Acer laptop-blank screen
I have an Acer laptop. When it is first turned on the screen is blank. The computer was updated to OS-Win 7. I have to turn the computer off and on for several minutes before I can log on. Is there anything that can be done whereas I am able to log
on after turning the computer on and not viewing a blank screen? I have not used this computer much and would love to keep it a little longer.
