Hi everyone, I just built a new desktop for my uncle. After I put everything together and turn the pc on. It turned on for a couple of seconds and then shut off when it's copying the OS file (that's as far as it got). Then I tried turn it on again and it shut off even faster than the first time. So I though that was the PSU but its still the same after I change the PSU. Can anyone tell me what's the problem is ???
