MB damaged by video card?

Hi there folks. I have recently gotten my BFG 6800OC AGP card back from RMA (it had a horrible stuttering issue) and it ran great for 5 minutes until my computer suddenly just shut off with no warning. When I hit the power button to turn the computer back on, a small ploom of black smoke came off the back of the 6800OC and the chip where the smoke came from was glowing orange!. I instantly pulled the power from the power supply and took the card back out and slapped my 9800pro back in. I've now RMA'ed the newly defunct 6800OC card, uninstalled the Nvidia display drivers, used DriverCleaner Pro to clean out any of the Nvidia display driver tid-bits and re-installed the ATi Catalyst 5.7 drivers. The problem I'm having now is that my computer for some reason reboots for no apparent reason ever since the 6800OC video card went "poof"!
My systems is as follows:
AMD Athlon64 3500 (Clawhamer core)
MSI K8N Neo2 Platinum
1-Gig Patriot PC3200 ram (2-3-2-5 timmings)
ATi 9800pro 128MB
SB Audigy2 ZS
Antec Truepower 430
WinXP pro SP.2
When just browsing the web and doing e-mails the system usually reboots itself in about an hour. When gamming, the system reboots itself in about 10 minutes. Could the problem with the video card cause damage to my motherboard or PSU? I would greatly appreciate any assistance with my problem. Thank you.
 
Any chance the PSU got overloaded? How old is it? Is it the TPII with dual +12v rails?
That 6800 draws more +12v power than your old card so perhaps it is possible the PSU got
overloaded and passed a spike along to the rest of the system.
Though Antec surely have good overvoltage/overcurrent protection - just a thought.
 
well there's always possibility that the agp slot got broken a little... you can easily rule that out if you can get a hold of a PCI vid card...
 
BUMP.....
....because I still need help with this. Its really quite aggrevating to only play BF2 for only a few minutes before my system starts rebooting again. I have e-mailed BFG about this and asked them if the fried BFG 6800OC could have done any damage to the motherboard or power supply, but I have yet to get a responce from them.
 
You haven't raised your AGP voltage or something have you? Some people think it will get them a better overclock (but it doesn't.)

Only other thing actually motherboard related I can think of is AGP bus. Setting it higher than the 66MHz it should be locked at shouldn't actually damage a card or board though, just cause instability. If AGP voltage is normal, I'm definitely inclined to blame that PSU. Let's not forget, the 6800 DOES use a molex connector for that extra power. It could be the power regulators were having problems or something. If they screwed up and the card was running too high or something, it might maybe manage to damage the AGP part of the MB. Mind you, my dad, one of his friends, and myself all use ThermalTake PurePower PSUs and none of us has had a problem in the world, but, it's always possible that there can be a single bad one in any product (though I've never heard of anyone with a problem that bad.)

And Susquehannock, that PSU is definitely not old. I don't know what specific rails it has internally, but, I can definitely say that my system reports it as having a + and - 12V if that's what you mean. (They are both showing different voltages, so are either read at different times far enough apart to have changed or are two different things.) If you mean the extra 4-pin plug for the 12V cpu, it definitely has that (required in my case, my system won't boot without it.) In any case, 420W never has caused anything like that in my system, so it's hard to believe 430 is a problem in his unless he has a Raptor RAID array he forgot to mention.

Uhm, I say find some PCI card and see if your system is still stable. If the video card actually messed up like that and damaged part of the MB, it MIGHT have been related to the northbridge or something. That would mess up more than just the AGP and you'd definitely see instability.

EDIT: Oops, misread TruePower as PurePower somehow. d-:
 
Try turning off Fast Writes or adjusting the card to run at 4X.
 
Well over voltage and overclocking are not my thing, plus I don't muck around with the bios much at all except to disable onboard stuff like sound and firewire since I don't use those anyways. The power supply is only a few months old and I have had no problems whatsoever with it. I have an old ATi RagePro PCI card I'll try out later today to see if I'll have any instability problems with a PCI port. I'll try turning off fastwrites and seeing if 4X AGP speed will help anything as well. Since this is directly related to the blow-out of the BFG 6800OC card, do you think that they might replace the motherboard or power supply? Thank you folks.

You'd think wouldn't you?


Though my last Antec Trueblue 480w crippled itself after my 9800pro died in a similar fashion to the original poster (though less dramatic).

In my case, a capacitor inside the Antec PSU had swelled and clearly 'blown'. I probably could have just replaced it and repaired the PSU. Anyway, the result was that it was then just incapable of properly powering my pc. It just gave out low amperage meaning I could run the PC fine at really low speeds, but try to push things and it'd flake out causing crashes/BSOD's etc.


So yeah, try a different power supply.
