As a side note to the general “try a bunch and see what you like” recommendations: you could also try using a virtual machine (something like Virtualbox) that lets you run a PC inside your existing PC first. That way you can try a bunch of distros without worrying about wiping your existing setup, and it’ll get you used to the install process. If you mess it up, just delete the VM and start a new one, no harm done. Then when you find one you like and feel comfortable with the install process, you can back all your stuff up and do it for real, knowing pretty much what to expect.
