pc keeps shutting off

[bingotj1]

so i built my friends PC for him over the summer and it was working fine the entire time until about a week ago when it started shutting off when he was playing games. I thought it was an overheating issue but after reapplying thermal paste and cleaning all the dust out and the cpu temp only being at 80 degrees F i determined that the issue was not heat. Anyone have any ideas on what could be wrong? tomorrow im going to breadboard his system and see if i can find out what is wrong.
He told me just now that it won't even turn on.

Specs: CPU: AMD Phenom II x955 Black edition
CPU Cooler: stock
MOBO: ASUS 970 PRO GAMING/AURA ATX DDR3 AM3 Motherboards
RAM: I'm not sure of the brand but he has 16 gigs
GPU: AMD R9 270x
PSU: EVGA Supernova 750 Watts

Breadboarding is a good start. Try another PSU if it fails the minimal boot. If still no boot, try a different graphics card.

1)always check windows event log viewer, see if it gives any clues.

2)80F may be the idle temp but cannot be your load temp (too low). You are sure its 80F NOT 80C (80F is about 27C)... and 27C is too low while gaming. 80C is way too hot for that chip. It should be 62C or less.

Download/Run HWMonitor and run prime95 (small FFT test for 2 min) or Intel Burn Test (2 passes std test). See what temps
you hit. Stop immediately if it hits 65Celsius (thats 149F).

3)If temp is ok, then it could be more likely the power supply dying or maybe the motherboard.


Thats an old chip, if mobo or the psu are equally old, either could just be at the end of its life.

Use HW monitor or bios to check the voltages. If the numbers are not where they should be OR are fluctuating.. could your culprit.

If the voltages are at the numbers the should be and also not fluctuating, it could still be the PSU.
Stick on a different PSU and see if it still happens.


-Post back if those three things dont help. They are the most likely things, but there are many many other posible causes

Could the power supply go out after only 3 months max? That seems pretty unlikely to me. And the mobo is also only about 3 months old. The temp while gaming was like 114 F and yes I am sure its not in Celsius
The PC won't boot on for long enough to open any programs to be opened.

My gut tells me it's probably the graphics card, but you really won't know until you troubleshoot. If you were overclocking, make sure to set everything back to defaults.

So I currently have it breadboarded and with all the excess components stripped (I just have the mobo cpu and psu hooked up) it's still shutting off. I'm thinking it's the processor because I paperclip tested the PSU and it worked, and the mobo lights will always stay on even if the PC isn't powered on so that just leaves the processor. Any second opinions?

The paper clip test doesn't necessarily rule out the PSU. I would try another PSU in the system and see what happens.

Well there isn't another PSU that we can use to test it out.

yup very unlikely, reset the bios to default? You can downlaod a free linux minut iso (doesnt matter which, use unetbootin to put it on a flash stick, boot from the usb stick, not you have an OS... if that stays on while you use it, maybe be a corrupted windows issue or a HDD

It's not the HDD because when I had it breadboarded it wasn't connected and the PC still wouldnt stay on.

Go to event cheker and see if there is any "kernel-power 41 (63)".
