Device manager empty in W7 64-bit

There was a typical long list until recently, and now they're all gone. I was looking for my scanner which isn't being recognised, although the printer (it's an all-in-one HP photosmart 8180) is recognised and will print. I've run driver updates, registry cleanups, and system restore but with no effect. Ach!

Have you run a scan for malware with Malawarebytes and / or Superantispyware? Otherwise open a command prompt as an administrator and run sfc/ scannow

I have Norton 360; I'm assuming that has it covered. There have been no indications of malware. I wouldn't know how to run a command prompt, unfortunately, but I'll find out if need be. Thank you, John.

Just go to Start / All programmes/ Accessories/ then Right click on Command prompt and select "run as administrator". Then enter. A black box will appear. type in sfc/ scannow (note gap after /) than enter. It should run and check and correct system files. No harm in running SAS (Superantispyware) in spite of Norton.

Just before this, Click on Start, then Right click on "computer" then select "manage" then see what is in device manager.

Thank you John, I'll give this a go tomorrow. There is nothing in device manager at all. I was looking in there for my scanner, that's how I saw it was empty. There had been some conflicts identified earlier which may have been the reason my webcam wasn't being recognised, but that had not been a priority so I left it. Then I wondered if they were affecting the scanner, so I went in to look. Can of worms opened! Another recommendation has been to repair Windows; I'll try your suggestion first though. Thanks again.

Re my former post.(9.04 pm yesterday) correction to type . Should be sfc /SCANNOW - not as above. Note space between sfc and / and upper case SCANNOW. Just tried it. Takes about 10 minutes.

Phew! Thanks for the update - I've been busy so hadn't got round to doing anything yet. Looks like tomorrow again. Cheers

Ran the command prompt and all's clear, so it looks like I might need to repair Windows. Thanks so much for your help.

If the scannow is all clear I would be inclined to telephone the microsoft tech help. They can be quite helpful on such things and may save you a reinstall.
