I just got basically a fully-parted rig from a friend. It contains a Q9650, EP45-UD3P rev 1.0, 4gbs of ram, 250 gb hard drive. I have the PSU from RMA. I downloaded the SATA drivers off of Gigabyte's website after I found out that everything was working. Unfortunately installing the drivers during W7 installation did not make it recognize the hard drive. I've tried going on SETUP and loading the optimized defaults. No luck. I'm pretty sure the hard drive is not dead because during the boot screen, it could read the hard drive as WD 250gb drive. I've tried googling the solutions but some of them were just the ones I've tried. I didn't think I would have a hard time because I had the same problem on my main rig that I'm using right now, I loaded the drivers I got from ASUS during W7 installation and boom, it reads the hard drive.
