I have a HP Pavillion Model XL761 desktop with a bad power supply. It has a Liteon model PS-6161-2H1 power supply. I replaced it with a Micro ATX V200HP power supply. Now I have no video, or I should say, I get a message saying my video adapter is installed and to go to the comtrol panel to configure it. Can't get there. My question, Is the Micro ATX power supply a correct replacement? The HP XL761 has onboard video so the video connector on the PS is not used.
