Graphical Bug

I have a problem with my minecraft(bought and downloaded very recent) where I start a new world and everything would seem fine up until I destroyed a torch near a chest and everything disappeared except lava, water, chests, and mobs however the blocks were still there acting as barriers but still remained invisible. I tried it a second time destroyed a dirt block still happened quit and uninstalled and re installed minecraft destroyed a tree still happened but i can destroy grass and flowers.
