Static causing short to motherboard

post #1 of 47
Thread Starter 
Hey guys need an opinion. So I was gaming and I decided to charge my phone. So started to plug in the usb cable to the front panel and the screen goes blank. So i started experimenting with causes. I found that if i built up a static charge on myself and then tried to plug in anything it shut down the system. However, if I touched the case and plugged in cables everything is fine. So for my question. Is this just a natural thing that happens? Or is my electrical socket not grounded? A follow up question to the latter option, Do you recieve an electric shock from a grounded source? cuz I would get a small shock after building up a charge and touching my case. So that leads me to wonder if its my wall socket and not my motherboard because this has happened on two seperate cases and mobos. Any info would help.

Thanks

To me it sounds like your rig is not properly grounded.. I would first try moving your rig to a different socket, and if it doesn't change it it's definitely grounding issues.

Got a multimeter?

Before you move your PC check the sockets in your house

If it was built pre 1960's then there is a chance that your house isnt grounded.

No I don't believe I have one. The house is from about 1990 but where I am is an addition to the house built around 2003 i think. Should be grounded but maybe somethings wrong with this particular socket ill try moving it

Unless you've done something like used an extension cord the doesn't have ground or have your PSU separate from the case it's probably already grounded, and you just got a shock from static.

As far as the phone problem goes.. I'm still trying to think.

Oh I was just using the phone as an example. It happens on other devices too if i don't ground myself before plugging it in. The PSU is installed in the case correctly and plugged into an extension cord that has a ground wire. So idk.

The ground like was on? As in on that the ground was working or on as in warning this isnt grounded?

If it is grounded i would suggest you open up your case and make sure there is no contact. Static shouldn't affect USB

Well, let me go through a few small things I can think of.

Make sure the motherboard IO plate is inserted securely. Make sure it's not loose if you push on it.

Check inside your case for potential metal contacts.

Also, if this just recently started happening.

1. Shake the case, does it freeze? If it does the motherboard or wiring is grounding out.

2. Any new hardware installed recently/any hardware changes?

3. Any damage? Check all components and make sure they're inserted properly, especially PCI-e and memory.

4. Anything spilled?
