Answers :

First of all, keep the front button pressed until the system shuts off. It might be one of several causes:
1) Memory module damaged (or dirty)
2) The processor is damaged, or
3) The motherboard parted off.
Remove the memory modules and test them one by one. Or if you can test them in another PC (assuming both PCs use the same kind of modules).
