Hi everyone, I'm a bit stuck on a matter. I realized that my right fan was making noise, searched online and saw forums that said it could be because some of the drivers are not updated and the fans run at a wrong speed. So, like a fool, I updated my Bios to the last version, and two other drivers in the process. Since then, games are lagging like hell, and downgrading graphics doesn't change anything. The problem is I didn't remember what the two drivers updates were, so I can't undo the update. On the Lenovo Service Bridge website, I wasn't able to find an update history, a driver list, anything that would help me find what needs to be removed exactly.

So I wanted to know if you knew of some way to retrieve said history, or am I just stuck with the "restore everything " option ?

Hi

You do not mention what type of computer and Operating System you have.

Usually you can roll back (that is how it's called) a device driver.

In Device Manager right click and select properties
Click on the Driver Tab and select Roll Back Driver.

If this option is not available -or as in your case you do not remember what drivers you updated...-no driver back up exits, so restoring the system to factory default is your only option.
