I have a Gateway Windows Vista computer (I believe), and when I got it (~a week ago), it was running insanely fast. My mother installed the printer today, and *bam* instantly everythings somewhat slower. Especially RS. When I click on anything, even the tab to go to it, it takes ~a second to register "Oh, he clicked something!". Rawr, this obviously sucks, since I can't do anything dangerous :s Help, please.

I'm not too sure but you could make sure that the driver was for vista since most of the time they need a completely different driver. Most of the time I think it will just act like your computer is infested with viruses when you install any software that is no compatible. If the driver is not vista compatible then try looking at the printer manufacturers website. If they don't have a driver on their website then you can uninstall the driver and that should solve your problems if is caused because of incompatibility.
