I have been having this issue as well. I have installed the most recent drivers. (Intel Graphics 530). When I leave my computer for a period of time and then come back to wake the computer up from sleep mode and enter my password both of my monitors (Dual-Monitor Computer Desktop) are displaying White vertical lines with shades of blackish color. I have done a factory reset on my computer and then reinstalled the drivers again. How can I go about installing or updating the BIOS?
