I have a dim 8100 1.4 santa cruz nvidia 32, and once in a while , randomly while playing need for speed.. it freezes.. I have to power off and reboot.. I posted this in software other and received no responses.. I was wondering if anyone else experienced this.. I have the det 3 drivers. Also MDk froze up on me once too... I don't know if this is a sound , video , game software , or other problem. I searched for an update for need for speed and found nothing. I am still running the 7.1 DX. Thanks for any replies..
