Anyone else crashing?

Wondering if anyone else has experienced this problem and knows a solution:

So I'm playing ranked for the first few times and haven't had any problems earlier today. However, I play a game now and every minute the game just completely freezes (doesn't crash). All the champs just stop moving but continue to do animations. I can open all my menus just fine. There's not error message or reconnect message. I have to start another client to terminate the frozen one and reconnect to game. After reconnecting I simply get the same problem again after a minute of playing.

Done all the normal computer checking (Yes, I am quite well versed in checking my isp, MAC, ping, looking at system registry, etc) with my firewall history, settings, checking my internet ping, checking my GPU drivers, verifying files for league, etc.

Anyone got any idea?
