I was installing a new sound card, while I was installing drivers my pc froze. When i restarted my cd-rom did not show up, or read anything.

I have had a similar problem but i was installing a GFX card. What i did was uninstalled the cd-rom drivers. Then i restarted comp. After that i went to www.adaptec.com and look for their most recent ATAPI drivers.

What to do if XP is Unable to Find Your CD-ROM/DVD/CD-RW Drive While running Windows XP, after having recently installed Burning Software (such as: Roxio Easy CD Creator or Nero), XP becomes unable to find your CD-ROM/DVD/CD-RW drives, give the following a try. First go into the Device Manager (which is found by Right clicking on your My Computer Icon, and selecting Properties. When the System Properties window appears click on the Hardware Tab. In the center of that tabbed page you will see Device Manager. Click on that button). When you see your CD-ROMs or CD-RW's listed, Right click on each device and select Uninstall. Ignore the Warning and remove the devices anyway.) Next go to Start, Run, type in regedit then click OK! In the Registry go to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318} When you double left click on that folder in the Left Window, over in the Right Window you should see either an UpperFilter, LowFilter or both. If either or both are found, right click on those entries and select: Delete. After doing that Reboot and any CD drives that you have will be found, and XP will load a basic driver for your master CD-ROM. This will fix your problem
