I just finished building my first computer, and was installing XP. popped the cd into the tray, and was told by windows I didn't have a hard drive. Little did I know that Windows and SATA drives don't get along to well at first, however I dind't know this at the time, and thought it was a cable loose or something, so I took the CD out, turned the computer off, but left the CD tray open...when I turned it back on and put the CD back into the tray and got the CD back in, nothing happened, the light turns on...and stays on, and I hear the disc inside whirring, but nothing comes up. Any ideas?
