I recently wiped my computer due to a nasty virus. (Dont use AVG as a security system) And i re-installed windows 7 which was easy enough. And for some reason windows 7 had no clue wtf my computer was so i had to take out my hard drive, put it in my friends lap top, install windows, put the hard drive back in my laptop, and configure the drivers for my laptop. It was a process but i did get my laptop up and running. Go to play a league match, queue was fine, champ select was fine, loading the game however i got this error: "An unknown error has occurred and lol cannot start. Please make sure your video card is using the latest videodrivers from the manufacturer." Now i can follow directions, but i cant find anything online this specific so im stuck. Anybody out there have a clue how do debunk this? Thanks
