HI all,
Just put togther a new pc built on a P5K mb, 6600 quad core cpu. Got
everything in place, press the power button and the CPU fan starts,
but quickly shuts off -- nothing else happens. No HD whirl, nothing.
There is a green light on the motherboard when I plug it in though.
This also may help...I swapped out the 450w power supply in the case
(Antec Sonata II) for a new Silverstone 600w. When I disconnected the
old one, I noticed that a connector that ran from the power supply to
the mb..it's labeled "pwr_fan" does not have the same connector built
into the new power supply. This may be the problem but I'm not sure
what to do about it if the new power supply just doesn't have that
connector.
Thanks for any help.

All you need is the heatsink fan plugged into the correct header. The
pwr_fan is for those PSUs that have a connector so you can monitor the
PSU fan (don't know why anyone would want to, though). The BIOS doesn't
care if it's there, or not. Just the CPU fan connector.

Do you have the 4x4 pin connector plugged into the 4 pin socket near the
CPU?

When it comes on momentarily and goes out, have you waited about 10-15
seconds for it to come back and boot? My P5B does this and it seems
common on Asus MBs. It comes on momentarily to check settings, then
shuts off. If all is OK, it will come back on in about 10-15 seconds
and boot from there.

Oop...I forgot the 4 pin connector:(
Thanks!
