ACER ASPIRE 4752z laptop screen went white with greyish hue

Hi..Recently when I tried to on my laptop as usual (from hibernating) the display was good. But when I moved my finger acroos the touch pad it freezes (literally freezes with snowy white colour around the edges). After that, it went all white. I force shut down the laptop and try to turn it on. But all there was was a white screen with greyish spots as well as a few fine lines. Then, it turned black but the Window Start Up tune was playing in the background. Is there any tips to fix this problem without sending it to the shop? Please help me because I need my laptop so badly. Thanks!
