so i built a computer with a msi k8n neo4 platinum. until recently i did not bother installing the acitve armor and fire wall (one of the reasons i bought this mobo) but every time i try to install it it crashes and gives me 0x0000007e . i have to use the windows install cd to go into recovery propmt and copyeid pci.sys to c:\windows\system32\drivers. this works but i tried to install 6.66 driver from nvidia and when i tried to install it it crashed again when it reached the network part. clearly the nividia 4 ultra is conflicting with the system because it runs on a pci channel, any ideas how to stop this, and does the fire wall and active armor need the software to work?
