Electrical Problem

[Moose93]

so, i built my first PC a couple of weeks ago and i have hit a slight snag.... i can feel a tingle of electricity through a thumb screw on the case. i only noticed this when i touched the screw while plugging in the HDMI, i cant figure out what would be causing this (its only when i have power going to the computer so i presume it is electrical). 

 

i havent turned on the PC since i noticed this as i dont want to fry anything, thought it would have done that anyway though. the ONLY thing i can think that is causing this is the graphics card touching the PSU, i used the stand-offs needed for the MOBO so its not that, someone has said to put rubber grommets on the stand-offs but they werent even mentioned when installing the MOBO in the guide i followed (the phenom M build on linus tech tips). 

 

if you have any idea what could be causing this, please let me know. i dont want to have a £1000 PC that i cant use

first thing, check the motherboard standoffs aren't touching anything. they, and the PSU, and a few usb plugs should be the only things that might have power with the system switched off

Make sure your mobo is on the standoffs like it should be (not touching the case) and that the I/O shield and tabs are in place correctly.

Could be a screw somewhere under the motherboard making contact. Could be a riser in the wrong spot. I have also had a peculiar encounter with a faulty power bar that caused the same problem and an improperly wired electrical outlet will do it too.

 

The strangest one I think I've ever had was a motherboard tray that was curved, took me forever to figure that one out, the tray was bowed in the middle so it made contact with the bottom of the motherboard.

if none of the above works, lets return the psu and get another brand, what su did you get?

turns out it was just a loose screw in the case, took it out and the tingle went. thanks for the help though
