Pc randomly turns off

[Danoniero]

Hi guys, today suddenly out of nowhere my pc decided to start hard shut downs. Now I'm selling this pc so I need to know which part is bad before I do.

 

I7 6700k

Be quiet 630w+bronze

No Discreet GPU

Asus z170 pro gaming mobo

2x8gb ddr4

Win 10

 

So whatever I do, be it browsing web or just sitting on desktop my pc will hard shut down randomly after 5 sometimes 10,30 minutes. Funnily enough plugging in ethernet cable seems to speed up the issue.

 

I obviously suspect PSU, all pc is like 5-6 years old now. I have a multimeter, can I check the PSU with it if so how and what to look for?.

 

Thanks

Temps?

Not sure what to check with the multimeter tbh but start with simpler things like, temps, reinstalling windows (since your getting rid of it anyway), testing individual RAM sticks.

Temps are fine 30 odd c idle and while playing some oldish games

Can't really reinstall windows if it shuts down every now and than can I.....

Does it only shut down while your in windows, or can you chill in BIOS?

Bios shut downs as well, worth mentioning that once it shut downs it won't come up for like a minute or until I replug PSU power cord

Best advice is to follow on online guide like this one. It will take some time and require you to accurately document, so its probably best to either take pictures or grab some pen and paper.

I finally got my new power supply in and it's all good now. PSU was faulty, PSU tester wouldn't show any faults as it only checks the voltages under no real load.
