Hello everybody.

My friend's computer is having a problem..and i want to help him but i don't know how to :/..
So the problem is his computer during games it completely freezes, the colors of the game go all nuts..and the computer just restarts..i also noticed that using Very High/Max settings in League of Legends makes a difference..if it's very low the problem doesn't happen at all,but if it goes VERY HIGH settings it happens 1min later...and also i think somehow it's connected to the Graphic Card..?Because i updated the Nvidia driver and it did make a difference,but it's still happening a lot!
His PC is...

CPU : Intel i5 3570k
GPU : Nvidia Geforce GTX660
Ram: 4,00GB
OS : Windows 8 6.2

Any solutions??Thanks!
