Hi,

 

Recently tried installing a new wireless mouse on my dimension desk top but somehow in the process completely messed it up! 

 

So now after restarting the computer neither the standard dell mouse that came with the computer or the new one works!  I must have un-installed the dell one somehow in the process as now when the welcome screen comes up the mouse is completely frozen and i can't do anything!

 

So i need to know how to get things working again!  Any help would be very much appreciated!

 

Thanks!
