Computer turning on, no bios, no display, no beeps..

[woms14]

Hi,

I have a pentium 4 1.9ghz pc.

First, the chip was replaced, it has now been replaced 3 times, none which power on the machine (all the same configuration, 2 known to be working).

When the ram is removed, the motherboard beeps 3 times (Intel D845WN)
Ram placed back in, one at a time (3 slots, 3 sticks) nothing.

Tried 4 different video cards, 2 PCI 2 AGP.

Tried a new power supply.

Removed the cmos battery and replaced it about 5-10 minutes later.

Reset the bios through the motherboard jumpers.

Have tried to remove and reconnect all cables (IDE)

The harddrives/cdrom are all getting power, all fans are turning.

Is there anything else that I've missed? Any idea what the problem can be? Thanks.

I think you should stick a fork in it, it's done. It sounds like it's dead to me. Have you checked for popped caps?

Just the fact that the chip has been replaced 3 times means something is wrong, maybe the chip keeps overheating.
