Video or screenshot showing the problem:



osu! version: 20160422

Please try updating/reinstalling your graphics drivers, here are some links:

1. NVIDIA (download the second driver on the list that shows up when you search)
2. AMD
3. Intel

Download and run this file, post the results.

You probably just need to install/reinstall the latest .NET framework. You can go through with it yourself if you're using Windows 7 SP1 or above.

Make sure to run the tool, the new .NET installation and osu! as an Administrator.

my rough guess it’s about a graphic card problem

also check if you had enough memory
