Insulating with rubber

[Bidderdoo]

I just put together a computer, however, the motherboard kept shorting because it was touching the back of case somewhere. I cut a square piece of 1/8" rubber (10" x 10") and placed behind the motherboard, then poked holes through where screws went and screwed it down. It's working fine now, however I'm concerned the rubber may cause issues in the future. Is it okay to do this, or should i take it all out and make "rubber washers" instead with them just at the holes? Thanks in advance.

....Did you use the stand offs? Sorry if you did but it sounds like you didn't use standoffs. Stand offs are usually brass colored and some cases require you place them on your own as there are different motherboard types.

Make sure your standoffs are in the right spot. Any extras should be removed. Unless your case is bent you shouldn't have a grounding issue.

As long as your using standoffs you should be god with your rubber insulator.

...no. Sadly, I did not. I've put together a few other computers and did have this problem once before, but after resetting the motherboard it worked fine.....I just looked at my screws and see the stand offs you're talking about. I really feel like an idiot now, but I do appreciate the advice. I'm going to pull it all out right now and put them in, see if that keeps the motherboard from shorting. Thanks a lot, I definitely feel dumb, but I'm glad I now know...

I don't think the rubber would do any damage, but, I'd rather not find out. Thanks again.

Heat + rubber = mess
silicone is much better and can handle higher heat.

The rubber will be able to withstand the heat because similar rubber is used inside car engine compartments. But ordinary rubber should never be used for this since it's not anti-static.
