I have a geovision 8.3 every few hours or sometimes few days the system crashes. when i turn it back on black screen on all cameras for 15 sec. then video lost. If i restart 4-5 times comes back on and starts working. I checked the system log and says DMIPC_FATAL_ER... for each time it crashed can someone help?

i have windows xp professional version 2002 Intel Core2 quad cpu 2.34GHz, 2.00GB of Ram The card and the drivers are legit * After it has crashed sometimes it comes on, on its own and other times comes on with a black screen and then video lost. If i stop all monitiring and restart multicam sometimes it comes on and other times still video lost Thanks for your help
