Cannot run windows in safe mode
I am trying to restart my computer in safe mode ( i have windows xp) so that i can wipe the nasty AntiVermins off of it. But i cannot do it. When i try restart, no matter how many times i hit F8 it does not go to a different menu, and there is no magical Beep before the windows sign comes up, that i'm supposed to wait for before hitting F8 either. Also I cannot seem to get to the part where i can choose a different user to log into the computer. Sorry for the ramble but can anyone help?
