I needed to move some stuff around on my desk, it required taking the power block out, hence removing power from my main machine. Work done, I restarted the system, and it came up blue flagging "MACHINE_CHECK_EXCEPTION". Powering down and up a couple of times made no difference. It does not give any details as to what has caused this, no hex, just that string.

This has only just happened, so I*ve not searched yet, but in case anyone has a ready answer to get the thing running, (it has a lot of BOINC work running on it which I don't want to loose), it would help.
