Pentium 4 error beeps on startup

[romulan]

i have an old pentium 4 SKT 478 system, the cooler broke on it and now when i switch it on it beeps 5 times, then a pause and 5 beeps, this continues with no signal to monitor.
looking at error beeps on the net, 5 beeps points to the processor, but i have changed the processor for another and it does the same.

Anyone any ideas?

thanks in advance

i tried another processor with the same result, will try re-seating the memory later.
i would just dump it but my wifes got loads of files on it she needs to keep.

anything else i can try??
