Hi guys, sometimes steam creates these black boxes when I try to use the library, community, etc...
Also sometimes it randomly crashes.
While firefox has some white lines when I watch something from youtube. If I use chrome this problem does not persist.
I use a Aspire A515-52G. Is something fried or is there still hope?
