hey, i literally shut the door on my computer (a little harder than normal) and it froze, and now it wont start up. when i turn on the PC is just beeps once about every second. anyone know what wires might have come loose? which ones have a tendancy to do so? or what has to be loose if i dont even see a boot screen?

What is the make & model & # of the computer?

Depending on your BIOS type the beep pattern should point out the problem.
