Help! Is this a psu problem?

[aandinho]

So I started booting up my pc and got into the desktop, then the pc suddenly shuts down. Turned it up again, didn't do any task, then shuts down again. I tried:

-Reseating the cpu/cooler and changing thermal paste

-Boot up in the bios, waited for several minutes, but the pc doesn't turn off.

-Looked at 3.3v, 5v, 12v at the bios, and the voltages didn't fluctuate that much hovering +-0.02v.

-The psu fans still works

-The psu and the whole system is not overheating

 

 

Question: is this still a psu problem? Or is this an OS problem?

 

Edit: Specs:

i3 3220

4gb ddr3 1600

MSi h61m-p31/w8

Gt 420 2gb

Pheonix 600w psu

Windows 7 (the guy I bought it to, formatted this pc and then installed the OS this system has now, so it might be a cracked version)

Is there any possible problem? Except for the psu?

get a psu tester or measure the 12, -12, 5 and 3.3 volt wires against ground

[WereCat]

Unplug all PSU cables from PC components and start it by shorting green cable with any black cable on the 24-pin connector.

If it will run and not shut down it may be not a PSU problem.

How though? I want to do tests that doesn't require expensive items tho, i don't have money for that. Sad

if you don't have or can borrow a multimeter or psu tester (they are not expensive) then it might be hard getting a final conclusion.. a psu tester or/and a multimeter is most likely cheaper than a workshops diagnostic charge..

The previous owner used the whole for almost 2 years

Would this info from the bios suffice?

try getting a bootable disc like windows install cd or ubuntu, then remove your gpu, fans, harddrives and all but one stick of ram from the psu/motherboard so its only psu, motherboard cpu (heatsink with fans can be left in) and ram

does it start and stay on?

I would try that, but it may take some time as I have a busy schedule. Sad

this is assuming the sensor are showing correct results, but it seems to be within range.. though i doubt this psu has a 80 plus certification so it may not even handle the full 600w.. it might not be a faulty psu, but just a cheaply built low quality psu.. it's not listed on the PSU tier list, and i find little to no info outside the manufacturers website..
i would say get a tier 3 psu or better.. 
and for your build a good 450-500w should be more than enough

troubleshooting computers take time unfortunately, if you don't have time to do it yourself, you'll have to pay someone else to do it for you, it won't fix it self magically..
there are no shortcuts to troubleshooting
