the problem usally generates when im useing alot of memory for example when i play a game called knights online it an error comes up which says that the progam needs to shut down....also if im on the internet the send error report or dont send error report error comes up....oh yea in my pc i have a 128mb and another 256mb my 256 is not properly detected by my pc so if i use too much memory it will restart but i dont think that, that is the problem that triggers the error...
