I've got a strange problem that very occasionally (maybe once a month) when I plug something in to the front USB port on my computer, the computer suddenly restarts. This also happens sometimes when I touch the front USB ports. This has been going on for a few years and a lot of the components in my PC have changed.
- I thought it was my home wiring, but I moved last year and it still happens.
- I thought maybe it was the motherboard, but that was upgraded 9 months ago and it still happens.
- I thought it was my case, but I changed that recently and it still happens.
- I thought maybe it was my PSU, but I upgraded that yesterday and it still happens.
I'm pretty sure this is an electro-static thing, but I thought that modern computers have protection against this sort of thing. Maybe I should move my case off the floor (carpet) and stop wearing songs all the time.
Edit: Just to clarify, this is a computer that I built. The components have been upgraded throughout the years and it's not much the same computer anymore.
This doesn't happen very often, but it is annoying, because I don't know what the cause is. Anyone have any ideas?
Well, I built it so some of the components are under warranty. The cables are plugged in correctly and it's not the port, because this happened with two different computer cases. – Mark A. Nicolosi – 2010-02-08T00:36:22.053
next thing to check is the motherboard ground. Make sure the screws that connect the motherboard to the PC case are correctly installed. They should touch the small metal circle around the hole on the MB and connect it to the PC case. – Chris Nava – 2010-02-08T03:46:28.587
Two different motherboards and two different cases. All using the stand-offs and screws that came with it. I'm wondering if a wireless mouse dongle could be the cause (it's always plugged into the front)... – Mark A. Nicolosi – 2010-02-08T05:11:50.990
