Vista & Blue Screen of Death

My system is:

AMD Phenom 9600 X4 2.3GHz
2x 2GB Coarsir DDR2 667Mhz RAM
ASUS M3A
Vista HP x64
256MB Raedon 2400 Pro
20X LG Dual Layer Writer
500GB SATA HDD

I am using Vistax64 HP in order to run my 4GB RAM.

I have installed all hardware drivers and up to date windows updates including SP1.

I have tested the RAM and other hardware to check if they are faulty and i am possitive they are not.

Does anyone know of any additional support or patches/drivers or software i need to install

Thanks

you most likely need to post what kind of error you're getting in your BSOD before anyone can help
