what's your soundcard, os, cpu & memory on that comp?

all I can think of is the usual stuff, run an anti-spyware prog like spybot or there's one for free from avg these days (could be some app eating your cpu), run a free prog called ccleaner (google it) & check if there's anything in the autoruns that shouldn't be there, clear as much space as you can & defrag.

then try the transfer, do it right after a fresh restart with the screensaver disabled & pull your connection to the internet right out (ethernet or otherwise). Hopefully this will help!
