New motherboard & CPU-no POST

[ksteere]

I have a MSI KM4M-L motherboard with an AMD Athlon XP 2600+ CPU that will not boot. Power comes on and fan on CPU is running but I am getting no POST. I used my TechAid POST Diagnostic PCI card and received POST CODE of FF. I have made sure that the board is not shorting out on the chasis. The BIOS is a Phoenix BIOS D686. I would appreciate any replies. I am almost at the baseball bet stage.

The obvious:
Front side bus set correctly? most XP2.6+ CPU's are set to 166 (that's 333fsb) but some are 133 (266fsb)
Do a Google on your CPU numbers

You may have fitted the heatsink/fan unit 180degrees out? not obvious at first but the recess in the base of the heatsink should be positioned over the raised cam box on the CPU socket, fit with a small amount of paste if it isn't pre-applied.
If this proves to be the case (fitted 180degess out) then the CPU is likely damaged.
The power supply is faulty? even though it appears you have power, PSU's have several differant power rails, any of which can fail.
Addon card preventing boot (than can also apply to many other periferals) ie: external modems, printers, USB cards etc etc
The extra P4 connector isn't plugged in (if it has a place for one?)
Plugs and wiring generally firmly in place ( refit all connections)
Hard drive failure, often due to a PSU going bad, HDD's often go to ground (short)
Is it booting but without video signal?
Bad memory
