Come back from easter break to find one machine completely unresponsive. I've isolated the PSU, given it an hour or so with no power, checked the paper clip short, still no luck. I seem to remember someone saying to drain the PSU you short the two power pins out, still nothing.

I have a Corsair CX750M and a FSP 750 Gold, can I just plug these into the PCI-e power sockets and combine them or does it just not work that way?

Another machine was running at 50% hashing with lots of x hardware errors but a shutdown has that back up and running stable.
