I recently built a new gaming pc. A few weeks ago, I touched the USB port on the front of a cast, exchanged static charge and the pc rebooted. Since then this has happened a few times. I want to fix this asap so that I dont fry my components. I know this is a grounding issue. I need help determining if this is an issue with the case (including case and usb ports) or if it is a mobo or PSU issue.
PC Build:
AMD FX8150 Eight Core 4.00GHz
Gigabyte 990FXA-UD5
HD Radeon 7970
16 GB Ram
Kingwin Mach 1 1000w PSU
Case: Thermaltake Overseer

Re: Static discharge to USB port restarts pc
Do you have the PSU earthed?
Looking at the case, it is a Thermaltake which immediately rings alarm bells in my ears for noise reasons but I am not familiar with this one. Is the case front plastic or metal? Is their metal to metal contact all of the way back to the PSU? The USB header has a built in GND pin so there should be no problem with that unless their is a lot of current going back through it, hence why there might be a problem with the fascia not being earthed.

Re: Static discharge to USB port restarts pc
Sry for the delayed reply. It turns out that the GND from the usb module was shorted. Thermaltake sent me a new usb module and no more static!
