Does your monitor have a separate PSU? I ask as this computer started
behaving erratically, to the extent that I set up a spare on to use.
Just before switching over there was a 'pop' from the monitor PSU and it
died. Using an alternative monitor stopped all the computer problems!
It's a bit bizarre, but it's possible it might not be the computer at
all at fault.
