The case of the jumping cursor
I have a Dell M1530 laptop running Vista SP2. All of the sudden, I turned the computer on, and the cursor has a mind of its own. As soon as Windows boots, before I can even enter my password to login to the computer, the cursor starts jumping around. I have tried using the Dell touchpad driver, and a Synaptic driver, and neither changes anything. I currently have a wireless USB mouse attached, and whether the mouse is on or off, the cursor still jumps about. I used 'Uninstall Programs' to remove both touchpad drivers. Any suggestions as to what to try next?
PS: Sorry if this is in the wrong forum... I didn't know if this should be in hardware or Vista :-)
