Weird problem in new PC

[ggee]

I just built up my new PC, but whenever I plug in the power and then switch on the PSU, the PC starts itself without ever going to windows, bios or anything, no picture on monitors either. Everything is on: fans, HDDs, GPU fans, CPU fans etc. The same thing happens when I turn the PC off with powers still plugged.

The only way I can get my PC to boot normally is to switch the PSU power on, then after the mobos power button lights up to show sign that the power is on, I have to hit the power button. If I don't hit the power button in time, the PC turns itself on without actually doing anything (what I described above). The PC works well when I can get it to boot but not being able to keep my PC off while keeping PSU on/getting it to boot is pretty annoying.


My setup:

Intel 2600K
ASUS p8z68-V Pro Gen3
MSI GTX 580
Corsair TX 750W V2
8GB DDR3 Corsair Vengeance 1600Mhz CL9
Intel 510 120GB
1TB Caviar Black
1.5TB Caviar Green
1.5TB Seagate 7200rpm
BitFenix Shinobi
Antec Kuhler 620

Try booting with the bare minimum, 1 hd, onboard gpu, no addon hardware or usb devices, 1 stick of ram. It sounds like your case have a short in the wiring.

Check and re-check all your cables/connectors.

try unplugging everything on the 20-8 pin "system panel connector. (manual page 2-23)
then plug power back in to power supply.
nothing should be running at this point. if so, now push the red power button on the motherboard...it's next to the reset button on the motherboard. if it now powers up you had something plugged in incorrectly (system panel) or your case power button and or reset button may be at fault.

I've tried it without the 20-8 pin system panel connectors already. The problem is that the mobo turns everything on by itself without ever actually booting.

Will try unplugging everything later when I get more time. Sounds weird that it could have a short tho since when I get it to boot, it works normally
