I have a three year old Dell machine that works really good but a month ago it started giving me problems.

When it's running through my system under amplification if I touch the keyboard I get a desperate feedback/static....really loud.

I've tried it with the external card and the internal card and it happens both ways. When it's just running by itself the problem doesn't occur.

It's not the wires I changed them and used them after that on the backup lappy.

Any ideas?

Ground misbehavin'??????
 
Key word "amplification" ;)
 
I have 2 new Dells with 2 prong plugs and I have no problems with any noise. I also have 2 HP's with the ground and as soon as I plug them in I get the damn noise so the adapters come on and problem solved. I also have 2 Vaio's with the 2 prong plgs and I've never had a problem with them either.
 
I only have like 3 outlets in the entire building with 3 prongs, so almost all my gear is through adapters -- no problems until I use the grounded ones.

You don't need it on a lappy, cause the power supply isolates you from the AC, and at most, yer getting 20 volts DC to the lappy.
 
It's two prong coming of the lappy going in to the Power Conditioner and out to the wall.

I wish I could describe the sound it makes it's not a buzz it's more like a loud scratch that doesn't let up

Is Rob, Adam or Thunder around...? yorofl:
 
Is this while running VDJ???
 
No Mixmeister pro 6
 
I'm trying to find a way to describe the noise....Somewhere between white noise and feedback...Very loud regardless of how high the pot is up. I would almost think it was the cord but it seems to work fime on the other lappy and it happened with two different cords (1/4 to 1/8).

Only happens when I touch the keyboard. First happened a month ago, went away, and happened again last Saturday. First time it happened it was only when I touched the right side of the keyboard last tome it was when I touched anywhere near the keyboard
 
Clean the KB with anti static spray????
 
can you record the sound and post it for some to listen too ?

might give some ideas on how to stop it (I know I would if I heard the sound)
 
Could it be one of the solder connections on the headphone out going bad... or the jack itself? Might explain why it is only on jack output and would also explain why it gradually gets worse and responds to pressure on different parts of the casing/machine?
 
Don't touch the keyboard. OK, I know I'm a smartazz.

This is the first time I've heard of this.

Have you tried an antistatic matt?
 
Some (most?) keyboards have a ribbon cable connection. This may or may not have a plug on the end. The type that doesn't uses a pinch connection to connect to the PC and that can work itself loose over time. I would find the keyboard removal process, remove & re-insert the connector.
