Frequent blue screens that quickly go away

[Kaonax]

so this has been going on for a while and I haven't really done anything to fix it until now. two things seem to have affected how often the BSOD's decide to interrupt whatever I was doing.

-installing new motherboard drivers
-replacing what I believe to be the north bridge chip fan (the fan was dead for at least a month without me noticing)

I think the north bridge chip might have gotten fried somewhat which lead to this issue, but I can't be sure

the BSOD's have gone away too quickly for me to read anything as well, although I've attached the latest 5 errors I've gotten from the minidump

let me know what other information you may need

Computer Specs:
AMD Athlon 64 3700+ 2.2 Ghz
Asus A8N-E nForce 4
1 GB kingston DDR PC3200 dual channel
Geforce 6600 GT
Windows XP Home SP2

help would be greatly appreciated!

The Nvidia Firewall is the problem. Uninstall it and replace it with one of the free ones. Comodo?

Wow, that was quick and simple. I was thinking it would be alot harder than that.
how can you be sure that's what it is?

It's still happening, here's 4 more minidump files

It's still installed. All the crashes are caused by NVTcp.sys. The Nvidia Firewall is a known problem causer.

Probably caused by : NVTcp.sys ( NVTcp+237f )
