Do you get any errors? Do you get a crying Pippi? If so click her and paste the crash contents here. If it just disappears or gives a basic Windows error. Check event viewer for any error logs.

I have crying Pippi. She says :

Make sure your Graphics Drivers are properly installed and updated.

Mind posting your specs?

If updating your drivers don't help. Go into your osu!.pcname.cfg and change CompatibilityContext to 1, save then try.
You can edit CFG files with Notepad, just select it if windows asks.

Make sure you are running 32 bit colors?

If your Drivers are updated and not even Compatibility mode works, and you're running 32 bit color depth. I can only imagine your Graphics is just too low spec.

Ah ! I was running 16bits colors ! Thanks
