Make sure you have all updates installed on your computer. Make sure that all of your drivers are up to date. Is it league specific or is it with any game? If it's league specific it could be something got corrupted in the client files themselves. Also make sure your computer is dusted, that can cause things to fail as well. If you are using a laptop, make sure that the vents can get air in them.
When people give "solutions" to freezing computers as "update your drivers and make sure all updates are installed" ... come on, we both know that never actually works. That works if you have a decent computer, but a few glitches here and there. I'm assuming this guy has his computer freeze 24/7 every time he plays league. Seems more of a slow/full hard drive issue. You need to upgrade your PC, baby steps.
