My buddy has a desktop that he build and has had maybe for 3 years. He has two geforce 8600 graphics cards running in SLI and this system has been working since he got it. Recently when he came home he went to turn on his system and it sounded like it was starting up but he never recieved any picture and he noticed both his usb keyboard and mouse both were not powered. SO basically he has a machine that doesn't give a picture and who's usb ports are dead, anyone know what the cause of this could be? We have looked inside and we see no shynging or burn marks to indicated over heating of anything like that. Anyone know a good way to diagnose the problem, could it be the motherboard, graphics cards, port, pci slot? Where should I start the diagnosis.

If the PC turns on and sounds like the fans are spinning, but does not give any beeps of any kind, I would be looking at the motherboard first.

We turned it on but there was not kind of beeps, how would you suggest testing this I mean I dont want him to buy a whole new motherboard with out knowing if his is shot any IDEA's?

Pull your cards
Disconnect the drives
pull the ram

All you want is MB and power and then turn it on.
No beeps its probably a bad board.

If it beeps put one item back at a time and after each item confirm you get a bios beep. If its a bad card or drive doing it, you'll get no beeps when you hook that item back up.

I'd undo the dual card SLI configuration and try with only 1 card, see if you get a signal to the monitor. If not remove that card and try the other.

High end graphics cards can overhead especially when playing really graphic intensive games. it's possible one or both of the cards overheated and the GPU or memory on the card went bad.
