    Computer Hardware

    System locks periodically and you’ve ruled out software. What helps isolate hardware?

    a)
    Rotate RAM
    b)
    Replace L2 cache
    c)
    Replace all RAM
    d)
    Temporarily disable CPU cache in CMOS

    Explanation

    Disabling cache slows timing and can reveal marginal hardware. If stable with cache off, suspect CPU/motherboard/VRM.
