ok i kinda know what i am doing but i want to be 100% i am using my pcs integrated graphics and im getting a nvidian gt 640 video card and all i am really asking is if i plug the new video card in will it auto detect it at start up or do i have to disable my pcs current video drivers and install the new video cards drivers and then restart my computer and then shut down and install the video card
The basic process is:
Install card and screw down the back part
Boot the system
Try both integrated and the new card connected to the monitor because some BIOSes select automatically and some are manual.
If you don't see anything on the new card, then set the BIOS to use PCI-E graphics
