I have a Abit K7 motherboard running an Athlon XP 1700 with 512MB of memory and a TDK 24/12/40 VeloCD CDRW drive. I've been having problems with it since I had to uninstall my Soundblaster Audigy Platinum eX card. My CDRW gets identified by Win XP when I boot, but right after the exact make name appears in the "new hardware" icon, a generic CD-Rom drive is identified and then a yellow exclamation point appears next to it's name in my device manager. When I check the driver, I am given a report that I have a Code 39 error, that my driver is wrong or corrupted. How exactly do I fix this? I've tried uninstalling the driver and repeating the add hardware, but it never works. I've been told I need to edit my registry, but I don't know where exactly in my registry I need to go, or what/how to edit this? If there is a patch, or a little trick someone can tell me to do, it would make my life so much easier. I am a computer novice, so I need extra details. Thank you in advance. -John

use regedit by clicking on start run then type in regedit and click ok then do this it will fix the problem, Use regedit to remove the keys named UpperFilter and LowerFilter from: HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
