LOL keeps freezing my comp, is only program that has ever managed to do so....

So I guess I am done with LOL maybe permanently. One in eight games freezes my entire computer. Only program to have ever made my comp freeze like this.... I wonder why? Lol is such a basic program and I often run at 140+ fps.... But every once in a while LOL decides that it wants to make me hard reset my comp... Well I have had enough of that so I am done with this, virus?
