The Touch of DEATH (dramatic but somewhat accurate title)

post #1 of 6
Thread Starter 
Somewhat funny story:

I am a university student and I am constantly balancing my files between my laptop and desktop computer (dont trust cloud stuff I guess). My wife was on the laptop in the other room and I needed stuff off of it, so I walk over there with the jump drive, get the stuff, plop down at the desktop and plug the drive into the usb port in the front.

Black Screen.

The computer resets itself! No BSOD, nothing. Just a hard reset. Confused I boot up and continue working on my paper. I have to get another file from the laptop and the same thing happens when I come back. um... what?

After some sherlock holmes quality investigation I realize I am in a SUPER dry climate, my heater is on and it is cold outside. Dur... I am killing my PC with a static touch that apparently I cant feel.

TL;DR - Static shock from plugging USB drive into front of case causes hard reset.

What I know: I can plug the drive into the back (directly into the motherboard) even if I drag my socked feet around on the carpet for a while. It seems that my Mobo is grounded just fine. I think the static is just screwing with the reset button connection 2 inches from where I plug my usb drive in.

Any thought as to how to get rid of this problem without wearing a wristband everywhere? Thanks!

Ive heard of this with some of the older Cooler Master cases. The problem is that the front ports are mounted in a plastic housing that isn't grounded to the metal part of the case.
I'm not sure how your case is configured but it sure sounds like this is the problem. If so you can add a ground wire from the front port pcb to the metal case.
Cooler Master's now all have this added ground wire.

I just took a look at a pic of your case and I'll bet the front ports in the top bay aren't grounded.

That is exactly the problem. I ripped off the front case and it is all enclosed in plastic. Does anywhere on the case work for a ground?

During the winter time I have a very similar issue with my computer. If I plug headphones into the front panel, I need to touch the tip of the plug to the case or a metal bit of my desk before plugging it in. Otherwise, the computer just reboots itself.

Try to find the closest place in the case metal that already has a screw or a spot where you can add one. If the 5.25 bays are metal you could secure a wire to one of the optical drive holes.
