[QUOTE=rago88;2625253]1 question about installing a new video card.
is it necessary to go into your device mngr and un-install the old one before shutting down your PC for removal?[/QUOTE]
Yes it is recommended to unistall the driver for the graphic card you are removing first before you turn off your system to remove the card, I suggest you locate the latest driver for the graphic card you will be installing and download it to your desktop prior to turning off the system.
After installing the new graphic card and start the system most likely windows will install a driver for the new device, you can cancel the process if you have the option but I suggest wait until it does and just install the driver you had downloaded prior to shut down.
