Bluescreen and boot up issues with Vista 32bit

When I start my pc up sometimes it gets to boot from disk then just shows a blackscreen, or just shows a black screen from when I turn it on, once I got loads of white lines across the screen and today when I tryed turning it on I got a blue screen saying something about windows having an error, the computer shut itself down too fast for me to read it. If I manage to get to boot windows it says "windows had to shut down" or something then gives me the option to boot in safe mode, if I chose start windows normallyi just get a black screen, if I chose safe mode it loads up fine. Then if I restart from safe mode windows boots up normally fine.

Yesterday the pc shut itself down while I was playing music too, it has only shut itself down from windows once while playing music. I've ran a memory check useing the vista disk and my RAM has no errors. Is it possible my motherboard or graphics card is broken? The last things I installed where GeForce PhysX drivers, fraps and PC Probe II.

My mobo is a P5Q Deluxe and my graphics card is a 512mb 8800GT.

When I started in safemode it gave me some info about what happened, here it is:

I've had this PC about 2 weeks (built it myself) and ive had no problems till now, so im rather confused has started happening. Ive been defragging the hard drive every week too and as I said earlier I have checked my RAM (4gb corsair TwinX).
I'll upload a minidump (had to zip it as it was 30kb over the boards limit), and I will be grateful for any light you can shed on my problems.

Just got another blue screen, this time while playing Flatout:UC with winamp playing music in the background.

I've attached the minidump.

The MiniDumps cite 2 different Drivers "aswMonFlt.sys" and "sptd.sys", the first is a Avast Anti-Virus Driver and the other a Daemon Tools Driver.

Quite a few have came up with this where Avast doesn't seem to like Daemon Tools, you need to choose to uninstall one of the Programs and use a Alternative.
