Yesterday I came home happy from PB tech after buying a copy of win 7 home premium 64 bit, I bought it so that it might fix my computer having the same problem as listed above. It hasn't helped and has made my speakers generate an annoying buzzing tone non-stop unless I turn them off. The blue screen told me before restarting the pc that it was a ram problem, out of memory error. That is why I bought the upgrade from 32 - 64 bit Win 7 now its saying there is a problem with the display driver, catalyst 13.12 (latest) but also showed this on 13.11 (older) is there any way for me to fix this without spending any money on new parts... (I'm broke after buying win 7 ) ?
