What kind of strange glitches with the laptop?

Question

Iron

The laptop freezes, and a frantic ripple appears on the screen, which can be accompanied by no less wild hiss, or maybe without it, silently. This can happen several times a day, or maybe once a month, somehow it happens randomly. In principle, you can see something on the screen, for example, the Start button, but the laptop does not respond to any actions, and this is treated only by a forced reboot.
To complete the picture, here is a video (an external monitor is connected to the laptop, and I shot it).
Overheating is hardly possible, the last time it happened was tonight, I left the laptop with running torrents and the cooling pad turned on for the night. And vice versa, this has never happened in games, usually when idle or working with office programs.
Notebook Asus k53sc.
OC Windows 7 Ultimate Sp1 x64.
