I've a problem with my new HTPC that I've never seen before. On a couple of occasions now after it's been on and used for some time the thing's become unresponsive .. and on investigation I've found a process called SYSTEM is using 100% processor. Normally it sits on 0-1% on all machines I've looked at, but something is doing something on my HTPC to kick it into life, the only 'fix' is to reboot it. Does anyone know what this process does and perhaps what could provoke it to go into an apparent infinite loop? BTW, it's "System" not "System Idle Process", which I know sits at 99% much of the time .
