Given so little detail, it's new, buggy and rather than suffer repair offers, go for full refund and pick another model.
It freezes during games and streaming video and sometimes when I'm just browsing the web. The games I play are compatible with my computer and operating system and the videos are often just basic youtube videos. Nothing my laptop shouldn't be able to handle. See my youtube video to see what these freezes look like. Any help and explanations would be appreciated.
