Steam Problem, any help would be grand!

[SerenadeShotgun]

okay so, yes this is a problem i am having with STEAM. i just already tried asking steam for help, and still have no answers, so i figured why not ask you guys here.
Okay so this is a weird problem I've had every once and awhile. It's happened before, but gone away, and yeah, I'm really not sure why. It always seems to happen after I play Penumbra or Amnesia; although those are the only games I've played. But anyways, what happens is Steam will be running, and open, I run windows 7, and so on the bottom, on the taskbar Steam will be there. I can even hover my mouse over the icon, and it'll preview a little display of what I should be seeing when i click it. But when i click the icon, it never opens. I've tried ending the program, starting it again, I've tried the repair thing with the installer. and i also ran the repair command prompt, but still I simply can't see anything. So I can't access the store, or my library, or anything. What should I do?
Also: noticed that if i click the little icon in the bottom right for steam, and it displays a little list of what you can open, i can open things like settings, and friends. but anything that opens in the actual steam program like the store, library, will open, but i still can't look at it...
again, i know this isn't really about anything with frictional games, but i'm really out of options here, so any help would be greatly appreciated!
