CD-ROM NOT BURNING

1. Check your optical drive (cd-rom) physically for faults.
2. Run a disk cleaner for optimum use.
3. Check the software used in burning, that might be causing the problem. If that is the case, uninstall it then reinstall the latest version.
4. Are you using a blank cd/dvd? Maybe not. A cd+-r or dvd+-r can be written only once, even if the burning is not finished to the end and/or not successful. Once the cd is used, it's as good as thrash. CD+-RW and DVD+-RW are rewritables. You can use them until 1000th times.
5. Do a system restore if it helps. Anyway, your files will not be affected by this procedure.
6. Try another software, a different one from what you are used to. Download a free software for burning.

If all fails, check the registry:
1. (XP) Go to Start, select Run, type: regedit, OK
(VISTA) Click Pearl button, type: regedit, OK
2. In Registry Editor Window, select HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/Class
3. Look for the item: {4D36E965-E325-11CE-BCF1-08002BE10318}, highlight this
4. On the right panel, look for LowerFilters and UpperFilters
5. Select individually then delete it from the list
6. Close the entire window, and then restart the pc for changes to take effect.

...to end: count then share your blessings to others...
