comcast norton 360 Blue screens my machine

Hi,

 

I have a new  pc that I builtI have been building my own pc's for 20 years - I know the pc is solid  

asus p6x58 mb

i7 820

6gb ram

2 5770 video cards crossfired

7 professional 64 bit

 

 

All is working fine with mcaffee. Comcast is switching so I figured I would follow their install. The 360 installed but with in a day I started getting blue screens.

 

OS Version: 6.1.7600.2.0.0.256.48

Locale ID: 1033

Additional information about the problem:

BCCode: 7f

BCP1: 0000000000000008

BCP2: 0000000080050033

BCP3: 00000000000006F8

BCP4: FFFFF80002E6C40F

OS Version: 6_1_7600

Service Pack: 0_0

Product: 256_1

 

So I uninstalled , ran norton removal tool , ran mcafee removal tool , then reinstalled 360 - same thing.

 

Uninstalled everything again and ran removals. Installed mcaffee again. Have not had a blue screen since.

 

Any ideas? I know that my sub. to mcafee will run out and 360 is free from comcast

 

I am thinking maybe it's the crossfire - but not sure.

 

Thanks
