I am trying to boot an older PC running XP and when I power it up, I immediately get 3 long beeps and then the cd drive powers up. I don't get the post beep, video or even keyboard power. I have tested the PS and it shows well within range. I have made an xp msdos boot disk and it doesn't work at all. I put in my xp cd and it spins but doesn't work either...Where should I go next for testing? Thanks

Three Long Beeps indicates a Keyboard error. Try another keyboard.

Are you using a USB or PS2 keyboard? Is the PS2 socket good?

Thanks for the replies. Here is what I have: It is a custom build by a local company and is about 3 y/o. I updated the ram to 1GB last year. It is a P4 processor on an Intel MB. It is an 80gb sata drive and it has an Allied 300w ps that I tested with a meter and is well within range on the 5 & 12v. It has a 128mb GeForce video card.
These are the steps I have made: Removed the ps2 K/Board and replaced with a USB. Re-seated the memory as well as the video card. Unhooked both the floppy and cd drives.
As soon as I power up the pc, the fans come on and I get 3 long beeps immediately...then nothing...the monitor power button just blinks like there is no signal. If I boot with the XP disk, it does spin up, but nothing elso happens. I looked closely at the MB and see no expanded capacitors and all connections seem good

The Beep Codes don't indicate a power error but the Allied PSU is a very low quality unit. Do you have or can you borrow another PSU to try?

your specs do not give enough information detail,for you to receive a accurate reply

what are you running
video card/pcie/agp
cpu
m/board/brand/model
ram
power supply
brand
wattage

check the listings in the bios for voltages and temperatures and post them
