BSOD with NDIS.sys error

[alejandroAT]

hi all,

I used to have BSODs caused by modem drivers when connecting to the internet via USB.
I proceded to switch my modem to a COM connection and the problem was solved.

But after upgrading my connection and switcing from a usb dial-up modem (ISDN connection) to a speedtouch 585 (DSL connection) router, i started having BSODs with the error occuring on the NDIS.sys file.

After looking up the problem on the net i found that a lot of people seem to be attributing this problem to IRQ conflicts when one or more devices are sharing the same IRQ.

I looked it up and found that some of my devices do actually share IRQs. I list them below:

19: Creative X-Fi
19: NV GeForce 7800 GT
--------------------------
21: nVidia Network Bus Enumerator
21: nVidia nForce4 Serial ATA RAID
--------------------------
22: nVidia nForce4 Searial ATA
22: Standard Enhanced PCI to USB Host Controller

Now why would my soundcard and vga share the same IRQ?
Some people say that IRQ sharing is not a problem with modern devices. But i find others that support the contrary.
My sound card is slotted on the PCI furthest from the CPU (edge of the mb) whereas the VGA is PCI-Express and slotted on the PCIE closest to the CPU.

Anyone has any suggestions? thnx in advance.

Windows XP is pretty good about IRQ sharing. Most mobo manuals have a chart which shows which slots are share with which other slots. Example - here's my chart:

IRQ

I use this to determine which cards to put in which slots.

UPDATE: i managed to find more information on the subject.

It seems that my problem is a common one. This crash is generated by network components. Either Zone Alarm or my router freak out when Azureus is attempting to make one connections too many. Seems that there is a threshold for number of active connections that if exceeded makes the system BSOD. I have reduced the number of maximum global active connections that azureus can make from 134 to 80 and i m waiting to see if it happens again.

Anyone wants to confirm that the above is indeed a cause for BSODs?
