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 **** button all along. I moved the rest to the power one and now everything is fine.
