Windows 7: driver_power_state_failure

Yesterday and today I came back to my PC to find it frozen on this particular BSOD. This is completely new, and since I know it's related to hardware, the only new hardware that I've recently installed is my graphics tablet:



Yesterday, I attempted to do a livestream and found that when the livestream was recording, my tablet did not have pressure sensitive features. Then I remembered that I hadn't updated my drivers for my tablet for over a year, so I went to their website to download Ver 4.11 of the drivers for my PC. I was currently on 3.33ver drivers.

At first, when I had uninstalled the drivers and put the new ones on, the tablet was horribly mis-calibrated so that the edge of the screen for the tablet was about half the size of the sensor zone of the tablet. As a result, I uninstalled it again and tried putting the old ones back on. Unfortunately, something went wrong and I had 2 MacroKey Manager icons in my systray (MacroKey Manager is a little piece of shortcut software my tablet comes with).
Frustrated, I uninstalled everything I could find to do with the tablet, restarted like 5 times, and reinstalled the new drivers again as freshly as I could. Luckily, they worked!
However, this morning, I noticed my tablet's LED randomly stopped flashing and it stopped responding, as though the power had gone off. To fix this, I had to unplug it and plug it back in. This happened 2 or 3 times, and stopped as long as I was in constant use of the tablet.

I left my PC on while I went out and came back to find the PC in this particular state, and I am sure it's to do with my stupid tablet's new drivers.
There are no files in the minidump folder. What do I do?

EDIT: I have now found from testing that this happens if my computer is shut down. It sits on black screen for about 10 minutes and then goes to a BSOD. the BSOD takes a long time to disappear, and now that I have found that it does, I have a dump file: Attachment 158319
