Similar crisis here with my desktop. Turned out that the hard disks (yes, two of 'em) were substantially undamaged, 'twas the power supply. Long story short, bought a new s/h computer and plugged them in via a USB caddy, and as far as I've discovered so far, no data lost.
Reinstalling the Sware on my new machine (where licences allow) is going to be a PITA, but phew!
