Can the northbridge be damaged?

[whoololon]

As the laptop I've been using until now (an Aspire 7720G 5AG32Mi) has had its graphics card (a 9800m gt) fried, I've gone back to tinkering with the remains of my desktop.
I've put it back together and, when looking and re-looking at the Radeon 9800 TD128, I saw that one of the tracks on the AGP connector was cracked, twisted and broken like an old fuse.
The question is, could it have taken out the northbridge of the motherboard?
Without memory, the board gives me the corresponding error, and it also does so when booting without VGA, so that's the only thing I have to intuit that the board is fine and that it won't fry everything that plugs into the AGP... because I'm nowhere near ready to buy another system.
The message in question.

What do you think?

Thanks in advance.

I would say that a chipset does not have the "strength" to power a graphics card. The twisted track, I suppose, will be one responsible for transporting power. Anyway, it seems very strange to me. I would be more suspicious of the power supply than the chipset.

Don't you have a broken card around to test?

That's the issue, I'm considering buying another card (the last new one for AGP) and I wouldn't like to install it and have the same problem.
On the other hand, what I published back in the day was the "light" version, the issue was that it literally exploded, even a metal pin that held a backplate to dissipate the heat of the memory modules flew off.
As always it suffered from overheating (the heatsink group that came with that MSI was a disgrace for what it cost me), and it was always above 70º, so I thought it simply burned out. That could have been from the FA, that by the time it happened it was barely a year old, I just didn't think about it until I saw the clue (and you pointed it out). I have nothing to test, this is a silicon morgue.

The original computer, assembled in 2004, was an AMD K-8 at 2.8Ghz on a GA-K8NS, 2 GB RAM and that MSI RX9800-TD128. Initially it had a TT Purepower 500W modular power supply, which died and was replaced by a NOX URANUS AT-600P12P, not modular.
If it turns out, as it seems to be, that I also have to change the power supply… maybe it would be cheaper to send the laptop for repair.

Edit: Looking at the card from the back, the burned track connects the last top pin with the group of resistors R1 and R2, which apparently are fine. I redid the track, but it's dead, no video signal or screen notice that the power supply is not connected. My doubt was if that incident could have damaged the motherboard, in which case I would have to throw the computer away.

The chipset doesn't have a built-in VGA? It's an nForce. They should be tough with the temperatures of the chipset itself. Anyway, take a close look at the AGP socket in case the pins it contains are also damaged. If you can upload a photo of the damaged part of the card and the motherboard...
