XP svchost or something isn't working. This is desperate.

I decided to restart my computer, and when I did it brought me up to a password entery screen for my owner account. Since I never assigned a password I coulden't enter one and it woulden't let me in. And each time I got it wrong it said something about problems with my server host or something.
Since I coulden't get past that I decided to chose the option to restart, and now whenever I start it up an error message saying that "svchost coulden't write to (some stupid name)" and a short time later another message comes up saying "svchost coulden't read from (some completely different name)" and it takes a long time to start.
Now whenever I sign online it says I am online, but I cannot recieve info from any websites. Everything says "page cannot be displayed" like I wasn't online at all, when in fact I am. What the fuck is going on?

I am having to be on my parent's computer to write this since I can't do anything on mine right now.
