I've never really payed attention to my brothers Windows 2000 till i went a stole 10 dollars from him(=P) and i decided to look on his computer....no anti virus or anti spyware and a **** load of downloads from my cousins who are computer illiterate... i cleaned off a bit of adware and downloaded him NOD32. I decided to do a Microsoft update because knowing him he hadnt in awhile....when the thing loaded it said "Your computers time and date are wrong....or something like that and i checked time AND dates and there right....i ahve know idea....is the computer done getting updates? like its too old?

Go into the BIOS and see if the time/date are correct there.

And give your brother back his money.
