Last weekend, I installed Window 10 on my new Lenovo 500s- 14ISK ideapad. But when I leave it on and doesn't use it for about 30 min or so.. the screen turns dark and shows sometimes white screen with red black vertical lines (when I left the video clip played on and didn't use it for about 30 minutes or so) and today, after working on the MS Word file and left it for more than 30 minutes, it showed me black screen with a bit of noise on top and when I tried to type something.. it showed me similar white screen with vertical red and black lines. This computer is brand new and Lenovo is notorious for its bad customer service. I don't know what I should do. Do you think it's simply a driver problem? (but I installed the most recent driver from LEnovo's site) Thank you!
