My screen is flashing white when i open any folder. It will also flash white when i plug anything into the usb ports. I have been using Mr Grims Black theme for Win10 and have had no problem until today. It flashes like this on all themes even Win10 default themes. Ive updated all drivers using Iobot Driver Booster 3 because i cant get into device manager to update that way. Ive ran windows update and it says windows is up to date. Any suggestions on what this flashing white screen is? thanks
