[Client] Logging into client freezes computer

For starters, I'm using Windows 8.1 as my operating system. Whenever I try to log into the League client, my entire computer freezes. I'm able to play other games, use applications, connect to internet, networks, etc. I tried to recreate the incident after a hard reset, and the bug occurs as follows:

1. Open League Launcher via. Desktop Shortcut
2. Launch Client via. "Play" button
3. Type password into log in screen (username already saved)
4. Client begins to load, displays window, IP, RP, and profile picture are visible. However, the news and other panels below are blank squares (as though the content is missing); this is likely because this is the point where the computer is frozen. Mouse cursor does not move, hotkeys do not work, applications cannot be opened.

Additional Note: The League Client was loading and working properly before the recall bug hotfix (roughly 4:00 a.m. EDT this morning).
