Hello geno368...
Have you tried a different keyboard? Usually, 3 long beeps indicate a problem with the keyboard or keyboard controller.

Check keyboard connection as this is what 3 long beeps usually is pointing toward.

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. I don't know the bios type since I get no video.

Disconnect everything from the Motherboard except
The goal here is just to test the mobo:
If the computer still will not boot up the please remove the motherboard from the computer along with the power supply
place the motherboard on a piece of card board larger than the motherboard,
this will eliminate a short from the mobo to the case which could be a possibility
Install the cpu with, 1 stick ram in dimm 1, power supply, case switch and case speaker
Connect ps2 mouse and keyboard along with the monitor
Repeat the above and power on
If the computer now boots into bios you most likely had a case short so make sure when installing the motherboard in the case that you use standoffs,
and they line up with the mounting holes in the motherboard and none of the standoffs touch anything else on the underside of the board.
Thanks to Cbarnard for these instructions
- keyboard
- mouse
- video output
- 20+4 powercable
- 4/8 pin 12v wire both coming from the powersupply,
- Cpu fan wire
- power and reset button to the case
- case speaker
