My Dell Dimension 5150 wont start. I have looked through many forums and found this to be a common problem, stemming from either the motherboard, power supply or front panel I/O switch. I have determined the power supply is okay and now am trying to test the front panel with the power switch, but I can't find any way of testing it. I have absolutely no money, so buying a new one and trying it is not an option. So, if any one knows, please let me know. thanks.
