I have done a clean reinstall of Windows 11 home but and have done all the updates offered, but still seem to be missing the correct drivers as startup and restart don’t work. I can get to recovery mode, can open windows in safe mode, once in a while it lets me in to windows but never starts up or restarts properly. I looked on this site to download the drivers but it doesn’t work.
The problems began after I did a reset, which wiped out version 23h2, the new install is 24h2.

    i suggest that you do a Clean Install of Win-11 24H2 and all its updates to OS build: 26100.3194 (don't install Win-10 as the i5-1035G1 can run Win-11 which is a better OS) and start from scratch, also make sure that your Aspire C27-962 AIO has the last bios version R02-A2 as this last bios has allot of hardware and firmware fixes.

    Use this AMIUEFIBIOSFlashSOP for Windows PDF guide to flash the bios

    Keep it simple as doing a clean install of Win-11 24H2 should fix all the driver problems. You need to construct a Rufus 4.5 (follow their guide) and do a bootable USB and put the last Win-11 24H2 .ISO file onto that USB, let the install finish and see in device manager if there are any uninstalled drivers. Get back to the community as this install should fix your driver update problems. Good luck.

    See this guide How to flash BIOS from UEFI Bootable USB flash drive and follow this guide and use the appropriate bios files from the C27-962 bios R02-A2 folder. good luck as I can't explain it to you any better.

    the guide was helpful and I could get as far as choosing Flash and hitting enter, then I get this screen

    I went to windows security and turned some stuff off, but am unsure which particular setting is blocking flash bios

    You are starting to see why Acer hasn't released a driver package for Windows 11 on your machine… Windows 11 blocks the amifldrv64.sys driver by default because it's insecure, after all it allows a user to change their BIOS! Since it being used to change your BIOS to a new one, that's expected. :) The BIOS install will work fine in Windows 10, since Microsoft wasn't blocking it then. You can do as you attempted in Windows 11 and remove the driver block, but be sure to turn it back on after the BIOS update.

    Now, having said that, I normally never suggest a BIOS update when you system is unstable. Always fix the instability first, then do the update. Having the system crash during a BIOS update can brick it, requiring a trip to a service center to have it reflashed, and that is never cost effective.

    Thanks for both of your comments, appreciated. The problems with startup and restart began after I did a reset and a clean install of Windows 11 v24h2. Should have never done that reset as it all worked fine before, was running v23h2. I was trying to remove prior owners stuff before passing on. Did multiple clean installs and always same problems. It was a suggestion on this forum that the earlier bios could be the trouble. I have tried so many routes to fix and am at the point where it seems beyond help.
