power supply dead?

[dagz]

Recieved my x-navigator case with its 500w power supply that came with it. Also recieved my k8n neo2 platinum and 3500+ winchester core today. After i put it together I noticed i get no post screen. Now when I turn it back on it cant stay on for more than 10 seconds then it just goes dead. Also my button on my case does not work (crappy case anyone?). To put it on it is from the switch on the back of the psupply =/

For my post screen problem i guess i have an old bios version of kn8 neo2 platinum (my luck) and i have to send it in for an exchange. Anyone know how to do a blind flash to bypass this?

Normally a 10second shutdown on an Asus board indicates the CPU is overheating...check the CPU and heatsink.

The power switch could be the fact that if the PSU is on the blink, no power is getting to it.

I once got Asus to reflash my BIOS chip for me (was in UK and cost £3) when it didnt work with the new CPU

The PSU could simply be overrated junk, too. Very common to see that with the cheap freebie PSUs that the case manufacturers throw in. But yeah, if the mobo has a non-Winchester-compatible BIOS, that's not helping either.
