My computer powers up, but my monitor turn to black when it gets to Log on screen. What's wrong?
-
I have sony vaio with Windows 7 upgrade. Often, when I turn my computer on, it powers up like normal. The monitor screen starts like normal until its gets to Log On screen. When it gets to Log on screen, it turns black. Then I would have to press power button on computer once (which turns computer to sleep), then press again 2nd time (which wakes computer up and Log On screen appears). What's the problem? Is there a fix?
