SETUPAPI AND DEVOBJ.DLL missing help

[Deepak_23]

I played Battlefield 4 and suddenly it crash and reload. And now it shows that devobj.DLL is missing and sometimes it shows setupapi.DLL missing. Also, I can't open Firefox or chrome from PC. In internet explorer, proxy setting became different. Whenever I try to open Google chrome or Firefox, it says devobj.DLL missing. And in Firefox XPCOM or something missing. Help?!
Edit:I also tried system recovery to the point where I didn't play battlefield 4. Still doesn't work. Tried registry editor by ccleaner. Also checked c drive for error and fixed. Still doesn't work help?!!!!!

I'd do a clean Windows setup at this point.

No! The damned thing won't open an application. It says devobj.DLL missing.

Honestly, I didn't try. How to do that?

Which version of Win - with Win 7 and earlier, simply turn on the Rig, and start tapping the F8 key, it will bring up a text screen with options for booting
