During the Boot Camp Assistant (partitioning) process, were you prompted to download a drivers disc and subsequently burn it?
You mentioned that you installed "drivers", but I'm not clear on which ones you used. It's very important that you install the Boot Camp 3.0 or 4.0 drivers, which you should have been prompted to create on a disc during the initial setup of Boot Camp.
OK, so you have the disc. Let's take this step-by-step just to make sure I'm not missing anything....
You boot the machine into Windows and pop the disc in. From there, you'd need to open up the Boot Camp setup program by opening the disc from the 'Computer' window. Did you do that piece? And if so, did it run through setup without encountering issues?
Yes, I did that step without encountering issues. After that it didn't work so I clicked repair button. It didn't repair anything so I burned drivers on another disc again. It still didn't work.
If it did install the software, you should have an 'Apple Software Update' entry in your Start menu. I would try running that next to see if it identifies any updates to the Boot Camp driver package.
I'm wondering if maybe is this update - Boot Camp Software Update 3.2 for Windows 64 bit, right one.
Should I maybe uninstall drivers and try to install them again?
