Like it happand in patch 5.5, the client frizes up my pc. It's the same now... Patch 6.5 I don't know if this is a coincidence or is riot just making fun of us xD Windows 8.1 Can someone give me an advice or a hand fixing the problem? :D
Ty, for your time GUYS!
Van Darkholme6 votesLike, it hitches and freezes as it's loading the first screen of the client as you log in? I get that too on Win7.
HeyThereTaliyah1 votesFor everyone who still has this problem, I just contacted support and while trying to get a Network Analysis I fixed my problem. I'm not entirely sure what exactly fixed it but it was either updating Java and letting the installer remove any previous Java versions AND/OR activating Java in Internet Explorer via Tools -> Internet Options -> Programs -> Manage Add-Ons -> and then activate Java (for me there were 2 entries which I marked and then activated). After this my freeze was GONE! :)
PS: I'm on Win7 tho.
VAYNE MAIN LUL6 votesWINDOWS 8.1 - HOW TO FIX (WORKED FOR ME) So Whenever I started league of legends (and as a reminder im a 8.1 user) my pc used to froze when I Logged in. So here's what I did to solve this problem. Right Click league of legends icon --> Properties --> Compatibility --> Start this progrem in compatibility mode for: Windows 8. After this u must check that box that says something like : Execute this program as administrator. When u log in, it will froze still. What should u do? You just wait. It took 3 minutes for me, but it can last longer. U just wait and then it will unfreeze and everytime u log onto league it wont freeze anymore. Thumbs up this comment if it Helped you so other people can see. See you in the Fields of justice Summoners :P

xbígÍcestórmáx1 votesThx a lot for ur comment, i had the same problem with 8.1 , and with ur help it does work now.
rukanomi5 votessame thing happening to me. I even tried the repair function and that didn't fix the problem either. Also once I log into the client Alt + tab / task manager wont even come up to help fix this problem. my WHOLE computer freezes up...
Nryk5 votesPlz up vote if you can. let Riot know
Lord Byron 1175 votesI have windows 8.1 and the same thing is happening to me. I would rather give up league than be forced to go through the process of converting to windows 10 so that isn't an option.
HelliKeaton5 votessame here, laptop freezes, task manager doesn´t work. i have even re-downloaded and reinstalled LoL, but the problem stayed the same
Geogaddi4 votesSame thing happening here. Also running Windows 8.1. If anyone finds a solution to the computer crashing problem with patch 6.5, please let me know.
ChaoticBananas4 votesSo does mine. I log in, it starts to load in the main screen, and then it freezes my entire computer.
In2TheRainYires4 votesSame thing here. Bump so Riot can address this issue for Windows 8.1 users.
Rinagi Mai3 votesI have this same problem. Tried a solution found for the same symptoms for the 5.5 patch, but didn't do the trick. (it was to go to properties from the desktop icon, compatibility tab, check run in compatibility mode, select my version of windows, then run as admin. Should've expected failure, since it was apparently an issue with win7 at that time, maybe this time its windows 8 related, but no way I'm downloading windows 10, "when something is free, YOU are the product")
Melinsarius3 votesSame thing happens to me, and I'm on windows 7. The second time ti did it, on reboot my computer forced a CHKDSK command and then it did it a third time (after the command finished) Guess i have to wait a few days to get my

Mr Borg3 votesI have the same issue with my laptop running Windows 10. Desktop works fine.
Nryk2 votesThe same thing is happening here friends. also I have windows 8.1 as well.
I tried reinstalling and running it on windows 8/7 mode. and nothing did the trick.
I might have be hot fixed soon.
Also side note. I can run WoW and Black Light just fine. its only LoL atm. going to try warframes in a bit.
In2TheRainYires2 votesI found a quick work around until the problem is hotfixed. After the client logs in,there is a very brief period in which you can hover over the client. Click the "play" button several times quickly within that period and then wait about 30-40 seconds. (Client still freezes then unfreezes.) Hope this helps guys.
Xaytsr2 votesIn desperate need of a fix for this please T_T I was just sitting at my laptop for like an hour waiting for it to unfreeze...
DosDominus2 votesI'm still confused as to why Rito doesn't see this problem in their testing phases, and if they do why do the release a product that won't work for everyone. At the very least they should put out a statement that their upcoming patches are not 100% compatible with certain windows formats. Idk food for thought rito
Anturaj2 votesSame problem here . Very big issue , could not play any games since the new patch. Still 8.1 win, hp laptop bought 1 month ago, same freeze, task manager dead. Seems like nothing works except upgrading to windows 10 , so nothing really works ! Riot help would be really appreciated. Thanks and good luck ! [slayer-pantheon-thumbs]
JhoiraSeven2 votesThis just started happening with my client, locks down my entire computer, and restarting is not easy on my rig. I'm on Windows 7, has anyone figured out an answer to this?
The Wiener1 votesRight Click League >properties> Compatibility>Run this program in compatibility for Windows 7
And run as admin
Worked for me good luck :)
Arshaka Illithid1 votesNeedless to say, I have the same problem. I also have a solution? I held the power button until my computer went to sleep, and then awoke it, and the screen was unfrozen.

NodaYame1271 votesI had this too right after updating and trying many times.
Chances are it might be a problem that needs to be fixed by riot. But remember...

Im Diving1 votesI've been having similar problems. Except mine happens 10-20 seconds into the match and completely freezes the computer so I end up getting reported for leaving the match cause I can't stay in it longer than a few seconds. This has only started happening today. Idk what to do about it. Only been happening very recently (worked for 3 matches in the afternoon, logged back on around midnight to play a match but wouldn't ever work)
eat sleep farm1 votesi have the same problem and i end up getting reports and ban too for leaving the game. Can you help me?
3TWarrior1 votesI'm wondering if all of these issues might be fixed with the simple answer of right clicking and running league as an administrator as often after patching the privilages of the game are changed for some reason, even though they do not require admin
