Today, my computer at work has been acting very slow. There seems to be a lot of lag that occurs between certain operations. For example, when one window has the focus and you click on another window, it's supposed to switch over to it and highlight it instantly. However, there's a slight bit of lag between the switching of focus and I can actually see window being redrawn as it applies the new active window styles. When I maximize windows, it's all chunky-like as it redraws the window to adjust all menus to fit the new maximized state.
I've checked task manager and don't see any processes consuming excessive memory and my CPU is spiking at no higher than 3%.
Are there processes that can be installed that don't show up in the task manager? For example, could my employer have secretly installed some key logger or screen capture software that would obviously not be very secretive if it showed up in the task manager?
I've even rebooted my computer and it's still acting sluggish. It just started today. What can I do to really analyze the usage of my system resources?
Edit: It's a quad core i7 870 @ 2.93ghz w/ 8 gigs of ram.
