[HW Problem] Some numbers and left and right keys are not working

Question

Numbers one, two, three, four, eight, nine, zero, left, down, and right arrow keys constantly stop and start working. This also happens in the BIOS. I have to remove the keyboard, the hdd, and do a reboot to get them working.
Device:
Dell Inspiron 1121
Intel Core i3 330UM Processor 1.2GHz
2GB DDR3 RAM
250GB HDD

Is this a hardware problem?

Answer 1

Then I wouldn't think it's to do with the Arch, updating does not stop parts of the keyboard working for the bios as it's separate firmware. When you can access the bios after first turning on, your PC has not yet accessed the hard drive to load the drivers for the operating system yet. Also as far as I'm aware Arch (or any other operating system in fact) has never updated the bios firmware.
