Bugsplat Upon a period of time after login and random crashes

Okay, so basically when i login to league the client appears to be blank, this would cover where the friends list would be and where the news would usually be aswell. Whenever i fix this by repairing the client I get to play like 1 or 2 games and then the problem occurs again, it eventually gets to the point where i would have to re install the game and start over which I've done atleast 4 times in the pass week or 2. If you guys can reply with a way on how i can fix this I will be thankful
