    Morning all.

    I built a computer for my son some time ago. He told me that it stoped working all of a sudden - just poof - not working anymore. I took it apart and gave it a good cleaning. Put it back together and still nothing so I started the diagnostics on it component by component.

    I removed the PSU and shorted the proper leads to start it and check all the leads for the proper voltage. All voltages are correct.

    I removed the processor and put it into another computer. The other computer posted and the processor was recognized but it did not boot up fully.

    I replaced the processor and still no go.

    I then replaced the motherboard and the system is till dead. So figuring that the processor might be bad, I bought a replacement and still nothing.

    New motherboard, new processor, checked out PSU and it is like the computer is not even plugged in. No power what-so-ever, no lights, no fans spinning, nada..... I even tried the on board (motherboard) reset and power switches.

    Before I go out and spend additional monies on a PSU (I don't think it needs one but I only have limited testing abilities - basically checking the voltages only) I though that I would check in here to see if anyone had any other suggestions that I might try.

    Old motherboard: EPOX EP/MF-570SLI/G
    New motherboard: BIOSTAR TA790GX 128M

    Old processor: AMD Athlon 64 X2
    New processor: AMD Phenom II (the new MB support this CPU per their website)

    PSU: COOLER MASTER iGreen Power 500 RS-500-ASAA 500 Watts

    Any suggestions?

    TIA

    Remove the mobo and set it on a safe surface like the box, then connect PS and min HW to get it going...if it boots while disconnected you likely have a grounding issue. Also make sure the PS is min 300 watts.

    The power supply is a 500 watt as indicated.

    It is the PSU though. I was able to obtain another PSU for testing and lo and behold, the computer fires up just fine now.

    Thanks for the input.

    SOLVED.
