I didn't have a Theme either. It is weird since it works perfectly on my other laptop which is a Toshiba.
The one I want to install it on is a Clevo D740V with a 3Ghz Prescott. Does SP2 support hyperthreading? I just cannot find out what is wrong. I cannot reinstall my XP since I have too much stuff on it, like my development tools and everything. Is there a way to find out what could be wrong?
