Dell G5 15 Lag after bios update

[Mux78]

Hi

I updated My G5 today as per the system notification which included a BIOS update 

Since the update my machine has been lagging with every task gaming / browsing the net / just in general 

How can I fix this  ?

I'm not a Dell employee, but once you update BIOS, it's pretty hard to go back to an older version. I'd recommend contacting support with your issue, have your service tab available, model and examples of what you're seeing. glen
