screen turns black, and jumps blue,grey,magenta,
When turning on Windows, after main screen pops up, it turns black for a few seconds, then screen turns fully grey, magenta, pink, blue and again, and again..
Laptop works in safe mode ok, sometimes after working in this mode, next time I use it works fine.
But usually it doesnt work even after safe mode.
Please. I´d like to know if it is hard or soft problem.tks
