Tablet becomes unresponsive after sleep

I'm using a Dell Venue 11 Pro (x86 Windows 8.1 tablet with Atom CPU) and it often becomes unusable after waking from sleep. I'm able to navigate around the Metro/Start screen no problem, but apps won't open. It shows the animation of me clicking on them, but nothing ever comes up. In desktop mode, I can't even get the task manager to come up, or close any open windows or anything. I can see the animation of the x button moving when I click it, but nothing happens

Anyone seen this happen before on other tablets? I haven't used Windows as my daily driver in almost a decade, so what would really help me out is if you guys could suggest some tools that might help me diagnose what's going on.

It's like a service that is required to open programs isn't running anymore or something. It doesn't feel slow or laggy, it just won't open anything. Been meaning to leave taskman running so I can see if it's something maxing the CPU, but I really don't think that's going to be it.....

Thanks for any help!

Hi, Try to follow these steps here:

Reboot your tablet, log in normally and put it to sleep. then wake it up.
Report if problem is still there.

Hmm, seems to have solved it. I'm going to have to slowly start adding things back to my startup and see what was causing it. Thanks for the help!

Hi, good to hear positive results, keep info flowing.
