My PC case's power button doesn't work

[steffeeh]

You see the parts in my sig

Just now I opened up my homebuilt PC to upgrade the case fans - everything goes smooth and nice during the work.
But when I'm done and click on the power button, then nothing happens...

The PC isn't damaged because I can turn it on through the mobo's power buttom, but the PC case's own power button doesn't work.
I've made sure all cables are properly inserted and tried pushing in the wires towards the backside of the power button in case they were loose, but nothing helped.
More than this, the USB ports on the same device as the power button, as well as the power button's LED lights - all work, it's just the Power On function itself that doesn't work.
The power button doesn't either work when I'm in Windows (if that helps). I've checked the BIOS, but I can't find any setting for the power button, and I've also tried doing Reset To Optimized Defaults, but that didn't help, so it can't be any wierd BIOS setting.
The whole computer is only a few months old...

Is my power button dead?

Hi

Are you sure power switch is connected to correct pins on motherboard ?

If it is then bridging pins with tip of screwdriver will turn pc on

If you have reset putton try connecting to power on pins

If case power switch faulty you have choice of swapping with reset switch, a new switch or new case

Fortunately your board has a power switch

Sounds like the your case's Front Panel wire is loose or inserted wrong.

If you look at reviews of the Be-Quiet Silent Base 800 case this is a known problem. I found this post talking about checking the contacts in the power switch connector:
"Had an issue with my power switch not working. One of the metal contacts in the plastic connector on the power switch wire was not seated completely. This resulted in much frustration as i though I was screwing up the motherboard pins. The connector is located under the top of the case."

Turns out one of the connectors for the Power Switch on the Standby-button had broke off, reattaching it made it work again and adding some tape to it should keep it in place, though if you have any more permanent solutions on how to prevent this even more, then let me know.

Thanks for your inputs!
