I keep getting something that says my game crashed when I click play on the launcher.

I got minecraft and installed it, but when I click play on the launcher it will close the launcher like how minecraft usually starts. Then the launcher will pop up again and say the game crashed. I've uninstalled and reinstalled the game at least 5 times, but the issue is the same. Also, when I opened the output log one part says this in red.

Couldn't set pixel format

I don't know if I gave enough info. I don't know much about this sort of stuff.
Can somebody let me know how to fix this?
