New computer from Dell - anyone ever experienced this problem?

Stormy: that's the exact case. The only thing I don't have is that black and red module on the bottom of the case.

The media module in question is actually on top, right in between the PSU (top left) and the optical drive (top right). The gap in the middle there is where that module is. There's no doubt something is amiss. The original was possibly bad but with the replacement exhibiting the same problem I'm starting to think it's a design issue as oppose to the actual component. Another thing we can't understand is why I get the USB cable disconnected message during start up when in fact all the USB cables are connected. There are three USB ports on top and only one is working even though all three are connected. So it's possible that the original one was fine after all, the replacement was faulty, and it's just a bad design by Dell.

Keep in mind this isn't a new issue with Dell desktops apparently. Through Google I found that back in 2003 people were reporting the same problem with some Dimension models. The workaround then was to plug the headphones/speakers directly to the motherboard or sound card. So Dell's so-called engineers were aware of these interference issues 8 years ago. And still, the same problem is happening today.

Update: So, I got the new system delivered today and found it's making the exact same noise as the old one. At this point, it's clear that this is a design defect. To all those who are considering purchasing the same system, watch. After two brand new systems and a replacement of the module by a technician including the wires connecting it to the motherboard, it's clear that this particular model is defective.

Dell's workaround is to plug the headphones/speakers to the back of the system. But this is, in my view, unacceptable considering the system is brand new. Apparently, this is a known issue with other Dell systems.

Dell's technical support have been completely useless. I'm speaking to one rep right now who asked me to make the kind of noise the system makes. WTF? When I told her it's distortion noise and electrical hum whenever the headphones are plugged into the top module, she said she doesn't know how to actually add it in the notes.

I could return it for a full refund but everything else works fine. I'm thinking of keeping it and driving them hard for a sizable credit as well as upgrading the warranty to their most top of the line one.
