I honestly can't think of another way to describe these. What happens is that I'll be using Firefox, and then it stops responding. So then I'll type something on MSN and that stops responding. Then I drop to the desktop and try to right-click, and the desktop stops responding. I then click the Start button and the taskbar stops responding. At that point, I can't do anything but wait for everything to respond, and it usually takes something like 10 mins. Through the whole thing, my sidebar gadget is telling me that CPU usage is close to nil and RAM usage is only around 40%. Anybody else seen anything like this?
