I've got a Dell laptop which boots to a black screen with just the mouse pointer.
So far I have run Kaspersky 10 from boot, run CHKDSK, run SFC. I have also checked Explorer.exe is in the correct place in the registry.
Ctl, Alt, Del doesn't work and safe mode is the same.
Very weird thing is it has teamviewer on and when it boots I can see it come up on our monitoring platform, I can teamviewer in but still black screen but I can move the mouse cursor remotely. Also can see shares from another PC. looks like it is working but explorer isn't loaded.
