Bizarre System Crash

[PCMarine]

Hey guys,

So I just got my Netgear Gigabit switch today (GS605), though when I plug my NIC into it my system just turns off - no software error, just a hard turn off.

I am using the onboard gigabit nic on a VNF4 Ultra motherboard. (Athlon 64 3800+, 1 gig ram, etc). The switch works fine when connected to other computers, so I'm led to believe my motherboard is the issue.

Anyone have any ideas?

Since no one else has replied I'll take a shot...

If I understand the events thus far, your system worked fine until you connect to your new switch, then shuts down but other computers on the switch work fine.

Have you used the on board NIC before with no problems?

Have you tried another CAT5 cables?

Have you tried just isolating the hardware by connecting the pieces one at a time, such as an open ended Ethernet cable to your PC, then connecting it to the switch, then DC power to the switch, then other PC's etc?

I've got the same switch on 4 computers with no problem. If your on board NIC is known to be good then I would look for either a short in the cable or possibly a voltage problem. Are all PC's on the same AC circuit? Any chance of reversed polarity on one of the outlets? Sometimes an AC outlet can be wired wrong causing a reverse in polarity. Once connected to another device properly polarized it can cause problems. I'm not suggesting this is it, and it probably isn't, but a hard shut down when connecting to other working devices would lead me to look for a ground or voltage problem.

Just a thought.
