Hi, My sons PC has developed an issue, it loads to bios ok but as soon as it tries to boot it says auto sys repair then shuts off in a loop. I've replaced the GPU (RTX4060), RAM and SSD one at a time from a working PC but still same issue which leads me to believe a motherboard problem.

Does anyone know which MB I can get to replace it? I think the current board is B76H6-AD but I cant find these anywhere

Specs are i5 13400F, RTX4060, 16gb RAM

    First try to repair this "auto sys repair" which is an automatic repair loop, which can be quite frustrating. Here are a few methods you can try to fix this issue:

    1. Restart Your PC: Sometimes, a simple restart can fix the issue. Long press the power button until your desktop turns off, then press it again to turn it on.
    2. Safe Mode: Boot your computer into Safe Mode. From there, you can troubleshoot and fix potential issues. Here's how:
      • Restart your PC. When you get to the sign-in screen, hold the Shift key down while you select 'Power' > 'Restart'.
      • After your PC restarts to the 'Choose an option' screen, select 'Troubleshoot' > 'Advanced options' > 'Startup Settings' > 'Restart'.
      • After your PC restarts, you'll see a list of options. Select 4 or F4 to start your PC in Safe Mode.
    3. System Restore: Use System Restore to revert your computer back to a point when it was working correctly. If you've enabled System Protection, Windows will create restore points automatically. From the 'Choose an option' screen (as in the Safe Mode method), select 'System Restore' and follow the prompts.
    4. Reset Your PC: If none of the above methods work, you can try resetting your PC. This will reinstall Windows, either keeping your personal files intact or removing everything, depending on your choice. From the 'Choose an option' screen, select 'Reset this PC'.
    5. Do a total Clean Install of Win-11 24H2 and all the updated to OS build: 26100.3775, make sure that you construct a bootable USB with Rufus 4.6 and follow their guide of how to do this bootable USB, then put the N50-650 IRST (Intel® Rapid Storage Technology) Driver version 20.0.0.1037 on the bootable installation USB so that you can continue the installation and the M.2 SSD boot drive is recognized.
    6. Afterwards your N50-650 desktop should NOT have the "auto sys repair" loop.

    If all the above doesn't fix this loop and/or fix your system then the Nitro N50-650 oem Acer mainboard is the below mainboard, search for this board with the highlighted Acer part number shown below.
