Can My computer still run champions online?

This is a tricky thing and it kicked my one time. Be sure your system meets EVERY requirement. I wasn't able to play a $40 game a few years ago because my graphics card did not support shader model 1.0 and the whole installation failed. And the worst part was that it was a laptop, which means I could not upgrade video cards. My point is, you should probably get a better graphics card which supports a higher shader model (uming you have a desktop). 9 times out of 10, this game will not install properly on your system if you don't upgrade.
