I tried installing Vista Ultimate RTM build (both 32 and 64 bit versions) today on my new build. I've had XP running just fine for the past week (Memtest and Orthos both no problems). However, Vista installation always crashes at random places no matter what I do. Has anyone else experienced this?

This is my setup:
Abit AB9 QuadGT (latest Beta BIOS)
QX6700 @ Stock, cooled with Zalman 9700 LED
2x1GB OCZ PC2-6400 @ SPD
PNY 8800 GTS
Seagate 7200.9 300GB
Samsung SH-S183L SATA DVD-RW
Thermaltake Toughpower 700W
