Er, do you mean the 2x2 4-pin P4 header?
Or the full 10x2 (or 12x2) 20-pin (24-pin) ATX 1.0 (2.0

You mean the PS won't start its fan? Or other? The only way
to tell is to in-line an AMP meter and check for current (or
at least probe parallel to any 3, 5 or 12V line and check for

Check the caps around the CPU.
Also, did you put in a new CPU?

I'd say the CPU is fried, and that's why your mainboard is
not starting up. The system can_not_ POST if the CPU is not
If you're getting beep codes, look up what they mean for the
mainboard's BIOS vendor.

??? What's wrong with MicroATX ???
I bought an older ViA Socket-462 MicroATX for $25 new
recently to go into an Aspire Q-XPack enclosure. Exact same
chipset as my wife's existing ATX version, which I told with
its tower case and 400W PS for $50 to a friend. Threw her
XP2600+ in and it worked flawlessly.
Most MicroATX mainboards are $45-60 these days, even the
latest GeForce 6100 + nForce 410 NV4x integrated video for
Socket-754. Socket-939 mainboards are $70+, although the
CPUs are a bit more costly (I'll admit).

Computer Geeks has a brand new, retail box Biostar MicroATX
with XP2600 for $95:
Otherwise, maybe you should consider a Socket-754 or 939
mainboard and CPU instead. Socket-462 virtually _died_ last
year, and the cost of a Socket-462 CPU can be more expensive
than a Socket-754 processor today.

Well, if you told me how much you paid for the mainboard,
I'll let you know. ;->
