This morning I was attempting to remove all my ATI related drivers ue to a display driver error I kept getting so that I can start fresh with a clean installation of the ATI video drivers.

The error description are similar: usbs not working after uninstalling AMD Graphics driversĪfter uninstalling my AMD graphics card drivers, the stupid uninstaller messed up my computer and made it so that all my usbs don't work- they work during BIOS, but then stop after that.
