Both in fullscreen and windowed mode? Any mods running? Have you attempted to delete that 1.8 profile and make a new one?
Though I don't believe it to be an issue with Minecraft directly, make sure it's working properly on older patches. Namely 1.5 and below + 1.7. If it works on both, you're good. If not, I'd argue deleting everything in your .minecraft folder except resource/texture packs and saves and reinstalling the game entirely.
Otherwise, check to make sure your minecraft.exe (located in %appdata% and .minecraft for Windows) isn't running in compatibility mode. I don't really know if there's a real solution aside from the above ones unless it's a fullscreen issue. I've got a feeling you'll have to resort to a complete reinstall of Minecraft even if it doesn't happen in 1.5/1.7 (assuming the problem persists). Just don't delete the saves folder or your resource/texture pack folders.
It seems that I can't CLICK anything.
Yes. Not even CLICK the [Single/Multi]Player button. I can't play my favourite server.
And before that, I can't move my inventory stuff with my cursor. I can only hit number buttons (1-9) and move it.
Anyone can help me? :'(

You want these emeralds? Too bad! These are MY emeralds!
I don't care if you have a egg or dragon in your signature. I'm not gonna click it.
