PC randomly freezes

[GalaxyGamer]

so my pc froze and then shut down instantly, like as if i held the power button down or flips the switch on my power supply then turned back on. anyone might know the cause? my guess is a system failure but not 100% sure. even if it was i want to find out why. this was happening occasionally but it seems to freeze a bit more often.

 

My PC Specs:

CPU: i7-2600k

RAM: 8 GB Kingston 

GPU: GTX 980

MOBO: ASUS P8H67-M EVO 

STORAGE: 240GB SSD

COOLER: CORSAIR H115i V2

CASE: Phanteks P400

MONITOR: ASUS (SOME MODEL #) 24" 1080p 60hz

PSU: 500w bronze 80+ evga

OS: Windows 7 Pro 64-bit

what temperatures are you getting?
does this happen frequently, or just this one time?
try stressing the hardware, does it fail consistently or at random?

usually in games im getting around 50c, its happened about 5 times in the last 2 weeks or so

also what should i use and for how long?

use the fur ball of death and a cpu stress tester

50c on cpu? gpu? both? what are your CPU and GPU temps under load? (please specify which is which)

first stress cpu and gpu individually, unigine benchmark and prime95 blend test should work nicely without pushing the hardware too hard.. if you can run both at the same time, try small ffts (maximum heat) in prime 95 and furmark for the gpu (watch temps closely, abort if it quickly rises to and exceeds 80-85 degrees c or over (this could indicate insufficient cooling)) if it's the PSU, it should fail pretty quickly as you draw more power with these tests than with normal or even heavy use

do you get brownouts in your location? (lights flickering etc) it could just be bad/dirty power that trips the failsafe of the PSU.. best solution then is getting a line interactive UPS that "cleans" the line input and also serves as extra protection should the power go out

Run malawarebytes, its free and it couldn't hurt.

what can i use for monitoring temps? for cpu? or will msi afterburner be fine?

msi afterburner should work, or realtemp or similar apps.. as long as you can get fairly detailed temperature readings under load from cpu and gpu, it shouldn't matter.

does it matter what unigine benchmsrk i do?

no, it's just something to run to stress the gpu.. 3dmark or catzilla will also work.

so i used prime 95 for 20 mins got top 60c and furmark was 80c-81c gpu and heres the unigine results

sorry for slow delay.. slowly dying from man flu

well, your psu is most likely ok as it handles itself under load..
one thing i thought about, seeing as it is fairly old hardware, visually inspect the entire motherboard for bulging or leaking caps.. 
also run memtest86 to make sure

hope you get better. no bulging or leaks. i also ran memtest86
