I am looking for some way to shield my Soundcard area from the Graphics cards to cut out the interference. I have googled geegled gaagled and have found no info on where to buy this or if there are other methods, any help is appreciated.

Im wondering if you couldn't use the anti static bags that the electronics stuff comes in. Just use it to seperate them maybe. Just got to be careful with shorts and stuff like that.
Anti-static bags sound like a good idea. Move your cards as far away from each other as possible...

Also try switching your GPU to the lowest slot.
EMI Shielding? Build a Faraday Cage! Custom cut an aluminum sheet to fit around the card and then ground the sheet.

There's something called ERS Paper that can be purchases as well... but I think that's snake oil.

Lol, then i would have a bomb shelter in my computer
Not a bad idead though just sounds crazy any pics?

That's a good thought, but im looking to make something a lot nicer.

I wanted it because I got a 1.5 TB HD (Seagate) and I have a 100 GB IDE that is retired. But I triple-backed up all my photos and videos on it. want to take it offsite (car trunk, work - wherever fire can't get to it).

So fire it taken care of, so EMP's are the only thing I'm worried about. Now IF (Big big big if) terrorists ever got their hands on Emp-pulse bomb - but also from the cosmos - I'd like to find decent Emp-sheilding myself.

I have it in a static bag now... but I don't have confidence it would actually help against EMP's....it's for static.....

keep the ideas coming folks....

Wouldn't a faraday cage be opposite of what we need (from Ghost Hunters I'm thinking)....

Which bring up MY suggestion... use physics... create an EMP field around whatever you're trying to protect (the above dude's faraday idea maybe?? - sorry if I'm stealing your idea and putting it in laymen's terms).. with sufficient data, everyday occurances and a non-direct terrorist emp strike can probably be shielded against... I think catastrophic cosmic events would still get to it though.

but if that happens... keeping my digital photos will probably be the least of my worries

my shield idea.... in this theory - emp waves aimed - outward...nullifying inbound emp pulses.....

problem (what's to shield from the shield).....can you really direct the waves easily without feedback (the original posters main goal)
I would think a metal mesh would work, just ground the mesh to the case.

is it padded? if not, youll kill it from the daily hits of bumps

anyway, EMP shouldnt wipe a harddrive, it would render it inoperable while emp is in effect, otherwise you need strong magnetic forces to wipe or screw with a harddrive

ERS paper simple and cheap

Why? It would destroy all his other components and still wouldn't protect from all EMI/EMP frequencies. Faraday Cage would almost completely protect from EMP already.

Metal mesh works for a Faraday Cage... as long as the gaps aren't larger than the wavelengths you are trying to block.

Questionable physics... and an aluminum shroud would look cooler! (a la Asus Xonar)

Correct me if i'm wrong but was Gill not trying to shield agains terrorist style EPM, that wouldnt cause enough of a magnetic force to wipe a hard drive? so what would be the point of the attack?

You need to buy ERS PAPER, you can get it at percy audio.

Thanks Thome - yeah, as to the hard drive and magnetism.... I do believe the M in EMP is magnetic, making it a very realistic thing to lose data on a hard drive (in theory)..

back to faraday... my point was, what's to shield from the shield itself. I've never heard of a magnetic field that's one way..but I'm not a physicists, so I hope you bear with me here...

I agree with you that it would destroy everything inside, that's what I'm trying to prevent. Aim the cage's energy outward, but you'd still have to protect what's inside. My limited physics knowledge (2 courses in high school, 2 in college for a political science major isn't too bad) seems to indicate that the energy would work both inward and outward unless it is specifically directed outward. So how do you do that? In effect, you'd be creating shielding for the shield itself.

So keep em coming, this is a good discussion. probably more than this dude wants... but we're helping pave the way for the death star here folks (in ROTJ, not the concept model in New Hope)

And for all wondering what EMP events I'm saying could wipe out data:

1.)Terrorist strike *unlikely
2.)Cosmic event *very likely
3.)Natural occurance *kind of unlikely

If we could guess at the energy this strike or event would take, obviously we would guard against it. Since we don't - that's the point of this - how can we effectively shield for EMP's (whether inside a computer like this original poster wanted - or larger scale like I'm looking for).

In either case, the theories everyone is providing and concept behind them will help both of use - and all of you interested readers. And like the orignal poster, I looked all over the net too and couldn't find anything. And no, I do not hang out with any physicists unfortunately (otherwise I'd be constructing a time machine instead of liquid-cooling my PC).
Is it necessary? I only ask because in my rig I have my Audigy 2 in my PCI slot right above my topmost PCIe x16 slot that holds my 9800GTX. I haven't had any issues, but was just wondering because this thread made me

.... what? A Faraday Cage is all this is needed for EMP. No other shield is needed against EMP since a Faraday Cage covers almost all forms of EMP.

Lol.. "Faraday Cage"... now there's a term I have not heard in awhile.

You guys never cease to amaze me.

Seriously.
