Tilted Forum Project Discussion Community - View Single Post - Installed a PSU and video card, but now my ethernet doesn't work

So I got a couple of new toys for my birthday: a Corsair TX 650 and a Radeon HD 6850.

I got both of them to go in and got them up and running, but now my integrated ethernet seems to have gone dead.

I tried all the regular troubleshooting in Windows Vista.

I tried rebooting my modem and router.

I tried disconnecting and reconnecting the cables.

I double checked all the power connections from the PSU. (Two are connecting to my board.)

I checked Device Manager, but I can't seem to find the ethernet listed. As far as Windows is concerned, it can't seem to find it anymore. Under Windows Network Diagnostics, I get the error: "This computer does not have a network adapter installed and configured." When I go to Manage Network Connections, nothing shows up in the list; it's blank.

At the jack itself, the light no longer shines.

I don't know what else to do. I'm not very good at Windows backend stuff, so any walkthroughs or troubleshooting will be appreciated.

I suppose at this point I have two suspicions:

1) the installation of the new PSU somehow fried the ethernet adapter.

2) the power coming from the PSU to the ethernet isn't working.

There are two power cables connecting to the board. There is one on the far side that is a wide plug with various cables connecting to it, and another one near the back of the unit, close to the ethernet jack. This one is a smaller four-prong plug. I'm not sure what it's for, but I suspect it has something to do with the ethernet stuff. I could be wrong. Maybe it's for the processor. I don't know how motherboards typically work.

I chatted a bit with Martian about this, but I suppose now I want to open this up to more suggestions.

I think my worst-case scenario is dropping $15 on a PCI ethernet card to get the Internet going again.

Of course, I want to exhaust all my options first.

Thanks.
