i run vista satellite. i have had this same problem for months. i play games in a site called pogo.com. i mostly play spades and poker, i play for hours and then my computer goes to a blue screen, i get no error messages. this happens 2 to 3 times a day. i have to shut down. when i restart message says shut down to protect data and offers 3 modes to restart. use normal mode. after restart and connect to internet i have several windows of the game room that open. only have problem at this site. tried correcting with help from this site no help so far. i checked problem reports on my computer and found stop or blue screen error reported. any help would be appreciated
