"my pc shuts off and the message "Power saving enable and the monitor will shut down in a few seconds" ...." Ok, so the PC does not shut off, it's just the monitor...!!!! Well, I'm sure you must have changed the settings through Control Panel by now. Reinstalling, Repairing, Rebooting in Safe Mode,.. No GOOD, coz' it's not a software failure. If your "Never turn off the Monitor" option doesn't work, then you've got to test the machine with a new monitor. Borrow someone's for a minute, or buy one --- New or Old, making sure that you can return it, if the monitor's not the issue. Else, you can keep that! Also, is your VGA cable firmly attached on the serial port of the PC?? In other words, is the wire that connects the "CPU" and the "Screen" firmly inserted on the back of the "CPU"? Hope you'd have your system up and running soon. ~@~
