I noticed whenever I download via newsgroups I see my CPU usage shoot upwards past 30% up to 50%. It only happens while downloading from newsgroups. I use Newsbin version 5.33. It doesn't happen at any other time. When I'm downloading through my browser all is fine. When I have Newsbin open but not downloading, everything is fine. It only happens once I start downloading with Newsbin. When I go into Resource Monitor, it shows "System Interrupts" as the process that's hogging up the CPU. Could this be a bad driver, if so, how do I find which one?
