Recheck all your cables are plugged in properly. When you say you could still hear the computer do you mean the fans? or the windows boot up chimes?

 

[palmtri]

yes i think it is the fans only

Did you recheck the cables were in the correct place? Ensure non of the pins are bent or broken.

Your friend didn't unplug the hard drive while the computer was on did he? Do you hear the beep from your motherbaord or is it absolutely just fan noise that you are hearing. If your computer isn't even posting then there is most likely either something critical not pluged in or something has been damaged and or is not functioning right.
