My Dell laptop's keyboard is showing ''gt'' when you type ''g'' when I type ''h'' it shows ''hy'' if I hit backspace it deletes the whole line. I replaced the keyboard, updated the bios, updated Dell drivers, reintalled Windows 7, checked all the number lock buttons, checked to see if it using English, uninstalled keyboard drivers, and removed and reistalled keyboard. I do not have an external keyboard but the on-screen keyboard works fine. I am out of warranty, money, and ideas. Please help. Thanks in advance.
