How to Fix ACPI BIOS Errors After RAM Upgrade and Motherboard Replacement

Select Language:

If you’ve recently upgraded your RAM from 8GB to 16GB and now you’re facing an ACPI BIOS error upon reboot, don’t worry—there are steps you can take to fix the issue. This kind of error often happens when there’s a hardware conflict or a problem with the BIOS recognizing the new memory.

First, try resetting your BIOS settings back to their defaults. To do this:
1. Turn off your computer and unplug it from the power source.
2. Open the case gently and locate the CMOS battery on the motherboard.
3. Carefully remove the CMOS battery, wait for about five minutes, and then put it back in.
4. Close the case, plug your machine back in, and start it up.

If resetting BIOS doesn’t work, check how your RAM modules are installed. Sometimes, simply reseating the RAM can resolve compatibility issues:
1. Turn off your PC and unplug it.
2. Open the case and carefully remove the RAM modules.
3. Place them back into the slots securely, making sure they click in place.
4. Try booting up again.

If your system still doesn’t boot or gives the same error, it might be a compatibility issue with the new RAM. Verify that the memory is compatible with your motherboard:
– Check your motherboard’s RAM specifications.
– Ensure the modules are of the same type and speed recommended by your motherboard manufacturer.

Since your attempts to boot from USB or CD-ROM aren’t working, it suggests the problem might be with hardware or BIOS settings. You can also try updating your BIOS firmware:
– Visit your motherboard manufacturer’s website.
– Download the latest BIOS update.
– Follow their instructions carefully for updating.

If you replaced the motherboard and are still experiencing reboot loops when trying to access recovery options, it could be related to a faulty hardware connection or a corrupted system. In such cases, performing a clean OS reinstall might be necessary, but make sure to back up your data first.

Lastly, if these steps don’t resolve the issue, seek assistance from a professional technician who can examine your hardware more thoroughly. Remember, sometimes hardware incompatibilities or faulty components need hands-on troubleshooting beyond what troubleshooting guides can offer.
