Asus A7N8X-E Deluxe shutting down 12v problem

  1. Hey,
    I have A7N8X-E Deluxe rev. 2.x.x, and I'm having problem. On
    ASUS Probe voltage for 12V is more often then not over 13V. Then when
    it reach 13.56 (High demanding games) computer shuts down. Funny thing
    is that when I open the computer case and use it like that, voltage is
    approximately lower for 0.20-0.30 V and computer is not shutting down
    by itself. My first thought was that it is temperature related, but it
    is not (55*C-62*C with closed case).
    Also I tried changing Graphic card ASUS V9570 TD 256Mb (it had some
    problems of it's own) with NVIDIA GeForce MX 440 AGP 8X (it is only
    temporary solution), and situation is quite similar: 12V voltage is up
    to 13.4V but computer is not shutting down by it self.
    Does anybody knows what is normal 12V voltage, and is this something to
    be concerned with?
    Any ideas,... anybody? Thanks

    55-60* is kind of hot. My processor only gets up to 48* during gaming and idles at 44*. Get some compressed air and blow out the power supply and processor heatsink and fan.

    Some things to check....

    1. Is your power supply adequate? I was having voltage problems until I upgraded from a stock 300 W to a Thermaltake 480W. It cost me about 60 bucks on newegg, but it solved my voltage problems AND it has a second fan blowing right across the CPU's heatsink. The model that I got also has an adjustable fan setting that fits into either an empty 5.25 slot in the front of the PC or a PCI slot in the back. Schweet!!!!

    2. Is your ASUS PC Probe updated? Mine would read all kinds of crazy stuff for my 12 Volt rail. Once I updated to the most recent version, the problem got solved.
