Static electricity discharged on ports freezes computer

Okay, so I built my gaming computer a couple months ago. At first, I had the Cooler Master 690 II case. Really liked the case. Roomy, good cable management, drive bays that you just snap components into (as opposed to using screws). It was pretty nice.

But I started running into problems. It seemed that whenever I touched the front panel ports or tried to plug something into them, my computer would either freeze or go to a black screen. It wouldn't turn off; it would just go to a black screen, and the monitor would go into its idle state. This would also sometimes happen even if I went up and down the stairs and then simply walked near the computer. Touching the metal front panel of the computer also resulted in this problem.

I wasn't really sure what was going on, but I was sure it had something to do with static electricity. I decided to experiment with what would cause this problem to happen. I did deduce that touching the metal front of the case or any of the ports (including ones on the motherboard) would cause the problem. I then removed the front panel and touched the metal chassis of the case. Even with large amounts of static electricity built up, nothing happened when I did this. The screen didn't even freeze. I found this very odd.

Thinking it was just a problem with the case (I had read several reviews about this happening to people with the same case), I returned the 690 II and bought an Antec 900 SE and put all of my components in it. The fact that it's a very high-rated case and the large fan on the top enticed me to get it. I later learned that the cable management sucks. And I don't like how you have to screw all of your 5.25" drives in. But, oh well.

Now I figured my problem was solved. However, once again, my computer would freeze or blackscreen on me if I even touched the front panel ports or motherboard ports. I've been dealing with this for quite a while now, and I think I'm out of time to return the case. I can touch the metal parts of cables on the side of the case before plugging them in to discharge any static electricity in them, and 95% of the time my computer doesn't experience any problems once I plug the cables in. However, this is annoying for me, and it shouldn't be happening anyways, which really bothers me.

tl;dr: I think there may be something wrong with my motherboard. I've had two cases do the same thing to me: If I plug something into the front panel ports or the motherboard ports, without first touching the cable to the side of the case, my computer either freezes or turns to a blank, black screen. I suspect static electricity is the culprit, but I really have no idea why this is happening. All of my friends can touch their gaming rigs or plug stuff into them without any problems.

Again, I think there may be something wrong with my motherboard. Or maybe there is some grounding issue that I'm overlooking. I'm not sure what the think anymore, though.

Any ideas and/or input are greatly appreciated. Thanks.

What motherboard are you using? I had a very similar problem on my Asus P8P67 Deluxe. Whenever I touched my top-of-case USB ports the computer would just shut off. I simply unplugged the connectors from my board and the problem went away. I didn't really look into it much, though, as I decided I could live without them. Not sure what caused it... could be some kind of grounding issue, but it'd be interesting to see if you have a similar mobo.
 
I have an ASUS M4A87TD EVO motherboard. And I'd rather not unplug the front port connectors from the motherboard, as I use the front ports regularly (headphones and USB ports).
 
Did you use the motherboard risers when you installed it into the cases?

Lol, I sure hope so.

I agree, it sounds to me like its the motherboard also, and definitely a grounding issue.

One thing you might could try is to pull the motherboard and use some plastic washer between the board and the risers.

I had this same problem with an ABit board one time, I did what I suggested and still no joy, they only way it would work if it was out of the box on a bench.

Come to find out something was shorting the rear panel and when it was up against the case it shorted out. I solved it, by removing the rear panel and it worked. You might also want to try unplugging your dvd drive and other peripherals first one at a time and see if that changes things.
 
Yes, I did use the risers when I installed the motherboard.

As much as I hate taking my entire rig apart, I will experiment with what you suggested, crackdaddy, and report back as soon as possible. Thanks.
 
Yea, pulling a mobo is no joy for sure.
try to line up some thin washers first though.

I might actually have some that would work great, they were plastic thin washers used to put together a tool shed, they gave me like 300 too many.

If you want them, you can get them, just send me a SASE to me and I'll send em if you can't find anything suitable local.

Hi,

I have exactly same problem with this mobo. This was with Win 7 since 2011 and still 2017 with Win 10.
Did you get it corrected?
Still same problem?
