[Game Play] ARAM

I was in the middle of a match, our team was doing stupendous, when all of the sudden, my ping spikes to 10000, then screen freeze's i can't move i can only exit, so i figured, i'll try to reconnect, click "esc" then wait 5 seconds, click exit game, waited a few seconds, then clicked reconnect. Error, cannot connect to server, Exit riot kernel, try to reconnect once more, log in click reconnect not successful. Exit riot once more only this time I can't, black screen. I can't reach my desktop, my internet isn't working, my computer tower starts making a buzzing sound because of hard drive trying to load desktop, so i wait 3 minutes, finally i am at desktop, unplug the ethernet from back of tower, refresh my DNS, log back in. I'm at main menu with match history showing as LEAVE. Bug? you tell me.
