Champion Select Glitch/Bug Ranked.

I have no video because I do not record my desktop, however when entering solo/duo ranked this evening 10:25 PM EST the champion pool showed nothing. Then when banning selection came around, I was unable to ban any one because once again the screen in. Is this a known bug? Is there any hardware or issues my end that would cause something like this? This cost me a game of my promos not the end of the world but extremely frustrating.
