My dvd drive is not recognized by Device Manager/My Computer. Best Buy replaced it, but it's still not working, and I'd rather not have them take it in for another 3 weeks. It still opens/spins, it just doesn't work. I've tried the upper/lower registry fix, all the Windows fixes. Thoughts?

NO MEDIA stated , CD, DVD, Blueray, DVD-r, CD-R, what?
the acid test if it plays DVDs is to use a real store bought DVD movie , that must play, does it? and see the files on it?

The 1millionth post here, with NO OS stated
windows , right? and what version?
click control panel, click system behold version and 32/64 bits.
vista or XP. both are bad news.
XP is dead now, XP cant get MS. PnP drivers now, from mS
they took all that off line 4 years ago, time to upgrade the OS.

here is what it can be: a list.
did the pc get upgraded or downgraded? Windows
Did the HDD get replaced ever?
This PC is only 11 years old , and HP still supports it.
amazing luck there, no?
It came new with Vista 32 or 64 bit, (microsoft ended sport last year)_
so is it still running VISTA, or w7, w8 or w10 via upgrades
(wise to do)

vista 32 bit drivers are here.

load all those but never mess with BIOS. there.
just drivers.

now why it fails, a large list of possible
1: some one up graded it and messed up the drivers.
2: virus infections
3: the drive is bad or needs cleaning,(optics)
4: the HP driver are missing, for it.
5: Disk you are using is bad, or not supported with that optical drive,
5: sure if device manager says its dead, missing red marks or yellow marks or flagged as unknown, the drive is bad or the driver,
drive = harware
Driver = software matching above and the OS unstated by you.

best-buy replaced what, the disk drive optical?

if the PC still has good HDD
power on, and hammer F11 this puts the pc back to day one settings , Vista
and all data lost, and all added Applications gone.

if you had told the OS and told what the label on the DVD drive
says, then a match can be easy but alas you did not.

they must match.

did you right click the DVD drive, and pick update yet?
it will look on local HDD for a driver,
then if missing go to MS and fail , (the pulled the plug there)
leaving only HP support. above,

WoW, that one is a good one.
If you are using Windows OS go to device manager, hardware, uninstall or remove device (DVD player).
Turn off the computer HARD BOOT/Cold Boot, not just reboot.
Start the computer and it should find your DVD add the drivers and install them. That should do it.
NOT all Windows versions are exactly the same, but, once you get to the device manager you should find remove/add devices.
Good Luck
