Acer Aspire V5-571P-323 video driver problem

i bought my aspire v5-571p touch screen laptop almost a year ago. Because i am technical student i downgrade the original Win 8 Os to Win 7 in order to work with some applications smoothly (software compatability). Since then i couldn't find the appropriate display adapter driver or VGA driver. I have tried all the drivers from acer's and intel's website that are meant to be for the specefied model but none of them seem to provide a solution. I couldn't use softwares that needs graphics support and even the screen becomes blurry(picture attached) if i install one of the drivers from those websites. It works fine with microsoft basic display adapter but that doesn't support to use graphics oriented applications, games and also couldn't control the screen brightness. I have also tried reinstalling Win 8, and even 8.1 but still the problem couldn't be solved. Please help me if you have any idea?
