Hello there,
I recently was asked by my kids teacher to repair her computer. Generally I am very good at these things, I spent a lot of time in school and learning by breaking and fixing my own computers for years. Just so you understand that I have already gone thru the standard trouble shooting procedures. Here goes.
This computer did not power up at all. The MoBo light did come on but otherwise the system was dead. None of the fans came on, power LEDS didnt light, nothing. I have seen this before and immediately decided that the MoBo was dead and replaced it (I can get parts at a very reasonable rate), I also replaced the Power supply as its just good practice. Again, I got the light on the MoBo but again got nothing else.
Perturbed, I pulled all the parts. Down to the Front USB cables and checked each one in a system that I have especially set up for this type of parts checking. Every part worked like a champ including the processor. The only thing I couldn’t test was the CPU fan, but I tried to boot without it connected and still got zero response from anything but the MoBo light. I even replaced the case, as I thought perhaps the the front panel pwr switch was faulty. Nothing.
So now I have a system with a new case, Mobo, PwrSupply, cables, everything and its no more along than it was. I am very distressed by this and would very much appreciate any helpful responses.
