    Acer 4738 install intel HD driver reboot loading win shutdown - need help

    Acer 4738 (no Z nor G)
    DA0ZQ9MB6C0 REV:C

    Not booting into windows or not loading Intel HD driver, no shutdown no matter how long time I leave the laptop powered on.

    Once install the HD driver, reboot and it will shutdown while half way loading windows while still at the win logo splash logo. It can be powered on back immediately.

    Intel i3 HM55 chip

    Tried already:
    Flash bios
    replace HM55 SLGZS
    swap various processor/memory
    Replace all tantalum cap which is slightly low in value 200+uF instead of rated 330
    measure solid cap capacitance still good within value (esr negligible, I am using Atlas ESR70 meter)
    power choke no heatup (0.4 / 0.5 ohm)

    Anyone had come across this symptom or have any ideas to share?

    If not mistaken the HD driver also install Intel HD audio, can anyone confirm?

    Thanks in advance

      Why the hell did you do all that

      Please put back 330uf capacitors...Don`t play with that power rail...first...you have replaced or reballed PCH,so if you have replaced it you must update bios with clear ME region... symptoms you have may be caused by that... Second after proper flashing,if doesn`t work try replacing cpu...
      After that we will diagnose it further...

              LED DRIVER KEEPS DYING
              by osrex
              Hello, this is my first post and im just a beginner, so be easy on me guy. thanks



              i have a LED chandeilier that switches colors from white to cool white to warm when toggling the switch, it has 24 LED arms, each arm is 30 CM length.



              i have no datasheet at all for the LED lights, all i have is its length.



              long story short, testing the chandelier on the ground, and it works fine for 1 - 2 - 6 hours, no problem.



              as soon as i fix the chandelier to the ceiling and bury the driver inside the hub,...

              Vizio TV M50-C1 reboot cycle and static on screen
              by spice_disc
              I'm currently trying to diagnose and fix my Vizio TV (Model M50-C1). I've tried a number of different basic solutions, but I'm trying to determine if my issue is currently a failing panel, T-Con board, or main board (or something else entirely) and whether or not it is worth my time to fix it. Details of the issue and what I've tried are below as well as why I think it is either a bad panel, T-Con board, or main board.

              The Issue: The TV will be on and working fine but after the TV is on for ~5-10 minutes the screen will freeze (with sound continuing) until the TV reboots itself. While...

              Vizio E55-F1 dark backlight zones. LED failure or Dimming Zone Driver?
              by howardc64
              Problem

              Fixing a dimming zone TV with LEDs not lighting up. Dimming zone circuit introduces added variable to diagnose LED and/or Dimming Zone Driver board? Some 1/2 rows of LEDs appears to be out in active dimming zone off AND some brightness flickering with active dimming zone high while playing changing video



              Model & Board Pics



              Conflicting Spec

              Vizio indicate this TV has 10 dimming zones. However, LED strips and Zoned light driver connector suggest 12

              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
              ...

              Audio Driver for Thomson P14C4BK128
              by charif
              Need Audio Driver for Thomson P14C4BK128 (Windows 10/11)

              Hi everyone,

              I'm looking for help finding the correct audio driver for my Thomson P14C4BK128 laptop.
              The sound is not working properly, and I believe the audio driver is missing or not installed correctly.

              Here are the details:
              • Model: Thomson P14C4BK128
              • Operating System: Windows 10 64-bit

              If anyone has a working link to the driver or knows where I can download it, I'd really appreciate it.

              Thanks in advance for your help!
