Windows Vista Ultimate fails to install - Help

Firstly, my system consists of the following.
Asus P5WD2-E Premium
Intel P4 D 3.4Ghz
2Gb Dual Chan DDR2 - 6400
X1950 TXT PCI-E 512Mb
4 x Segate SATAII Barracuda 320Gb HDD
Sony DVD +/- RW / +/-R
Winfast DVT2000 H Tuner

Upgrade advisor stated I would have to unistall Nero and NIS2006 prior to
upgrade, also programs like power toys etc. I did this, and when to an
upgrade install. It started okay, the froze with a black screen very faintly
I could make out a progress bar and the word Micrsoft Windows or the like. I
tried again a number of times, same problem. Out of sheer frustration, I
decided to a clean install, formating my boot drive to recieve the new
operating system, and guess what, yes... failed to install, added the windows
files, the froze again.

Help anyone!
