Assuming the monitor will power up: Take power cord from monitor, unplug from the monitor, plug it into the PC, then plug that straight into the wall. This will rule out (or in) the power cord and the port on the surge protector. (I know, I know, it can't possibly be the power cord... But it could. Easy fix if it is). ASSuming it still doesn't work - 99% it's the power supply.
