Hello I have a gateway dx 4300-11 desktop with radeon 3200 hd integrated graphics and a glite power 400w psu. I bought a GeForce gt630 gfx card for an upgrade. I uninstalled the ig drivers with device manager shut off the computer, installed the 630 and it has no signal from the 630 but if I plug the VGA back into the ig it displays just fine. The fan spins on the 630 but no signal please help.
