I should begin by explaining that I formatted my hard drive about a week ago to fix some annoying problems my computer was having. It was the first time I formatted the hard drive since I first bought my computer 3 years ago. After formatting my hd, I went about installing all the programs I would need, including various applications that help me customize windows, etc.
I know for a fact that after I formatted my hd my cd drivers were working, but I recently discovered that somewhere over the course of the week, they malfunctioned. Now, the device maneger tells me "Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)"
I've tried basically I can imagine to fix this problem. Including following the troubleshoot instructions and manually install the drivers from the internet. So far, nothing has worked, and I really do not want to format my drive again.
Any advice?

I have an HP Pavillion a1330n pc with an ASUS DVD-E616a driver, a TSSTcopr CD/DVDW TS-H552L drive, and the RE5573C VYL933U SCSI CdRom Device isn't responding either.

Thanks
Stan

before i proceed with all those steps, i just want to know what deleting registry entries would do?
should there be any other steps afterwards to replace the registry entries afterwards?
and also, should this "fix" my issue and make my cd drives functional again?
-Stan

If you are careful and you only edit/delete the registry entries specified by Microsoft, you should effect a fix on your CD drive problem.
Not according to those instructions.
