system-start driver failed to load: i8042prt in windows vista.

Hi all of you, actually I installed the windows vista in my Pc. Actually I have problem with the vista business whenever I start my computer and then every time I see that computer manadgement/event viewer/administrative events it has an error massage: the following boot-start or system –start driver(s) failed to load: i8042prt. I was thinking that the problem may be in driver but I checked that everything was fine and my driver was up to date. Anyways there are also so many error and warning I am getting. It may be due to installation of the both XP and vista. One more thing I just wanted to say that I am not getting NO restore point after rebooting. So can anyone tell me how to solve this issue?
