Last week my ps3 fell on it's side... Now this isn't a case of miss treatment or carelessness... As a serious fact I bumped while cleaning ... I turned my system on and I then noticed funny sounds being made? As If it was in the disk area? I can't install the bf4 dlc second assault either as it always freezes at 93% ( yes I've tried re downloading it but it was a waste of GB of internet usage and my time)

Lately I've noticed it runs slow on black ops2 as in loading levels??? Now what could be the possible case here and if you guys have an idea how much will I have to spend in order to get my system back to performance?

Sorry guys I know this is a modding discussion and it is my mistake but I'm going to be asking on most forums just to get a better understanding...

I just want to say thank you to thoughs who are whiling to assist me in this bad time...
