1/4w would be good. It may burn so get a few extras. Don't do this unless you don't have to go far out of your way to get them.

If we can't find the problem, we may have to do something like item 6 on the Beyond the Basics page.

If you don't have a can of canned air, keyboard cleaner, whatever they call it, pick one up. You'll invert the can and use the liquid to cool the components if we have to go to #6.
