It's my first time to post here . I hope anyone can help me. My screen starts to show streaks of red after playing games for about 15min. Sometimes just streaks and sometimes it turns to whole red. It does not happen before. But after i cleaned my fan it started happening. I'm playing DOW: Chaos Rising on ultra setting to be specific. My laptop model is G75vw-bbk5 and I got it from best buy. It really performs well before. But after I cleaned my fan that stuff with the screen started happening. And no Ican't return it to best buy because I'm not from the US. Thanks in advance!
