Click on Start, Run and type in 'regedt32' and press Enter

Expand the "HKEY_LOCAL_MACHINE" key by clicking the "+" next to it.

Expand the "SYSTEM" Key

Expand the "CurrentControlSet" Key

Expand the "Control" Key

Expand the "Class" Key

Look for a key containing the following string of letter and numbers:{4D36E965-E325-11CE-BFC1-08002BE10318}

High light this key by left clicking on it

On the right hand side you are looking for "UpperFilters" and "LowerFilters" under the "Name" column, once you find these Keys delete them by right clicking on them and choosing "delete" exit the registry.

Restart your PC.

Yes you`re probably right cause I`ve seen a file like this.Only I`m no expert with computers,so my solution was to install a fresh OS and everything worked. But I`m quite sure this would be a proper solution cause now there isnt a file like this. Thank you if, a problem reappears I know what to do. I appreciate the help.

I rebuild my PC's every 12 months to remove all of the crap from the Registry for a fresh start. You shouldn't have to worry about anything going wrong for awhile.

If it's an internal Drive then there no drivers required and the Error 39 is referring to the actual Disc in the Drive not the Drive itself.

Generally speaking when this happens either the Optical Drive has died or more likely the Disc that you have placed into the drive is either damaged and unreadable or if it is a Recorded Disc it has the Wrong Dye Type for that Optical Drive to read. Also if it is a Recorded Disc and not been stored correctly the Dye Layer could be corrupted and be unreadable.

You need to check this with a series of Manufactured Media to see if they work and also a series of recorded Disc's. If the drive works correctly with all but this particular Disc you can try cleaning it or you may need to replace the actual Disc.

Of course if the Drive fails to read anything it needs replacing.

All data about drive itself were correct: manufacturer,model,etc.Message said:cannot load device driver(error 39). I wasn`t sure what to do so I reinstalled the OS; and It`s fine now like nothing hapenned. Thank`s for suggestion I really didn`t know what to do at the time.

That error is usually caused by upper and lower filters. Take Jacky Howe's advice and remove filters.

OH Smeg is also correct that internal optical drives do not require additional drivers. They are included in Windows.

Well I didn`t know that,the only thing I`ve changed was a completely fresh copy of SP3,cause a friend of mine told me that might be the problem. SP3 vanished from add/remove panel and then the party started.With this new SP it seems to me that everything works smoother,or is it my imagination? Anyway I saved your tipp incase this junk starts trippin` again Thank`s man!
