From what Mal has read other people are experiencing the same thing since the last 2 patches happened. Their computers just shut off completely after being in game for a few minutes. WoW won't do anything about it because not enough people are having the issue to make it worth looking into. Many people are simply canceling their accounts until the next big patch happens in hopes that it fixes whatever is causing this. My comp plays everything else just fine. It is a brand new Lenovo laptop and it played WoW just fine for months, then we had an update and ever since then I have not been able to stay in.
