Control, Alt and function keys might toggle a screen setting controlled by the BIOS.
So I had major problems with my laptop where it wouldn't startup properly and even going to eRecovery and installing to factory settings wouldn't work. Anyway, I ordered a Windows 7 System Install disk and reinstalled Windows 7 properly on my laptop.
All is working good now except when I turn on (or restart) the splash screen will come up, then 'windows starting' will come up with the little graphic and then it will go all black but I can still hear the tune in the background to say its all loaded ok. Pressing the off button so it turns the laptop off and then pressing it again brings the laptop to the page I was at (only this time not black lol). I've tried pressing ctrl alt del when it's black as well as other keys but it all just works in the background. For example, when the black screen comes up I can type my password and press enter and can hear that its accepted it and gone to my Desktop. Any ideas? I'm using an Acer Aspire 8943G running Win7.
