I have a Pentium D LGA775, with a Intel D945Psn motherboard, ATI x800, 2 gigs of corsair ram, wintv2000. I have had this problem for some time but it seems to happen when ever im opening a video clip or watching something with windows media player. The computer basically freezes, switches to a blue screen gives me the bad_pooler_caller and has a stop:0x000000C2 then following 4 sets of 7 digits strings of number and letters. I looked it up a few times and it says there is some issue with a driver. I dont know if anyone has had this problem before but its kind of annoying. It usually happend every 3 or 4 days.
