LoL Will Not Open

Just wanted to report this to possibly help someone who is/will be/or was in my shoes 8 hours ago, so....... I have a Toshiba laptop I play on, I'd click on my LoL and it would pop up like its about to load then crash 0.5 seconds later. It has happened to me about 3 times in the past 6 months of on/off playing. I've fixed each issue thankfully and each one I'v had a different remedy to fix the problem so hope this helps:

1st time resolution: Right click LoL; Click on Open File Location; Click on RADS; Delete Lol Launcher; Reopen LoL- I Ran as Administrator

2nd time resolution: Right click LoL; Click on Troubleshoot Compatibility; Switch to either Windows Vista 2 or Windows XP 2 then ran program

3rd time resolution: As simple as this sounds go into Internet and clear the data/cache in your internet settings. Easiest one and this has been most efficient quick fix.

Also.... Never had to do this but I heard about one user decreasing the resolution of the screen, then trying to reload it and that having positive feedback as well but idk. Anyway hopes this helps some of yall from putting your fist though your computer then throwing it into a tree grinder onto a bed of hot coals, because I can guarantee you that will not fix the problem.
