Screen goes black after startup Windows 7

Im having a problem with my laptop...today whens starting after I login into windows 7 the screen goes black...when i try in safe mode the problem doesnt persist...is a software or hardware problem?

 

Did Windows Update install a driver for your graphics chip/card? It sounds like a driver issue or perhaps an unsupported screen resolution problem.

Restart the laptop and instead of safe mode, select the 640x480 low resolution mode. reset your desktop resolution to the recommended one when you get to your desktop.

If that does not work, uninstall the current graphics driver while in safe mode then reboot. Download the newest driver from the manufacturers website and install it then reboot again. You should again be able to set your resolution to the recommended.

 

i tried uninstalling and reinstalling the driver and it works for a day or 2 and then does the same problem again....
