Need help with laptop keyboard

[brandonmcnulty26]

Hi I have a Dell latitude 3540 running Windows 10 and out of the blue the alt key will spaz out and I can't do anything. If I hit the control key it will stop but then I can't type anymore without it pulling up a command.

have u tried reinstalling the keyboard driver?if its still persist try disconnecting the keyboard from the motherboard and reconnect.

Thanks but that still didn't work I honestly think it's because this laptop is like 10 years old that I just need a new one.
