Lightroom 6: Using External Drives in USB ports causes freeze up

I installed a new Radeon HD6450 Graphics card on Wednesday.  (Meets specifications as best as I can tell).  Since then, if I plug anything (external hard drive or memory card reader) into any of my 4 USB ports, LR6 freezes up within seconds.  If I try to close LR or click on any another window (Firefox, Photoshop, Task Manager, etc), then the windows start blending together (sorry, don't know how else to say that).  Sometimes I can finally get Task Manager into a full window and end LR.  Other times, I've just had to turn off my computer with the power button.  I tried reinstalling the USB drivers but that didn't help.  I also plugged EDs and card reader into my laptop, and they ran fine with LR6 there.  I have absolutely no idea what to do.  Thanks for any suggestions.

I know it's not of any help, but Radeon (AMD) doesn't have a very good history of their drivers playing nicely. But that's no excuse for LR's behavior either. Are you able to reverse the situation (put your old card back in place) and see if the problem disappears? If you can't do that, try going to the AMD website and getting the latest version of video card drivers for your version of Windows from there. Also, try turning off Graphics Card acceleration in LR. Sorry I wish I could be of more help.

Might be worth unchecking 'Show import dialog when memory card detected' and see if that has any effect.

Since the bad behavior coincided with the installation of the new video card, have you tried removing it and replacing it with the previous card? That would be a good test to see if the USB stability is related to the new card.

Is the video card driver up to date? Did you uninstall the prior card? Having two different cards/drivers can cause major problems.
