I have windows 10 on a Dell Inspiron N 4010. After installing Windows 10 i have noticed that the screen starts to flicker. But when i connect the system to a projector, no flickering happens on the projected screen, where as the same continues of my laptop screen. Please help. I have tried updating the drivers, taken it to service centres, but no use. The issue does not happen all the time. Some time will be there for months and then stop for another few months . At time screen completely goes dark, and i cannot make out things on the desktop.

Please help
