    I am helping my brother-in-law with a PC problem. He has a PC who has
    worked fine for about 4-5 years. Now the PC won't start. After hitting
    the power button, there is a short beep then a long beep (CD drive
    lights are on, fans are on, but no keyboard lights), and it shuts off.
    It is a Soyo Dragon motherboard with Phoenix BIOS D686. I Googled the
    beep codes but didn't find this short then long beep combo. Checked
    the CPU fan connection to CPU Fan1, cleared the CMOS battery, no
    results. Should I try a new CPU fan, or is the motherboard dead ?
    Suggestions ?

  3. Does the cpu fan actually spin (keep the cover open to look at)?
    Can you somehow manage to access the bios setup screen?
    Watch for bulged capacitors around the cpu as well.

    Next step would be trying another powersupply.
