Datarecovery companies usually gives free diagnostics, if you have important files in your drive i advice you to take it to a data recovery company nearby, if the issue is PCB related, it shouldn't be expensive, i recommend you to get a proper diagnostic before you try anything, maybe the price will change your mind to try anything by yourself.

yes its true i will not try anything some one can point me for a truisted data recovery? i am from puerto rico i can easily send to usa

also need the best trusted hd brand to buy one for my desktop

in your experience can be the board the problem?

It might be a PCB issue, you can send it to datanalyzers in Orlando, about a replacement for your drive i would say to stay away from seagates, WD's are fine but always make a back up.
