[Neth12]

My pc has worked fine past few year's but since yesterday it gives lots of electrical shock...when i put my Arduino board or usb it shocks me and turn of breaker .
And also audio out connected to subwoofer that wire also shocks me..Why..

What is full system spec including PSU make and model?

The might be a short or the PSU might be failing. I wouldn't turn the PC on with that PSU unless you have it tested and it's OK.

I would check the case grounding.
There are many ways to do this.
The best way is with a multimeter.
Put one probe on the case and the other on a KNOWN GROUND and you should see very little resistance. If you don't....there is a problem with the outlet, the power cord, or the PSU.
