I've been getting this weird error message whenever I open my PC from sleep or when I try to shut my PC down. An error message appears and, if I don't notice it cuz I shut off my monitor, my PC tries to go into sleep mode in the process of shutting down and crashes windows. It also resets all Wattman settings but only rarely. Kinda annoying.
"(Waiting for) A dummy window

The error first started appearing after upgrading my graphics card from a hd 7850 to a 480. I used the recommended driver uninstaller and followed all the steps to uninstall, then reinstall the graphics driver. The first time the error happened, I had to recover windows and redo all the work I just did. I've tried upgrading my drivers, reinstalling my drivers, rolling back my drivers, using windows drive checker, and using windows registry checker but nothing worked. Windows is updated to the latest version. Next time my PC crashes, I'll upload the dump file. Any ideas?
