First find an external monitor to test if its the screen on your laptop or the graphics chip in your laptop. If you have an external monitor then hook it up to your laptop and toggle the video over to see if you still see the spot.If it only shows on the laptop screen the Replace the screen.

Are you certain the laptop is not booting? I had one the other day, customer thought it wasnt booting, but it was the LCD screen that was bad. She had only a gray screen too. Something to try, with the screen up, put your hand on the top of the LCD (fingers on the plastics on the back side, thumb on the screen at about the same position) about 4-5 inches from the left edge and squeeze gently. Does the screen change at all, vertical or horizontal color lines? If it really is NOT booting, try F12 when first powering up and if you get to the boot menu, choose diagnostics, run them and see if you get any errors.
Try plugging in a standard mouse and changing the settings to it, Then re-boot. Once booted try plugging the TrackMan Wheel back in and changing the mouse settings back to it and re-boot again. Let me know what that does for ya.
I would suggest booting into Safe Mode with networking (do this by pressing F8 during boot. Just tap it every few seconds until you get the OS selection menu). Once you enter Safe Mode, go to www.gmer.net and download their removal tool. You may have what's called a Rootkit trojan. Those can stay in your system's memory even after a factory default reset.
