Do they just run through this process 1 or 2 times? If so that is normal, it part of the boot "check" process, however if it continues after initial boot up, something is odd.  If just during boot up, you may be able to disable in the BIOS configuration by choosing to enable rapid boot or a similar option.

Hi Robwill

it scrolls thru the lights all the way to sign on but i am unable to log on because the keyboard does not respond.  i did try another keyboard also.

Sounds like a motherboard problem. Maybe bad connector? Can you try another type of keyboard? If using a PS/2 switch to a USB or visa-versa. Also make sure in the BIOS, support for the type of keyboard you are using hasn't been disabled.

Where this is probably a hardware issue, you might want to attract the attention of someone more familiar with these issues to get a speedy solution. You can post a 20 point question in the hardware forum pointing to this question.
