To echo post #2, please provide the exact serial number of your Lenovo E51-80 Laptop.

The only BIOS update that I see listed for it is version 3.08 which was released in April 2017.
I doubt if you can downgrade it to an older version.
Why did you update it?

If your laptop can run long enough without crashing, please do the following in it.
Download and save the tsginfo.exe file.
After it's been downloaded and saved, double-click it to run it.
Information about your laptop will appear.
Return here to your thread, then copy-and-paste the ENTIRE text here.

According to your log in post #4, you have THIS Lenovo E51-80 Machine Type Model 80QB008QSA Laptop

It was purchased in February 2017 in South Africa and appears to have come with Windows 7 64-bit or with Windows 10 64-bit.

The only BIOS update listed at its support site is version 3.08 which was released on April 16, 2017.

Since the older bios'es are no longer available online, you can phone their tech support and ask them for the older versions.
