Black texture on everything. Dissapears at random intervals.

Black textures appear on blocks at random. They donot appear on items,or skins, neither is water or chests, but most everything else appears black. I do not have a way to reproduce this,because I don't have to do anything for it to happen. The textures load normally,then at random everything goes black.except the few I listed. This has happened every time I tried to play 1.7.2 Single Player Survival and Creative. Multiplayer Survival and Creative. It seemed when I selected my default resource pack it reloaded the textures and occasionally they would be fixed for maybe ten seconds, but I don't think that was why they came back. I wish I had a way to reproduce this, but all I have to do is play 1.7.2 for it to happen. Minecraft has been flawless for the last 2 years on my system so this is strange. So I will include screenshots.

I removed all resource packs from my folder this is definitely default. just in case someone wanted to suggest otherwise.
