My screen resolution will not save...no matter how many times I change and apply. The screen will first appear normal...than switch to huge icons/fonts. Also, at times, my screen will go totally black...then come back up..sometimes in the larger fonts again and then switch back to normal. But, everytime I turn my computer off, and bring it back up, I'm back to square one again. I've tried everything and nothing helps...it's really getting me down. Thanks for any help you can give me!
