Make sure your power supply is set for the correct region you are in, if that does not work, check the obvious stuff like your monitor having power and being on and all that. If that doesn't fix it your Motherboard is likely fried and you will have to replace it

You must push both buttons on the top and bottom of the case all the way in, and then the case will open up like a **** shell. It can be very stiff from the hinge and all the wires.
If you perform a repair install with the Windows XP cd, it should allow you to switch to the English version as it asks you what region/language you want to use during setup. But you should be able to switch to English via the Language bar or the Regional and Language Options Control Panel.

its pretty that you get the service tag or the model number of the system. not the serial number of the monitor.

if not in the cover of the system , maybe you should open the system and find model number in the motherboard. Like dell product ..there is a service tag sticker in the back of the system.
