Debugging Dumps and other issues - help?

Everytime my pc*shutsdown, it blue screens after about 7 minutes.
It says "Shutting Down" for about 7 minutes and then dies.

When I restart, I get a message saying that Windows wasn't properly shutdown.

I used the Dump Debugger thing that was mentioned in the NVidea thread, but it isn't so helpful. The message is:

<b>Probably caused by : ntkrnlpa.exe ( nt+d8681 )


</b>So my kernal is bad?

This is a brand new (just installed < 12 hours) installation on a brand new PC.

Another wierd thing is that when I try to intsall the intel ACHP drivers, it says my machine doesn't meet the minimum requirements, but I know it does as its a G33 Express board with a Q6600 chip and daul SATA HDD's.
