Opening Client Freeze [Crash]

Upon Opening League, the login screen runs fine and with no issues. Once I log in however, the main page loads the borders and text, but the main images fail to load. Following that, the application itself will freeze up, which then proceeds to forcefully Freeze up my computer. This is before I've clicked, or performed any action other than logging in. There is no way for me to get out of the frozen screen and I have to forcefully shut off my laptop each time I open it. I reinstalled League, and the first time opening it, it worked fine, but the images were still missing from the front page. The next time I logged in however, the complete Freeze it caused me before would happen every time I opened it.

Rito, please look into this! I want to be able to play again!!! D;
