  • [SOLVED]820-3437 with a hot CPU. Fan spins once.

    Hi,

    That's my first post on this forum, and having big hopes about it ;-)
    Kidding...

    So I have that 820-3437 board which starts but only get the fan spinning once. Then full blast and I feel that the CPU is getting too fast.
    I've the CPU rail PPVVC_S0_CPU which is a stable 1.78V (I was hoping for a higher voltage by a bad regulator or transistors)

    I would replace the Bios chip or the clock chip but I will check that first.

    However, I have a basic question since I have a few other 820-3437 with burning CPUs... should we assume CPU is dead if it's boiling or is there still hope?

    History, liquid? Inspect corroded resistors/traces around U6100. Also pin 8 of U1950.

      Hi Duke,

      Thanks! It was a broken trace between the quartz and the clock chip.
      3 cycles fan spin restored and board alive now.

      cheers!
