Help! System will not turn on...

[azcn2503]

I've just installed a new Zalman CNPS9500. I have reconnected the fundamental cables (power to motherboard, and power button cable), and when I press the power button, I hear a faint electrical click sound, and the red light on the motherboard flashes - but then it does nothing.

Any ideas? This is £2000 worth of computer here!!

Try a different psu? sounds like its that, be sure all cables are on tightly, did you overtighten the zalman? if it was working prior to installing zalman you may have damaged during installation or not put everything back properley, track back and make sure everything is ok

Have you connected the CPU power header (4 pin square thing)?
Wont do anything without this.
