RE: Dell Inspiron 7520 unable to install functional AMD video drivers
I did a quick search on the error "Thread Stuck in Device Driver" and found this forum thread from AMD's website.
One of the things that it comes up that is causing the error is a AMD program called AMD Gaming Evolved. I would check to see if you have AMD Gaming Evolved (raptr) installed and if so uninstall it. Here is another AMD thread with instructions on how to uninstall it.
Please let me know if this helps.
