1. Dont use VIsta.
2. If you really really really want to use vista, and you have installed xp and 7 in the exact same conditions with the exact same hardware then your problem would appear to lay in the Vista installation disk.
will try installing vista on my own D945GCLF2
will reply to this thread!
ive sorted it now, updated bios and now it installs ok, tho ive decided to use xp pro for my car pc now, atleast till i can find an fm tunner that works with win 7.
