P3450 shuts down

[7EtiC]

My Htc shuts down intermittently.
The only solution to power-on is to remove the battery and place it back. It boots, works for 2-3 minutes and then it just freezes. Sometimes stays like this, with the lcd on, or just shuts down.
What can I do? I read on a forum(don't remember the forum, it was some time ago) that it can be a problem from the factory, and a small piece of plastic placed on the processor can fix this.
I must specify that this problem comes after i dropped my device, so the factory problem...i don't know...just don't wanna know that I'm responsible for this. :o
Have a good day.

yup, that plastic thing can be a problem, but there is another thing you can try, in your back battery compartment, add some tissue on the top of the battery (to prevent the battery from falling off), and close it with the htc cover.
