All Games Crashing except League of Legends

This is for my friend who isn't exactly tech savvy.
His computer is
I5 2500k Stock clock
8GB G.skill Sniper
Gigabyte z-68a-d3h-b3
Gigabyte 7770
CoolerMaster 700w ExtremePower Plus

Every Steam game crashes usually within minutes and Guild Wars 2 crashes as well. The temps are fine, We have swapped the ram, GPU and hard drives, ran msi kombuster, repaired all the steam files, uninstalled steam. The funny thing is LoL and Borderlands 2 (torrented) do not crash. The games either stop responding or just crash with no notice. Drivers are all up to date along with directx.
I am so lost, I appreciate your help.
