I am using Vista Home Premium on:
Athlon64 3000
MSI GeForce 7800GT
GA-K8NF-9 motherboard
2GB RAM

Every time I tried to install, the installer would BSOD near the end when it
tried to load my video drivers. The BSOD pointed to nvlddmkm.sys. I was
finally able to complete an install by letting this happen, then booting from
the disc and using the command prompt to delete nvlddmkm.sys. When the
installer tried to continue, it couldn't find the driver so it just went on
without it.

Any time I try to install video drivers, I get the same BSOD pointing to
nvlddmkm.sys. I have tried all kinds of drivers from the default one privided
with Vista, to nVidia's WHQL drivers, to nVidia's beta drivers. All give
exactly the same fault.

I have updated my BIOS, loaded default BIOS settings, and updated my nForce
motherboard drivers to no avail.

My system has never had any problems running Windows XP and it continues to
work fine when I boot it up since I installed Vista.

Does anyone know what's causing this and if there's a fix? I understand that
nVidia are having lots of driver problems but it seems that most people can
at least get in to Windows. I haven't been able to try out Aero yet!
