Initially, when I plugged in my monitor (VGA connection) the monitor did not work, though it did work on my wife's computer.  I emailed tech support, and they recommended that I remove the case, remove each memory stick, and then reinstall them.  This did the trick, and the computer has been running nicely since then (5 days ago).Good value for the money, and tech support was able to get me a resolution to the initial problem that did not involve packing up the machine and mailing it all the way across the country.  I am very pleased with this seller (Bervie Electronics).
