Pioneer DVD-ROM

I have a problem with my Pioneer 16x DVD-ROM, it freezes my computer to a black screen when installing applications and games, but it works flawlessly when viewing movies or extracting audio to mp3. In order for me to install let’s say Office 2k I need to go into the Device Manager and disable DMA for the drive, after that I can install it without any lockups, then I have to enable DMA to view movies or extract audio at higher speeds. I have pondered for some time with this problem but it is beyond me. So, does anyone have a clue as to what can be causing this? Any help would be greatly appreciated. Thanks

System:

Abit KT7A RAID (not using RAID)
ASUS Geforce 2 MX
Pioneer 16x DVD-ROM (Master on the secondary IDE controller)
IBM 40GB HDD
Sound Blaster Live
512 MB PC133
Windows 98SE

No I didn't have such problems, my only problem is that when DMA is enabled for the drive, I can not install applications, or games without the computer locking up on me......
