Thanks for your help Mike.I am probably a hopeless klutz.I went to the dell site and entered my service tag and they correctly identified my puter.I selected the driver I wanted and hit download.What I got was something different.Its called "dell download manager".When I try to open it my puter says it doesnt know what program to open it with.It directs me to a microsoft site to down load something called net framework.then it tells me net framework will not instal because I dont have something else installed. So far the cursor is only playing up for a few minutes when the puter is cold when it is started.Maybe it wont get worse.
