Last night I ran a PC Cleanup program on my Acer because someone suggested it would help with my laptop running slow. After running the program I had to restart the computer, and when I did, only the "Windows Starting" screen, then the "Acer Microsoft" screen (green page) came up. When the little green circle starts to boot up the desktop page with all my icons and "start" button on it, the screen goes black. Only the curser is on the screen. After letting it set for a half hour hoping it would eventually come up, the screen saver appears. Someone please help me get my screen back so I can use my laptop! I am borrowing my neighbors computer to post this. I am disabled, and my laptop is my only link to civilization! I cannot afford to pay hundreds of dollars to buy a new one or pay for technical help on here. (Warranty expired 2 months ago) I have an Acer Aspire 7750-6669 laptop.
