Not sure if this is a HT problem and not sure if this is the right forum for this but here goes:
I have had instances where my system will start to shut down during game play. The screen goes to black and the last 2 seconds of sound I heard goes into loop. This has been infrequent in the past so I never worried about it. Since down loading the patch yesterday I can stay up and running for only a few minutes now. I have updated my AV to recognize HTC. I have loaded the latest Vid drivers from Invidia. I don't think the CPU is shutting down from heat (runs at 123F). My guess is compatibility issues with the Vid card. New card about a year ago and this problem seems to have begun sometime after the new CPU and vid card install although not right away. May not be related to either????  I will include my system and vid info for anyone who would care to help me out with this one. Many thanks:
