I just bought my new computer. An HP Pavillion a1777c. Vista Premium OS, 2 GB Intel Core 2 Duo E4300 Processor. Running on a 60 day free trial of Norton Secuity Suite. It has an HP wireless Optical mouse and keyboard. My keyboard still functions properly, but the mouse stopped working and the pointer froze AFTER my 15 month old pushed buttons on the keyboard and mouse. I've tried reinstalling the driver, no luck, recnnecting the USB, no luck, trying to reestablish a connection w/receiver, no luck, changing the batteries, no luck, doing an on-line live chat w/an HP rep, no luck (all he had me do was reinstall the driver). I even tried to do a System Restore, no luck, and now I can't UNDO my restore point because of a system file error.
What could be wrong here, and how do I fix it???
