G, There is one thing I do when having trouble with a desktop but may be a bit much for some. Remove the mobo from the case and put it on a table over a few books. Then I connect the bare minimum to it. The vid card, memory, cv/dvd, A-drive, hd and hook up a power supply. Plug in a monitor, keyboard and mouse. From here I try different combinations until I can duplicate the problem. Many hardware problems have been diagnosed using this method. Only my two cents! If you don't like my method, just make believe I didn't send it.

It won't overload if everything is already unplugged/disconnected and it'll tell you if the 400W from your son got fried by the throwing of that 110V switch. If you get the beeps with the old PS connected, you'll know that the owner needs to buy a new, more powerful PS. If you don't get anything "new" with the old PS, you'll know the 400 is more than likely not the problem and that something else somewhere else still isn't right. But, either way, you'll still have your own system still intact. :O) Peace, G http://tinyurl.com/ypbuue "The only dumb questions are the ones we fail to ask!" --------------------------------------------------------------- Please remember to trim your replies (including this sentence and everything below it) and adjust the subject line as necessary.
