Hi guys. Been playing with this problem for a while now, without actually dismantling anything significant in my case. I did check the wiring, all looked ok, I reseated the connectors on both ends. For a while it seemed like the problem wasn't happening any more and I thought I had it fixed.
But its back and its weird. For one thing it is not consistent. I will attempt to plug in a USB device and the system will restart. When the system comes back up I can usually plug and unplug USB devices to my hear's content without any problem ................. until I don't do it for a while.
The reason I am writing in this thread again now is because tonight I was going to plug a USB device into one of the front USB ports in my case. All I did was touch the USB plug to the USB port. By that I mean I had not even pushed it into the port yet. As soon as the metal from the USB plug touched the metal of the USB outlet, the system restarted. When it came back up I tried and tried to make it fail again and was not able to make it fail.
Could this have something to do with static discharge or something? Is that even a reasonable guess? If it's a short, then why after it restarts is it fine to plug stuff in and out a million times with no trouble. It seems its only after I haven't used the ports for some time that it happens and then only the first time I try to use it.
Here's another question that's probably stupid. The case is sitting on a shelf that has about 4" legs on it. Does the fact that the computer is not on the ground mean anything. I guess the question relates to my question above about whether this could have something to do with static discharge.
I don't know, I'm groping at straws. Definitely need help from smarter minds than mine.
Help please ................ this one is driving me a little nuts ...............
You have an Asus board, which means it comes with the Quick Connect blocks, that make it so you can insert the connectors wrong, so thats out of the question. Did you use standoffs on the motherboard tray when you installed it? If you didnt, it makes it very easy for the motherboard to short out if it contacts the motherboard tray.
Other than that, I would look for a damaged wire, something contacting the chassis itself, most likely behind the front panel.
Have you been able to duplicate this same problem using the rear USB headers on the motherboard?
