Acer Aspire 9502WSMi Shuts Down When Upper Parts Are Pressed!

I have an Aspire 9502WSMi and it was working properly. One day it just shut down for no reason. It sometimes shuts down when keyboard, palm rest, or even when I try to close the LCD lid. As if like there's something being disconnected when the laptop is touched in a wrong way. This is my first time to have this kind of problem. I have already tried opening the laptop resitted the ATI X700 video card, CPU, Plugs, Battery, and RAM but I still get the same problem. There's no problem if you don't touch the laptop. But again it shuts down once you start pressing the rest palm or keyboards. It doesn't happen all the time. Sometimes it's working fine. Oh and one more thing, the battery status blinks or turns on and off when it happens. There was even a time when I can't get the laptop On even I press on the power button. I have to press down everywhere bend here and there trying to push the right spot. Please help me with my problem. Thanks
