Okay, this is driving me crazy. Whenever my PC is left idle for some time, CPU usage by "System" will ramp up. I have no idea what is causing it. I had thought that there was something in Task Scheduler that would run itself whenever my system was left alone, but there is nothing of the sort. I've also tried using Process Explorer to get a more in-depth look at what the heck "System" is, but it's as equally vague as what Task Manager is telling me.

Has anyone run into this?

No, I have an Intel board that uses the company's 82579V.

From some Google searches people have had success fixing this issue by updating the drivers. I would start with Intel chipsset drivers. Can you post your setup?
