I just built a system with an Asus motherboard and a P4 2.8Ghz processor. I installed a Maxtor 30Gb hard drive on the primary IDE and a Hitachi DVD-Rom (master) and Sony DVD-RW (slave) on the secondary IDE. This setup worked fine on my old Dell system. The problem now, whenever I put any type of disc into the Sony, it locks up the computer for about 60 seconds, and won't read it. It shows as working okay in the device manager. I've tried swapping drives around, installed the Sony only as master, same results. I thought maybe the drive was bad, so I installed a Ricoh CD-RW, but it did the same thing. Any suggestions? This is really frustrating!!!
