Hi, well I got a low profile Ati Radeon HD 4650 card for my Dell c521. I installed it into my computer, got the computer running and everything. I then uninstalled all drivers from my previous Video card. Its integrated with the motherboard (Nvidia 6150 Le), so I cant physically remove it. So I then installed the Ati drivers. But once I connect my monitor to the 4650, it goes blank. However its not blank with the Nvidia card. Why is this happening? I went through the bois and it had these 2 options:
Primary Video
(Auto default)
This setting specifies which video controller is primary when there is two video controllers available. This selection only matters when if there are two video controllers present. When Auto is selected, the add-in video controller will be used.
NOTE: A PCI Express graphics card will override the integrated video controller.
I tried both of them. Nothing seems to work...
I tried it with my Hp slimline it works perfectly and it has a 220W PSU, while the c521 has a 280W PSU.
Im really doubting its the PSU's problem. Somebody PLEASE help me. I am willing to do anything.
