ok well after i installed my ati radeon x800 pro i tried turning on my computer but i got no picture on my monitor. I took it out and tried again following all the directions in the manual but i still get nothing. it's been like this for three days and im getting really pissed with it. i've been wanting to get my new custom computer up and running but the video card isn't letting me. i have no itegrated video on my motherboard so i know it can't be because og that. if u guys have any idea to why it wont work for me please tell me.
