Hiya, and welcome to Just Answer!
In order to try to help you, I need to know what kind of issues you are having with your system.
Are you getting error codes?
Do some games work and some not?
Does the machine power on at all?
If it powers on, do you just get a blinking green light?
Has the machine been dropped, kicked, thrown, or other physical shocks?
