A few year back I brought a Toshiba Satellite A505-S6005 http://www.toshibadirect.com/td/b2c/retail-product.jsp?poid=460756. Recently when I began playing games (DDO), the display driver always ends up not responding, causing the screen to go black before recovering. This happens from 4 hours into the game to 30 mins, and once it begins it happens very often. Is there anything I can do to find out what is wrong? I did download the latest graphics driver from toshiba (not that it is very recent). Thanks for your help
