Outlook 2000 reminders

I need to know if keeping the Outlook reminders up, slows down (or uses resources) on a pc? What I have is a user (manager) that has about 50+ reminders start up everytime he starts up his outlook 2000, then he complains that his pc is slow (he has a Dell 800mhz w/128mb ram W2k os). I tell him it’s his reminders but he want proof.
