basically replaced my mobo/ram/cpu yesterday without formatting or anything like that. everything works fine except my internet seems a bit funny - haven't been able to send any emails (can recieve them) and bittorrent wont give me a green light (worked fine before). i'm using am origo 4 port router
not really sure what could have happened although i am using the onboard lan rather than my old standard ethernet card - could this be the cause of the problem?
Replacing the mobo w/o a reformat can cause lots of problems. I highly recommend doing a backup/reformat.
Did you have any ports forwarded to your computer for bt? bt needs ports just like any other sharing software.
Make sure all your email info is right (pop3 address, smtp address, etc).
