I was going to install Win 7 today, but it refuses to behave

I set my pc to boot from the disc, and just as it says 'Starting Windows' i get BSOD, every time. Any ideas what could be causing this?
Is the BSOD perhaps a bit more specific or is it just giving you the finger?
Does it happen while preparing the install environment or during the first boot?
It appears Win7 creates a seperate partition which it uses to store the temp files. Enough space? Empty disk?
Meanwhile:
- Try setting your BIOS to default values. Helped me during my install.
- Consider to install from an USB stick instead of disk (if your BIOS supports it) to circumvent problems with the drives. Also will speed up the install.
Also: Any new components?
