Freeze / Sound Stutter during League of Legends

[Kaeor]

You can read everything I've currently went through here.

I'm trying to find if there's a solution to a freezing problem I've been having. I really didn't have this problem before and the such, it just randomly occurred one day like a few weeks ago. I made one thread about it but I'm hoping to fix/discover more about getting a solution to this problem and was recommended to post here.

Problem:

I'm having a problem with League of Legends that I didn't usually have. But I came play the game for a few hours and get a few matches in, that is, until mid-game and then it freezes and the sound stutters/loops endlessly. It's pretty much like 0:16 - 0:19 in this video. The only difference being the problem doesn't fix itself, it just stays frozen w/ the suttering sound and I have to manually reset my computer. From that point on I'm able to play League for a few hours before the same problem occurs again.

I've attached a dxdiag that contains my computer information. Hopefully someone can help me fix this.
