Hi, I don't know if this isn't too new for Vogons, but I've seen some 775 topics on here so I guess it's fine.

I just recieved an ECS nForce3-A motherboard (socket 754). Unfortunately, no USB peripheral (doesn't matter what kind) works.
It seems as if some stuff does get power (a USB drive I connected felt quite warm after some time), but nothing is actually recognized, neither by BIOS nor by the operating system itself (Windows 8.1 currently as I had a hard drive with it on hand). A USB keyboard doesn't even light up.
Connecting any front headers doesn't change anything and they show identical behaviour.
I've tried many BIOS settings, limiting USB mode to v1.1, disabling any KB/Mouse support, setting jumpers related to USB but nothing changed.

I could live with it and use a PS/2 keyboard and mouse but I need USB to boot.
What is possibly wrong? Will a PCI USB card let me boot from a USB stick?

Are the USB Controllers showing up in device manager?

I think they're showing up fine. There's three USB root hubs, two of them say 4 ports and full speed in Properties, and one of them says 8 ports and high speed. None of them show any devices to be plugged in or recieving any power. I also noticed my PS/2 mouse doesn't work, it shows up in Device Manager but says Error 10 - device has a problem starting.

I'm sorry for the screenshots, they're in Polish. If I should translate something let me know.

That's very strange, could possibly be a hardware issue like a leaky capacitor or something?

Now that I examined a picture of the motherboard I took when I got it, there's a little bulging cap right next to the RAM slots.
I wonder if that could be the case, and perhaps re-capping the board could help.

Unless someone else has some other ideas then, yeah recap the board and hopefully that helps.
