    acer 7520g no boot after bios post

    acer aspire 7520g:
    (I don't know well amd system)
    I can enter to bios, modify boot option, etc but after bios post , the system remain with cursor blink and no boot even with a usb boot pen or cd rom.
    I reprogram the bios
    and removed all unnecessary peripherals but the issue persist.

          after I removed that chip, the system behaviour is correct , I have not time to replace it but i think the culprit is NVIDIA MCP67 a common issue on these boards.

              Asus ROG Ally X -RC72LA - changed hidden bios settings with 'Smokeless-UMAF', won't get past boot logo

              Model No: RC72LA
              Serial No: SBNVKD001014459

              Hi all, I've spent the past week digging through the forums and guides to try correct my foolish mistake of changing hidden settings while tinkering around, and to be honest my heads overloaded so I'm hoping you'll be able to help.

              I used a tool called 'Smokeless-UMAF' to access usually hidden settings in the bios. I tweaked one or two 'safe' things but made the mistake of tweaking a lot of settings under 'USB/Thunderbolt Configurations' when I didn't know what they did. For...

              Hi, I have a few of these & they came with a custom bios boot logo, no passwords etc.

              2 x were brand new unused but with custom boot logo, 1 I installed Windows/ran updates then it bricked itself. 1 wouldn't get past the custom bios boot logo.

              The third I loaded windows, took a backup of the bios chip, then tried to flash several different clean bios's via programmer which all caused it to not boot. I tried to reflash the original bios both using clip & desoldering but...

              ACER Aspire 5542 does not boot. Can not read BIOS on the motherboard
              by fluzocapacitor
              Hi,

              I am trying to fix an Acer Aspire 5542. Upon turning it on, the fan starts to spin for a few seconds and then it stops. I hear no beeps from the speaker. I have no image both on the laptop screen and through VGA and HDMI connectors.

              I measured voltages, and it seems all power supplies are OK. There are 5V, 3.3V (BIOS), 1.8V (RAM), and 1.1V (VCORE).

              I tried to read the BIOS using a CH341A programmer, but it did not detect the chip. I took the BIOS chip away from the motherboard, and then the CH341A detected the chip, and I was able to read the code. However,...
