Mobo and vidcard being fried by the network card?

[abrahaml]

My computer was running smoothly and all of a sudden everything shut down and wouldn't boot up again. After some basic trial and error, I determined that the mobo and video card were dead. I didn't test the network card or soundcard yet. I bought a new mobo and video card and everything ran fine with just the barebone setup (mobo, ram, cpu, video card, hdds.) I could boot into windows just fine. Then, I put in the network card and tried to boot the computer. After 5 seconds, the screen went black and now I'm back to square 1. I'll have to test everything one by one again, but I think the mobo and videocard may be fried again! Anyone have any advice?

Ouch The other part you have in common between the two is the power supply. NICs are cheap so you might want to throw it away on general principle.

i don't think your powersupply can supply enough electricity
that's why when you add an extra load(NIC) it shuts off.
just my .02 cents

I've seen PCI cards do something like this. I have (had) a SB PCI-128, that, when put into a PCI slot, the machine would post and then shut down. I took out the sound card and the comp started up fine. Put it back in, and it did the same thing, regardless of which PCI slot. I tossed the card, put in a new one and the machine ran fine. As, mech suggested, it may also be the power supply.

No...the computer won't boot any more, even with nothing in but video card, cpu, and ram, so it's not just a case of "plug in nic, can't boot, take out the nic, everything is ok." The same powersupply can run another complete system with mobo, vidcard, network card, raid 0, and 5 drives with no problem. It's a $100 enermax, I think. I'm pretty sure the nic must be bad, but I wanted to ask you guys' opinions. What actions do you think I could take if it really turns out that my nic fried 2 mobos and 2 video cards? This is pretty expensive stuff, one videocard was a geforce 3 ti200 and one was a radeon 9500. The motherboards were both medium to high grade abit boards.

my peer have an almost same condition. his mobo was fried out by vga card. he use a mobo with 1x support, while his card has only 2 or 4x. I think it was the different voltage.
In case of NIC's, they should be PCI's, and there are no voltage issue on it. Hardware incompatibility thing is impossible. Might be your NIC has closed circuit (production / delivery failure), so it causes high current and then eat your other component.
Suggest you took a hammer, and bam em out. Otherwise, complain this matter to the NIC ditributor.
I want to know what brand is your NIC.
