I have an Intel MB D875PBZ W/P4 3.2 Extreme CPU, 1GIG DDR400 System RAM, Ultra 780 XP GeForce FX 5600 w/256MB DDR, 2-120GIG SATA RAID NTFS, 30GIG IDE FAT32, 40GIG IDE NTFS, 52X IDE CD, MSI DR8-A DVD, 2 NIC'S (ONE ON MB), Creative SB Audigy LS. I have a problem swapping CD's or DVD's, sometimes it will lock up when I insert a CD the first time, but it allways locks after the third swap. ?????
