I would tell you to do exactly what I do, if I find my PC slowing to a
crawl all of a sudden - start the Windows Task Manager (right-click on an
empty area of the Window's Taskbar and choose "Task Manager").
Then click on the "Processes" tab, then click on the "memory usage" column
header to get the items in order - largest down to smallest - so that you
can see at a glance which applications are doing all the unusual hogging of
system resources.
Once you are armed with this information you will be in a much better
position to act or at least look up the effects of the offending
application on the internet.
I would ask you to post your answers here after consulting the Task
Manager.
