hey i just got done building my first gaming pc with my brother. everything is up and running, except im having a little trouble with my gpu. i have a gigabyte 7970. when i put in the disk to install the drive, i can't click on "install directx9". so i click on install display drives, it brings me to the amd catalyst install manager. it says it finished downloading, but there were errors. im new to this stuff, and have no idea what i am doing. also the gpu's fans aren't working, is that normal? please help.
