I'm no longer able to turn on one of the computers here at work. At first I thought it was a problem with the power supply, so I switched it with one from another working computer and still nothing. (Simultaneously I was able to test the power supply from the broken computer in the other computer and it does in fact work). I noticed that when either power supply is connected to the broken computer, when connecting the keyboard the three lights light up. Could this be a problem with the motherboard?
Thanks in advance for any replies.
