I didn't bother digging very far because it started to remind me of work so I got all panicky and cold-sweaty and stopped, but what is the flash procedure? I saw that there's a web method (which seems a bit dumb, at least in an emergency, since the IMM controls the network).
We had a little server room at the end of the corridor with a rack of switches and some servers. There was an ancient free-standing server that had been running for years but nobody knew what it was because it wasn't on any network plans and the sticky label had dropped off. Some Network people were mucking about with re-routing some new staff workstations and one of then decided to reboot it using the big button on the front. I did suggest that plugging in the spare monitor that was standing about a foot away just to check first might be clever, but that earned me a sneer. That wouldn't restart either. turned out to be something crucial to do with Stamp Duty. Cost more than £150 on ebay to rebuild.

The flash procedure seems to be "do it via the the web interface, if the IMM won't load, boot the backup IMM and do it via the web interface".
As far as I could see in the manual, if the backup IMM won't load either, replace the motherboard. Surely must be a header somewhere I could flash from, though?
Struggling to find any cheap replacement boxes on eBay, thankfully it's just a Plex and file storage server of little consequence to anything mission critical - glad I'm not trying to explain to the bean counters why the beans are no longer being counted.

No chance it's the CMOS battery?

Would surely still boot, just lose its BIOS settings? I've taken battery out and cleared CMOS to no effect.

Tried all that (don't have bother PSU to try).
Didn't OC the PSU so much as accidentally blow up half my house due to 1950s electrics going wrong

I've had a pc that wouldn't post until I pulled the hdd. Then it would post, boot from a cd, and ultimately from a new hdd.

Probably the PSU then.
Get your Multimeter out and measure the outputs of the 12v and 5v rails on the PSU motherboard connector and see what it is giving out.
