I have a psp and its is not working properly, can you help?

Question

it has been acting weird, for example, on star wars battlefront 2 the character moves by its self, they move slower and i cant sprint. also it on the menu it starts moving by itself too. And in the internet browser the arrow moves and moves slower when i move it up and left. I tried taking the battery out as it said omnthe playstation website said, but it did not work. How can i fix it?

Answer 1

It might be dirty. Do a search for cleaning or repairing it.
