Windows 7: Plug and Play, Audio service, and device manager all not working

Plug and Play, Audio service, and device manager all not working

I have a Home Premium 64bit and about 6 months ago my laptop's audio stopped working. The speaker icon disappeared from the notification bar, but it is still an option under customize, but it only says the audio service is not running. Also the Windows Media Player opens for a few seconds before closing with no errors or any explanation. Just sudden exit. I can't play audio through headphones or online. I've tried to see my devices manager but it comes up blank as if nothing is there and with My Devices and Printers it loads and freezes in place. I've left it up for days before and it never loaded.

I only recently tried to fix it myself because I don't have enough to be overcharged for something simple at a shop. I've gone into the regedit and everything is there. Under services though, the Plug and Play says automatic but it's greyed out and I can't change it, the service status says stopped and when I click start says "windows could not start the Plug and Play service on Local Computer. Error 2: The system cannot find the file specified." When I try to start the Windows Audio under services it says "Windows could not start the Windows Audio service on Local Computer. Error 1068: The dependency service or group failed to start." I've seen from my Googling that all the audio and device manager and based on the Plug and Play and that might be why nothing's working, but I'm completely stuck now.

Thanks for any help.

There are Windows OS problems, more than just the sound is not working. Sadly, I would suspect it will need a complete reinstall. If you want to do this, the first thing to do is back up (copy) all your user data to some external media as it will be lost during the reinstall. Then use the built in Dell PC Restore to restore it to the original factory condition. F8 at power on will allow you to access the Dell PC restore (recovery) and allow you to do the restore.

Another option is to upgrade to Windows 10 (assuming the hardware and what software you use is compatible). This will give you a fresh install, but will not delete any user data.

I was afraid it would come down to a factory reset. Thankfully the laptop never had been used too much file wise. I've tried the back up option under control panel but it says the dependency service or group failed to start. If I factory reset it but take any files I have to a flash drive is it ok without backing it up? Or is there some deep file stuff that needs to be saved?

Just back up your user data - photos, music, letters, etc. No system files, drivers, etc.
