when you're typing into the address bar and it "freezes", does it ever unfreeze when you wait a while?
my guess it that you could have spyware/adware or a CWS (cool web search) hijacker.

as for the floppy... possible virus? do you have any antivirus? run a scan, make sure you've got the most up-to-date definitions or try an online scanner like

if it isn't a virus, you may just need a new drive. floppy drives are less than $20. so it's an easy replacement.
