If your motherboard has an ICH5 Southbridge, you've just had a latchup failure. If it fails real bad, it looks like the picture he http://www.abxzone.com/forums/showth...light=usb+port The only official recognition of the problem is he http://tw.giga-byte.com/Motherboard/...AQ/FAQ_456.htm I think there is more to the problem, than that article explains. In any case, you'll need to use your warranty to get it fixed. For some people, the chip doesn't burn that bad. Like yourself, all USB ports stop working, and there is no visible sign on the top of the chip. In more severe cases, the computer will no longer boot and the chip ends up with that burn mark (always in the same place). This is symptomatic of latchup, where a conducting path forms between VCC and GND on the chip. I expect Intel knows what is going on, but I haven't seen any announcements from them. And so far, I haven't seen any postings of this problem happening with ICH6 or ICH7. And if your motherboard doesn't have an ICH5 on it -- what kind of motherboard is it ? Paul |

I got the system back the way it was before, nothing works.
But there is some connectivity on the USB ports.. there is light on the mouse (but it does not work) and if I plug a USB key, there is a red light on it (but I cannot access it)..usually the light is green. |
