You're not being specific enough. 

Do you have a laptop or a desktop?

What do you mean by "close"?

Can we have your system specifications also?

What were you doing beforehand when the system worked?

Were there any special occasions that you want to point out?

Most important tech support question, the amount of people who suddenly hang up after being asked that would amaze you.

 

EDIT: Make sure all your connections are good and tight.

You probably left something unplugged. Check back inside again.

If you must, you should disassemble and assemble everything back again.

If that doesn't work, I'm suspecting that you broke a part somehow. 

It's likely you short circuited your board or some other part. 

What were the work conditions like?
