My internet explorer is messed up, see, what happens is that when theres anything running that takes up a moderate amount of ram (e.g. Kazaa, MSN, and so on) my internet explorer will just freeze and it'll say, error has occured and blah blah blah, everyone knows that message

, but anyways, Happydude666 recommended that I get the Windows Update, but now the problem is that you get the updates fromt he internet, using internet explorer, and right when i'm about to Download them the f**kin message shows up again, i've degfragmented my hardrive, i've used scan disk, i've deleted all the programs i don't need, and i've checked for viruses, I'M CONFUSED!!!!!
Can anyone help me??????
