I load FSX, LINDA starts, default aircraft/airport load, then the RealAir Duke is loaded C&D. I get it ready to taxi, put on the brakes and then start the tracer.Almost 50% of the time everything works as it should, but otherwise the monitor goes black and the computer reboots. This is the only situation in which the PC restarts. Is it the tracer or some conflict between the tracer and the Duke B60? It usually occurs after getting to the stage of identifying the LVars code for a switch or button.I am determined to learn how to set up my MCP for the Duke but it is frustrating having to restart the project time after time.Any help appreciatedOOPS... I meant LINDA TRACER

ooops, that sounds really strange ...But all in all I doubt that this is related to LINDA tracer.Nevertheless you say it just happens with the tracer and not under other circumstances.Have you ever looked into your system events if windows is showing any error after a fresh restart?And what do you do to trace the LVars?Do you click "start all" (or selecting all) for tracing the LVars?if so, this could be indeed an operation where your computer gets maxed out.And then, you have an overheating problem or RAM problem maybe...Have you ever tested your PC with Prime95??Here is a tutorial how to use it:http://www.sevenforums.com/tutorials/100352-hardware-stress-test-prime95.htmlRun this and maybe your PC will shut down also ...Then we know, you have a problem ...Günter
