Can't get monitor out of power save mode

[djfunktion]

I put an ATI Radeon 9600 pro vid card into an old P2 500mhz pc. I keep getting the message..."monitor is in power save mode, activate using pc". Nothing happens when I hit any of the keys. I tried unplugging monitor power cord , restarted pc, re-inserted vid card but nothing. If I put in another vid card (nvidia geforce 2) everything works fine. I do know the Radeon card works cause I tried it in another machine. Any ideas?

That 9600 card may be drawing too much currant for that old system.
