Satellite A660-10W - After Windows 7 installation some unknown devices

Question

So I have the Satellite A660-10W, and I reinstalled the Windows 7 it came with Windows 7 ultimate 64bit. First thing is when I use fn+F6/F7 (other combinations work) for brightness levels it doesn`t work, brightness doesn`t change. And the other thing is that there seem to be some unknown devices.
Here is everything hope someone can think of what could it be, thanks in advance. :)

Answer 1

OK you and my friend are right, because I installed the video card drivers from nvidia`s website, not from toshiba, now brightness works :D
And I reinstalled Windows because one thing there were no partitions only one lonely drive and I wanted 30-40gigs for windows and the rest for stuff, not when I decide do reinstall lets say a year later with work and media on it to lose everything. I didn`t do any back ups, even all the shop assistant talked about when I bought it was to buy some dvd`s and backup, but I said I never did that before so why would I need it now, anyway now everything works perfectly, iI`m prepared for the next time :D , thanks for the help. :)
