My Laptop( IBM T23 ThinkPad) isn't very well. For no reason or so it seams whenever I move it,even a small distance off my lap for instance,it seams to stop working either the screen fills up with vertical lines or the screen just freezes up, either way I have to crash it to turn it off then back on to get it to work again.

If anybody has an thoughts on this, either whats wrong with it,how to cure it or even if they know a good place to take it to to get it sorted out I would be most greatful.

Any thoughts beautiful people ?
