The other day my laptop acted weird. All of a sudden my screen went black,i could kind of see the screen and i could deffinately still hear the music,so i had to shut it down manually with teh power button,after that its been fine,i did a virus scan and all that fun stuff and cleared out everything. wEll today it seems like the screen is flcikering,i cant tell if its the sunlight just hitting my screen a little or what. its not doing it while i type this,i just turned off my computer for a bit. But if its not my imagination what can I do to fix it?
