The point made about the propriaty power supply could be relevant in
that it is not the connectors physical look that is different but the

I can't claim to have seen ALL Compaqs from that era, but in
general they did use standard ATX PSU except for a few
smaller form factor units that had what looked more like a
retrofitted AT pair of (single row) connectors.

I'd suspect power supply, motherboard battery, motherboard
capacitors. Clearing CMOS is the first try.
