Installing A Mb

I'm installing a mother board there are 4 brass raised pins to hold the MB with, also some steel ones, will the steel ones short out the MB board??

No, they are fine. The brass stanoffs are preferable, but plastic or steel ones are ok as well.

To be honest, I would rather use more then 4 brass raised pins to hold the MB! 4 is very low, certainly when you install some PCI cards, attach a couple of flatcables and use a big cooler.

As mentioned, the metal pins [aka:standoffs] isolate the mobo from physically making contact with the metal case.

And though the four pins will stabilize the mobo and keep it front shifting positions, I would recommend additional plastic supports be used to also prevent flexing while connecting, agp, pci, pci-x add on cards or when connecting ribbon or sata cables.

Heatsinks are spring loaded when connecting to the cpu and sometimes additional support is needed as well.

Hopefully the mobo manufacture has included additional plastic standoffs to provide the additional support as needed. Additional standoffs can also be obtained from your local PC repair shop or online.

Good luck. Smile

Don't start buying standoffs from your local PC store or online. When you ordered the computer, the store must have received the case, which almost always contains a bag with screws and standoffs. Most of the time, the amount of those are far from what you will ever need. I have a complete box with screws, standoffs, jumpers, isolation pads, etc. over here. Go to your local PC store and just ask for some, free of charge!

Hello,

Modern motherboards are typically mounted to the chassis on metal spacers (standoffs). This ensures the motherboard is grounded properly inside the case, which helps prevent grounding loops and signals interference problems on the motherboard and the devices plugged into it.

I don't think it matters if you mix the brass and steel ones--they should both conduct electricity--but you might want to go with one particular type in case they are of slightly differing lengths. Screwimg a motherboard down to different length standoffs can cause the board to flex, loosening the mechanical connections between parts and possibly even the traces on the board.

Would you believe that I purchased an Asus board from a "popular" vendor, and it had a bad agp slot, so in asking for my return authorization, they refused to give me one until I tried putting paper washers between the spacers and the mobo and between the screws and the mobo? I have no idea how it was to have been "properly grounded" if it had NO connection to the chassis......... and that was their top tech support guy.... needless to say after much complaining I got a new board that indeed worked like a charm!

Sometimes tech support people frustrate me! Surprised
