Computer Freezes When Case Is touched
My case is a Corsair 800D and I have built computer for a very long time. I have never experienced this before and want to know how to address this issue. Tomorrow I am going to reseat the MB as my first step in trying to fix this issue. Look at my system specs to see the complete build.
Just lightly touching it anywhere? Does it freeze until you take your finger off? It is very odd, but would seem to point to some sort of grounding issue. It is of great concern, and you will want to figure it out as soon as possible!

Some times when I put one finger on it it locks up. Some times I can touch it up to three times (taping). If I put my hand on the case it locks up right away. I had another MB in this case and never had an issue with it so I know there is something wrong with some type of grounding with this MB that is the issue.
I agree, it may not be contacting the standoffs correctly. If the problem is repeatable, you might be able to confirm this by identifying a ground point on the MB, and connecting an alligator clip from it to the chassis. A Guy
Ok, just re seated the MB and still locks up. Which ground point should I use? The Rampage IV E has several ground points. I was thinking using the connectors that came with the MB for voltage measurements and connect that to the ground to the case. Would this solve this.
Also when I was re seating the MB I noticed that the shilding on the IO back plate was bare on the right side next to the audio out puts. The far most right ones only were shiled from half of the port width.
I'd think the ground for voltage measurements would be ideal. It will at least tell you if a general MB grounding is the issue. Since touching the metal case seems to cause a freeze, it would have to be hardware related somehow I'd think. Although there could be both cold ground, and hot ground parts of a MB (I am unsure if this applies to PC MBs). The ground testpoint for voltage measurements would have to be a cold ground. A Guy

On the upper right of the MB are the voltage and ground measurement points I was thinking about attaching the wire to the extra standoff to the right of that spot. What do you think?
Hard to say with those pictures :) But the chassis is ground. The MB grounds to the chassis through the standoffs usually. So as long as you are sure the MB test point is a ground, then any point on the case (chassis) would work. A Guy
So the ground on the MB does not have a pin out only a place for you to soder a wire onto. So until I find a better solution I attached a wire to the back side of the MB back plate and use one of the un-used treaded holes to mount the wire. Then I ran the wire to the out side of the case and use an extra power supply plug and put the wire into the ground and then pluged the cable into the wall. Now the case is grounded.
I need a better solution then this.
I take it touching the case does not freeze the PC now? Is the MB under warranty, because no way should you have to add any ground wires.
