PC Case Gives Weird Shocks help

[001rasmus]

So this started happening last week and basically what happens is that when i have been playing games for a while and if i touch the side of my pc case, it gives me this weird shock. Its not like a *snap* shock its more continuous. All groundings in my psu and outlet are fine and i dusted the case.

Does anyone know what might be causing this?

Also i can hear little crunches from the case sometimes if thats any help.

it might be caused by heat differences?

Ground yourself against something else that's metal before touching it next time. See if it makes a difference. If it doesn't, you're probably fooling yourself.

You're grounding out to your case somewhere, find the ground, it could be in the power supply that a wire is touching the bottom at the solder point or within one of the wires having a small hairline slice in it.

I would throw out the PSU immediately. You have 110 ac coming in and 12 volts dc and less leaving the PSU. I have never been able to feel 12 v dc so that leaves 110 ac which you can feel.

Check your ground.
