

your are not lucky because you have a fantastic motherboard and good psu...
did you upgrade the bios to the latest?

do you have an aftermarket cpu cooler?

Well, the first suggestion is to run a benchmark with something like Furmark or Prime95 and see what the temperature gets to for the GPU or CPU, respectively, when you run it.

It the case around the power source feels hot right after it shuts off but the CPU core temperatures don't get above 75 degrees C. Could it be air flow through the case? I only have one case fan in the front.

Also I do not have an aftermarket cpu cooler.

I can only assume it just overheats because it never gets as hot as it does unless I am playing games. In that case is it a component problem or just airflow/case problem?

your cpu is too hot

get a cpu cooler (aftermarket)
a cooler master evo is a good one

badboyrog2 :

Thank You, I will try this and hope it fixes it!

badboyrog2 :

So I got an aftermarket CPU fan and it helped with core temperatures but my problem is still happening. After a short while with high graphics it just shuts down again.

badboyrog2 · May 2, 2014

check the voltage at the psu if they are stable
let me know!

grossjac · May 2, 2014

badboyrog2 :

Check the voltage where? going into the psu? or coming out, and if so where should i check for it coming out?

The CX Series supplies aren't the greatest they have poor capacitors.

Could also be a defective card , because you have plenty of power.

grossjac · May 2, 2014

Yeah I checked the temperature of the card and it does not exceed 70C and it still shuts off.. Could it still be defective if the temperature is normal?

Dark Lord of Tech · May 2, 2014

Could also be a defective power supply , you have a great board.

Do you have another power supply you could try?

grossjac · May 2, 2014

I don't offhand but I could borrow one from someone if I need, that might be my next step.

Dark Lord of Tech · May 2, 2014

I would try that next.

As long as your heatsink is installed correctly , you shouln't be overheating.

try install hwmonitor here

Here is my specs in game. About 5 mins before the computer shut off.

Everything looks normal.

grossjac · May 3, 2014

Low resolution (it does not shut off even after hours). The only difference I can see is the graphics card temperature is 15C lower. Also the PCU is not as hot to the touch.

PSU shouldn't be getting very hot.

badboyrog2 · May 3, 2014

everythings look great...so it can be the ac power outlet.. can you plug your psu power connector in an others wall outlet? and give a try..
let me know

grossjac · May 3, 2014

badboyrog2 :

Did not even think of that, ill give it a try!

grossjac · May 3, 2014

So im pretty sure it is my PSU, the fan dose not seem to run at the right times (when it is hot/mid game). Can I fix this or is it just garbage?

Dark Lord of Tech · May 3, 2014

That CX750 isn't a very good supply , a new unit should fix your issues.
