Hello:

I have a intel P4 3.0 GHz 1GB ram Intel MB Chipset d865gbf homebuilt computer. It has worked fine for 3 years. It just stopped working tonight. I have not installed any new items or software. It system when turned on just hangs. It does not appear to POST. There are no BIOS error beeps. I see no cpu info screen. I did a minimum boot (CPU, RAM, Video Card, Keyboard) with the same results. I did remove the ram to test the board and I heard 3 beeps. But once I replaced the RAM I heard no beeps and it still just hangs their. I also swaped Hard Drives with another one that I know works with the same results. I also attempted to reset the BIOS via the onboard jumper. If anyone has any advise of help please do so. Thanks.

You've done all the steps to find an issue with hardware, sounds like processor may have died, if it's a removable proc. see if you can try another one? If it's attatched to the motherboard, you would have to replace the motherboard

How about the Battery, try to replace that before anything

Long shot, but if you have multiple RAM chips, you could try booting with just one chip at a time to possibly isolate a bad memory chip.
