Pressing more than 3 keys at once

[Kerry]

A friend has a new Dell computer and everytime he tries
to use more than 3 keys at once the keyboard beeps at him
and doesn't allow it. He's changed his accessibility
options so sticky, filter and toggle shortcuts are turned
off but this hasn't helped. He needs to use lots of keys
at once for when he is playing games on his pc. Can
anyone help?

Usually the keys run independently,arrows and ctrl,the
mouse operates the others,there should be a set-up
option in the game for editing controls.Are the drivers
installed for the keyboard,go to mfg web site and down-
load for xp.
