I have the Aspire E15 laptop. This issue happens intermittently. When I turn on the laptop, it boots to the login screen, then when I login it immediately goes to a black screen. I have started in safemode and there is no issue. I have disabled both the Intel and Nvidia graphic drivers and still the issue remains after a reboot. I have upgraded both graphics drivers and the bios to the latest versions and still the issue remains. The previous times this has occurred,if I left the laptop off for a couple of days, when I turn it back on it logs in fine and the desktop and icons are visible. Any suggestions would be appreciated.
