This is my 3rd PSP.. and every single one had hit the dust. You know that problem where the buttons keep moving up on their own. Very frustrating. I don't know why this keeps happening. What's going on here? And I tried the tutorial where you clean the buttons. It didn't work.

I just don't get it. This is my 3rd PSP and every single one has run into this problem eventually. Do you know why this always happens?
