my desktop pc stop reading discs.. the drive dont show up in my computer and when i put a disc in it keeps spining but dosent play or detects it..please help me!

Restart your computer. Reconnect the drive while your computer is running. Turn on the drive before you turn on your computer. Make sure that there is no disc in the drive when you turn the drive on. If problem still same then you can edit in registry key, but before any editing you should take back up of all registry. Start > Run > regedit > File > Export and save the file in desktop or other drive. Now you can edit this-- Go to HKEY_LOCAL_MACHINE Then SYSTEM Then CURRENT CONTROL SET Then CONTROL Then CLASS Then find {4D36E965-E325-11CE-BFC1-08002BE10318} The whole thing looks like this: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318} Then delete the upper and lower filters.... Restart the computer and then check.
