I've been having a problem with my DVDrw drive (HP DVD 740r) - nothing happens when a CD/DVD is inserted, and when looking in device manager I get a Code 19 error (Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged.). I've tried uninstalling/reinstalling, and I get a message saying the driver's up to date but the device still won't function. I've also tried the fix suggested elsewhere on this forum of deleting the upper/lower filters, which hasn't done anything at all. It's quite an old computer (and drive), but has Windows 7 now, which was put on a few months ago. The drive worked absolutely fine until yesterday, when nothing at all changed with my computer in terms of programs or updates.
I've tried locating firmware on HP's website but with absolutely no luck - there don't appear to be any firmware updates (or any downloads at all) for this drive and Windows 7.
ANY help at all would be massively appreciated, even if it's to say that I simply need a new drive. Thanks very much!
