start up hangs

I've tried to installe Vista B2 several times now. But I haven't been succesfull.
This is mij system: AMD 3300+ 64 bits 1GB memory 128 MB nvdia VGA 2 HD's IDE, 35GB and 80 GB, 35 GB is my desired instalationdisk DVD-player (IDE) DVD-burner (IDE)
The problems always occurs at start-up of vista (before even installing). (couldn't find or make a screenshot, but it's the Vista equivalant of the following XP-screenshot: http://www.themexp.org/screenshots/large/boot/11127.jpg ) I tried the following things: 1: install when booting from DVD with the 32 bits version. 2: install as dual boot from windows XP (it installs untill the computer is re-booted during setup) again with the 32 bits version. 3: install when booting from DVD with the 64 bits version (yes I downloaded that one as well, you could never now) 4: because off step 2 I could use advanced start-up options, so I started with the logging function on. no log was created (I asume because windows hasn't stated far enough). 5: Running the upgrade advisor. Besides the fact that bacause of step 2 there wasn't enough space on my hard drive (rubbish fom that instalation), It said that my system was suitable and ready for Vista.
Off course I am aware this is a Beta, but I upgraded my PC very recently to be ready for windows Vista. So hopefully someone can give me a sollution (or keep my fingers crossed to see if this problem is solved in the final version)
