This sort of problem can also be caused by problems with your graphics drivers or DirectX. It would be worth checking that they up-to-date, as them being outdated could easily create a problem like this:
#HOW TO IDENTIFY YOUR GRAPHICS CARD
- Press [Windows Key] + R (this will open up a "Run" window).
- Type dxdiag and then hit Enter.
- Select the Display tab.
- Note the name and manufacturer of your card in the top left corner of the window.
Most common graphics card manufacturers have a solution that scans your computer and updates drivers automatically. They can be found here:
AMD
NVIDIA
Intel
And visit the Microsoft DirectX page here to make sure DirectX is up-to-date and installed correctly.
Sometimes even if the software is up-to-date, there is some setting throwing it off. Try resetting your graphics software to default and see if it helps:
#NVIDIA CONTROL PANEL
- Right-click on your desktop and select NVIDIA Control Panel.
- Select Manage 3D Settings.
- Click on Restore Defaults.
#CATALYST CONTROL CENTER
- Right-click on your desktop and select Catalyst Control Center (also called VISION center).
- Select Preferences.
- Click on Restore Factory Defaults.
Otherwise, you have really tried every other recommended fix. As such, I'm afraid you would need to send in a Support Ticket for additional help. Before doing so though, make sure to use the Hextech Repair Tool to gather logs, and attach those logs to the ticket. This will give Riot Support all the relevant information about your system, which drastically increases the chance that they can help.
