tottin7856 - Have a look at the control panel list of installed software on the 'bad' computer for anything that's that's not on the 'good' one that was installed on or after (might have been updated since) Jan 15.
If there is then I'd be more inclined to 'blame' it rather than Dell (not that I'm a fan of Dell or any other 'brand', IMO they're all as bad as one another). Uninstalling such applications won't fix the problem - but I'd be wary, if I had any doubts I'd probably uninstall them.
I'm reticent about piecemeal replacement of dll's, especially those that are part of Windows such as 'Bcp47Langs'.
Rather than using the Windows 8.1 built-in Refresh function, you might want to consider doing this ==>>
Repair Install Windows 8 and 8.1.
The Windows 8 Refresh will remove all application software that's not from the MS Store, which means you have to install and reconfigure everything else.
The Repair Install process will attempt to retain installed all application software and configuration data - my experience (W7 and W8) is that it does a pretty good job -- i.e better than 90%. But before you start. I suggest you backup things like browser profiles, application settings (via screen shots if necessary)...
When you get the system back together with the all the application software working as it should, I suggest you take a system image. I use Macrium Reflect to do this. I've had some negative experiences with other 3rd party products and MS offerings. So far Reflect has always been there if/when I needed it, one of the features I like, is that it can update the image incrementally.
