my problem is that for a few month i had no monitor i just bought one connected it plugged in. i turn on my computer and the regular boot up starts up until the point where the log in screen and all i see is a blank screen(when i say blank i mean black) i can still see the cursor and move it around but nothing else happens
i would restart and go into the safe modes and the same thing happens jus a black screen but with a bigger cursor which is normal. and te last known good configuration does not change anything at all.
how can i fix this?
