certian keys on keyboard dont work

[Jon Sas]

Some of my keys only responded if i held them down long, ghe, but now they dont work at all and took w fn and 2 with them. Now its also a happening to my backspace and enter. A few weeks ago they worked but now they only sometimes work or never work. My usb board words fine. The keys around backspace and enter are also getting this problem now.

Try removing the keyboard driver, reboot the computer and then let it install a new one. See if this resolves it. If not, and you say an external one works just fine, then you may need to replace the keyboard.
