Are you using integrated graphics or a discrete graphics card? I'm not sure what tempin1 refers to. But it sounds like the SB 710 south bridge is overheating. That is the chipset that contains the integrated graphics. If that's the case, you may have to replace the heat sync over the chip with a heat sync/fan.http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=100008004%20600035743%20600035748&IsNodeId=1&name=South%20and%20North%20Bridge%20chips
Or perhaps, just remove the existing heat sync, clean the thermal compound off, and replace with new. It may have been a faulty thermal compound installation from the factory.
