[ubuntu-uk] Hardware failure?

Before going down the new PSU route, do you have any power conditioners on
the mains supply to your box?
If not, that would certainly be the next purchase I'd recommend, followed by
the PSU afterwards.
To my inexperienced eyes, if a full power off and break with mains is
required to reset things, it certainly does point towards the PSU, but it
could still be spikes coming in over the mains and causing the PSU to
wobble. In which case, even with a new PSU you'd still be liable to
wobbles, but maybe not as dramatic as you get currently.

I really do feel for you. It's one of those annoying problems
especially when you don't have compatible hardware kicking around. I've
had two Socket 754 motherboards die on me through power surges whereas
the CPU survived. Usually it's been a case of buying a new motherboard
and hoping that it works as no one I knew had a compatible board and
CPU. Sods law one of the companies I do contract IT support for now has
a stack of machines with Socket 754 boards and now I'm on a Socket 775
Pentium Dual Core and Socket AM2 Phenom (again, no compatible boards
although touch wood things are working okay).
Just a thought, have you tried getting in touch with the person/company
you got the machine from?
If you ask me, if you bought it new you should have a warranty on the
machine even if it was built by a small system builder.
