Grounding the Mobo

mjoliat said:
When I built my system and installed the CPU cooler, there was a backplate for that cooler. The instructions said to peel the heavy paper off of the backing plate. So I did. When I turned the system on, I had no display. I thought the Mobo wasn't working. I starting doing a little poking around and going through the building process and decided that the back plate was probably shorting out the board. I put that backing paper back on the backplate, fired it up and everything was good. You might want to think about if you have a situation like that.

That's a weird situation because normally you are supposed to take the paper off. :(
 
We use to do all our testing work with a power supply that had been removed from the computer case. The mother board was laying on the counter top with the power supply, monitor, key board and mouse. Plug the power supply into the mother board there is a ground wire on the power supply plug that provides a ground for the mother board so screw ground is not required. Some times those silver places that are intended to be a screw ground will short out the mother board that is why I never use screw grounds anymore. I use plastic screws on the mother board.
 
All the case-grounding stuff is about emi shielding.

If the darn thing work/doesn't work when grounding the board, the error is usually somethine else.
