so i had my new rig up and running fine for a few days now and decided to get a new SATA 320 GB 7200 RPM HDD 16 mb and i connected it properly (power connector to drive and SATA connector to mobo) I started up my comp and itbooted up fine from my old HD that is a temp for now(20 gigs). I installed the software that came with the new HD and it prompted me to restart. I restarted and now my computer won't boot, actually my LCD monitor won't pick up the signal it switches from "analog" to "digital" and never locks in. I don't think the monitor is at fault since it was just working. Any ideas?
