BSOD - Anyone good with minidumps?

Hi. I'm new here, and I have a problem with my computer. BSOD.
Helluva way to introduce myself!

Basic and brief introduction of recent history and current problem:

I recently upgraded the following hardware:
Motherboard: MSI K8N Diamond
Video Card: XFX GeForce 7800 GTX (UDD7)

I eventually found out that my PSU was insufficient in more than one way. It had only 20 pins, and the motherboard had 24 pins. The PSU was only 360w.
I experienced that the PSU would shut itself down under heavy load..

So I upgraded again. New PSU:
Thermaltake Purepower 680w, 24 pins..

I also got a new CPU-cooler:
VapoChill Micro Ultra Low Noise

After installing the new PSU, the computer no longer shuts itself down. Since the power was sufficient. However, I sometimes get a BSOD.. but not immediately. These BSODs are very rare. One per day so far. They only occur after every basic software driver is installed.

Event Viewer logs:

More info:

As I observe the event viewer, every time the savedump happens.. I also see something happening under "Application" at almost the same timestamp:

2nd October:
System: EventID 1001 = Savedump 00:54:09
Application: EventID 1800 = SecurityCenter 00:54:19
Application: EventID 0 = ForceWare Intelligent Application Manager (IAM) 00:54:19

3rd October:
System: EventID 1001 = Savedump 20:29:21
Application: EventID 1800 = SecurityCenter 20:29:31
Application: EventID 0 = ForceWare Intelligent Application Manager (IAM) 20:29:30

It could just be me, but these seemed connected somehow.
I have uninstalled Nvidia Forceware Firewall.. I heard it was... problematic
So far so good, but it's too early to tell. I only get something like 1 BSOD per day anyway..

The culprit is nVidia Firewall. De-install nVidia Firewall and install other firewall.

BugCheck 19, {20, 8790d208, 8790d2a8, a140004}
Probably caused by : NVTcp.sys ( NVTcp+1d9f )

I did HOPE someone as astute as yourself would comment, but I didn't expect it. I'm honored to have your help. And you are a great person who helps people without asking for anything in return. The least we can give you is the recognition you deserve, as a great tech support expert, and a very nice guy. :)

Thanks so much. It just confirms my suspicions.. I already did uninstall it..
and so far soo good! :D
