    PC Wont Turn On. Components OK

    Hello all,

    I have stumbled upon the following problem and hopefully someone here can help me out.

    My desktop (ATX) PC, all of a sudden, stopped turning on. I moved the PSU cable and heard a small spark which caused my apartment electricity to shut down, causing me to flick the general electric adapter switch in the apartment. The PC does not turn on; the PSU does not turn on, no fan and no beeps from motherboard.

    My first guess was that the PSU was faulty and that there was even a possibility some components were fried. So I started testing.
    1. I took the PSU, a Rosewill 600W 80 PLUS Gold certified PSU, to a PC shop and they tested it with some sort of jumper and it seemed to be ok, everything was in order. Just to make sure, I still tried a different PSU, but still, the PC did not turn on, nothing again, no fan, no beeps. So in conclusion, I figure the PSU isn’t the problem.
    2. Motherboard: I thought my MSI H110M had fried, so I actually bought a replacement of the same model, but still nothing. I even tried the alternative PSU on the new motherboard. So in conclusion, I figure the motherboard is just fine (and I bought it for no reason).
    3. Other components: I figure if it was CPU, the motherboard would beep (?) and maybe even a fan would turn on? Same for RAM. I removed the graphics card on all these tests.

    Could the Front Panel be faulty? Any ideas? THANK YOU IN ADVANCE

    Hi @Yanez and welcome to PCHF

    Have you tried jumping the pins that turn on the board to rule out a faulty front panel cable?

      Thank you for the welcome

      I have not tried that. I honestly don’t know how. I have heard of using a pin to test PSU, is this somewhat like that?

        UPDATE

        I jump started the PC with a screwdriver on the Power cable and it turned on fine. I will now (once again) switch everything to the original motherboard. Now the question would be, how the hell do i fix that? replace the cable? or the front PC panel?

        Thank you

          Member has post the following on another forum so thread marked as solved,

          I tested the PSU, the motherboard, but it was the damn button all along. I moved the rest to the power one and now everything is fine.
