I've been having problems with my DSL disconnecting for no apparent reasons. It never did this before I moved (about 6 weeks ago)

Called ATT they reset my password blah blah still probs. I thought I had a virus or something (i'm not very computer savvy obviously)
Today I downloaded AVG 8.0 and spybot did a disk cleanup and defrag. Now I can not connect at all. Spent an hour on the phone with my DSL provider.
I can get online in safe mode so she says it's not their issue. A few minutes ago the red light came on my modem again even in safe mode. When I try to open explorer in regular mode it says it is trying to connect but never can or it freezes completely.

Any ideas what I should do?

I need help I have a midtern I have to take online by tomorrow night.
