I cleaned my computer with compressed air, and when I tried to turn it back on the monitor mouse and keyboard don't seem to work. My microphone (also usb) lights up in any of the ports but my mouse and keyboard don't. My monitor says there is no signal, I tried using the USB port to charge my iPad and it didn't work.
Computer Specs. (Sorry I don't know more)
Alienware R4 Aurora
GeForce GTX gpu
Windows 8.1 64 bit
It has been running fine for about two years so far.

I would wait about an hour and try it again.  You may have sprayed moisture on the components...give it a chance to dry out.

So I waited about 2 days and the USB ports still don't work.

Monitor, mouse, and keyboard are the most basic components of a system.  If there is no indication that there is proper connection between all three and the motherboard...I would be worried.  Without those items, I would have to wonder about the motherboard.

Wouldn't a problem with the mother board cause the computer to not turn on?

Well...I don't think that's a correct assumption by you.

 

Failure by a computer to "turn on" can be the result of various problems, IMO.

 

Failure of any computer function which relates directly to the motherboard (all computer functions) may not necessarily indicate the failure of all computer/motherboard functions.  That's the way that I see it.  USB functions on motherboards used to die fairly routinely...the solution by many of us was to simply install a USB controller card. 

 

As I see it...the mouse and keyboard functions are the most basic which are performed by the motherboard.  I've never experienced a loss of those functions, so I can only guess at possible causes of such.

I haven't got it back yet, but he says it works, and I won't be able to try it until Friday.
