It may just be over heating. Turn the laptop off. Locate the fan on the bottom, then locate the exhaust. Put your mouth up to the exhaust and blow (like a harmonica). If you get some dust expelled, turn it back on and try your video again.

In the future, make sure your letting the fan breathe. If it's on a bed or soft surface, your basically suffocating the cooling system.

If that doesn't work, let us know.
