    Diagnosing South Bridge (FH82H370) on Asus H370-Pro Gaming Motherboard
    by Ross Kohler
    Hi,

    I'm learning about motherboard repair and I believe I've traced the issue down for the South Bridge on the particular motherboard I'm working on. My path of concluding that:
    - There's no sign of any attempt to power on when pushing the power button.
    - No PSON signal is reaching the 24-pin ATX connector.
    - The Super IO chip is receiving the PS_SWITCH signal from the power button and is relaying this signal back to the South Bridge.
    - The Super IO is not receiving the S_SLPS#_R signal back from the South Bridge
    - If I pull the Super IO S_SLPS#_R pin...

    Metod for removing glued heatsink from fragile component
    by harp
    I have peltir element glued to heatsink with something thick and sticky like putty... it cant be separate with force or heat without risk of breaking ceramic or damaged semiconductor layers due to force (eg if try twisted, pulled, lifted)... method that I am using is a single thread for needle (thin and firm thread of pure polyester that cant break with bare hands without glowes), and using it like a saw between heatsink and peltir. I holding a heatsink with knee against table. It slowly cut throug putty and release glued parts. It is slow proces, but preserve undamaged component and heatsink....

    Seeking Advice on Enhancing Heatsink for Main Processor on SAMSUNG TV Motherboard
    by Ven
    Hello everyone,

    I'm looking to upgrade the heatsink on the main processor of my TV's motherboard for better cooling performance.

    The current heatsink is a square-shaped one (2.8cm x 2.8cn) with a basic design, and I believe a more efficient heatsink could help with thermal management and potentially extend the life of the TV.

    I'd appreciate any advice on the best type of heatsink to use, specific product recommendations, and tips for installation.

    If you've done a similar upgrade, I'd love to hear about your experience and any challenges you...

    KDM 480W PSU upgrade succes! (opinions?)
    by bauto601
    Back in 2020 i bought a (2nd hand) compact ATX psu to replace my current one. My PC case only fits very short ATX power supplies so i didn't really have the choice of buying a decent 80Plus unit. The current unit is a modded YoungYear unit that i made a thread about a while ago:
    A "nice" YoungYear unit? - Badcaps

    The "new" unit is a KDM-M6480 480W psu, the 480W number is a typical KDM bullshit claim of course, but the 24A rating on the 12V rail seemed reasonable and the "Active PFC" claim gave me a bit of hope that this was going to be decent-ish....

    Asus H77 LGA1155 mainboard stopped working with Ivy Bridge CPUs
    by Roman555
    Bad symptoms when Ivy Bridge CPU (3rd-gen 22nm) is installed:
    • Won't boot OS (just blank screen or stucks at asus logo, monitor is turned on) with hangs at debug (post) code A3;
    • USB stick with MS-DOS can be loaded via F8 boot menu;
    • Other OSes won't load - hangs or goes reboot;
    • Postponed for several seconds reaction to Alt-Ctrl-Del, Reset and Power buttons;
    • An operating system starts loading but won't finish if it's left only 1 CPU core in BIOS settings;
    What I've already done and it hasn't helped:
    • Cleared CMOS many times;
    • Flashed different versions of BIOS in a CH341 programmer;
    • Updated
