Drivers wont stay installed on PC:(

Hey gues I was hoping someone could help me out here. I just formated my computer and re-installed windows xp pro. Well when I but in my gigabyte MB drivers disk it installed several things, but would not install the usb2.0 drivers untill I got Service Pack2. So now I have sp2 and the usb2.0 install isn't an option anymore. So when I plug in my USB mass storage device I get the message that it will be running slow. I wish this was my only problem, BUT I also noticed in Device Manager There is a yellow ? mark next to "PCI Device", "USB Controller" and "Video Controller" I can get rid of these by updating the drivers by searching through the cd roms but after a reboot it goes back to the way it was. So even when I put in my Display Driver installation cd and install it, nothing is changed after a reboot. Anyone know what the heck is going on here? Thanks so much in advace. :)
