My Book World Edition 1

my dad installed this on our network and i tried to access it. automatically, windows 7 tried to install the driver for it so that, obviously, it would work. but, it said something like "installation failed. more parts may be required" or something similar. so i decided to forget it. now, whenever i try to put my comp to sleep or shut it down or restart, it doesnt work, it just says "shutting down" or just a black screen for almost 15 minutes, then goes to a blue screen saying that one or more drivers have installed incorrectly and that something is wrong and stuff like that.

any help would be appreciated...thanks :/

i tried doing the system restore and it didn't work...it just says "preparing to restore your system" and just gets stuck there...last night i tried this and then left my computer after about 30 minutes. i came back this morning and the system wasn't restored to the point i chose, and i think the auto shut off got triggered, and because i cannot turn my computer off, it turned itself back on as if i had never done anything...
thanks a lot, but i think i need to do something else...any other help would be greatly appreciated. thanks

thanks a lot A Guy!!! i cant thank you enough, because, luckily enough, it worked! thanks!!!!
