WHen you install a new video card and/or RAM do you have to re-register windows?|||no...just install the video card..and use the cd to install the software and drivers if it doesnt detect them itself...and for the RAM just put the DDR RAM on its propper slots..and it automatically will be added next time u restore..ur pc...|||nooooooooo|||nope, just when you replace your mobo.|||not really, you should be able to add other peripherals to computer, but sometimes changing some hardware can cause windows to want to re validate, if anything does occur like blue screen of death, try replacing back to prior hardware to reboot, and then reinstall again ,
