CLIENT LAG I DID EVERYTHING STILL LAG

[sg-janna] **So, the client was doing okay until the next day (THURSDAY/FRIDAY), When I open my client it became reaaally slow, It takes forever switch between parties, join parties, click on home/profile/colleciton etc. even picking a champion and joining the in game. Like, It takes awhile before the loading screen pops out. til now it's still like this. **

I tried everything such as:

1. Re-installing,
2. open as admin,
3. Hextech Repair tool,
4. The Firewall thing,
5. SENT A TICKET TO THE TECH SUPPORT ** EVERYTHING**

I asked a friend of mine if he's having the same problem as mine, and he said he got the same problem as mine too same day as me. He can't even play with his team at the exact time the start the game, SAME AS ME. I was level 1 while my team are level 8-9 and I sent a ticket too. I hope this thread will get noticed by the riot techs or whoever. like literally after patch 9.23** *
