Question : Problem: PC won't start - Fan's don't spin

Hi

I recently bought an old Compaq 5100 workstation from ebay. The specs are:
2 * PII 300
256 MB RAM

There is a fan mounted in the front of the case for the CPU's and 1 in the rear for the PSU.

When I push the power button the PC tries starting but it keeps restarting every 1 or 2 seconds.

I removed the front of the case and tried starting it ... it does exactly the same.

So I checked the power button connections and made sure they were firmly in and now it does nothing ... the fan's won't even spin (the LED on the motherboard is on)

Has anyone got any ideas what could be at fault here?

Thanks

The cas may have an intrusion detection switch.  You might be able to turn it off in the BIOS (once you get it working again).
