pretty strange, your your computer will stall but not on WOW. hmm....if you havent done this yet try scanning your computer for any spywares and viruses and see if you got any.
also check the eventlog for any errors and see if the computer post any errors. if there is an error post it and we will all see what we can do to help you out. to get to the eventlog, right click on my computer -> click on manage -> and click on the eventviewer. then double click applications and look for any "X" marks which incidates an error.
hmmm.......do you have a spare power supply that fits on the barebone to test?
