The type of FireWire connection in use (motherboard or expansion card) is not going to make your interface "noisy". Incorrect FireWire drivers or settings could cause pops and drop-outs in the audio, but not noise. Persevere with this FireWire connnection, as changing to connecting through a PCIe card is not going to solve anything unless the drivers for the PCIe card happen to be more compatible with V64.

If you bought this PC as recently as you say, did it not come with the option of a Widows7 upgrade?

Maybe what others can learn from this is: do your homework before purchase!

Are you sure that it doesnt have PCIe slots? They're really small compared to standard PCI and there are several sound cards that will work with them I think, MOTU for one.

PCI slots/cards are different than PCIe slots/cards. They are not compatible with each other.

What is the model/service code of the Dell computer you purchased?

"which is currently occupied by a graphics card. "

AGP...

edit.
You are bitching at the wrong people...we could care less how the makers of computer products are shrinking these items.

Let the buyer be aware.

Well, it turns out they were PCIe slots. The old PCI had been going for so long, I wasn't expecting the change. There aren't many cards out yet that are PCIe. Dell said to upgrade the bios and that should fix the Firewire noise. They said they were aware of the problem and it had been fixed. I haven't actually downloaded the upgrade yet to see for myself.

As it is my Presonus Firebox, Emu PCI card, nor Cubase SX3 run on this computer and I was just so worked up that I angrily posted this.

I know I can't expect companies to keep from innovating and that my stuff will all become obsolete someday. I guess I can't complain. I guess I'm a real jerk. Thanks for pointing that out... last guy who posted. I know you are probably a more logical, rational person than I am and lead a more fulfilling life, free from anxiety about trivial things. I want to be more like you.

I do have a free upgrade to Windows 7 and maybe I'll get lucky and my Firebox and Cubase SX3 will work on it. I was thinking of getting a Motu MK3 to replace the Firebox... but not if I can't fix the firewire problem with the bios update. I haven't tried it yet since Cubase doesn't work anyway.

I suppose Dell sells decent products at a reasonable price. :)

I am going to just keep all my old equipment around and if I can't get my newer faster machine to run it, I'll just stick with that. I don't want to spend a thousand more just to get back to where I am already just so I can run more plugins at once on my CPU. There are ways around limited CPU power of course.

I still fail to understand how the firewire driver affects the audio signal.

If the signal is not dropping out or clicking then any static noise must be caused by analog components and not the part that transfers digitally.

Maybe that's the programmer in me assuming that some of the recording chain works as documented.

I downloaded the new bios and hopefully that solves it. It almost seemed like something wasn't grounded. It sounded like it might be the monitor amps, but they didn't have that problem with the other computer. There are two Firewire ports. I could try the other one.

I see at MicroCenter that the PCIe Firewire cards cost a lot more than the old PCI ones. The one I saw was like $40. I hope I can get away with the built in one.

I may just have to keep recording on my 2003 PC 2.6 PIV because I don't feel like buying new software, new soundcard interface thingy and perhaps even new plug-ins.

I love how fast the new machine is. It will even edit my HD home videos, but none of my recording stuff works... yet. Probably never will.

I had read that I could run Cubase SX3 on Vista in Virtual PC mode. I got the program running on Virtual PC but it will not see my Firewire Firebox. I read that it can not see Firewire devices in Virtual PC. Then I saw that a PCI card should work fine, so I popped in an old Emu 0404 I had laying around and tried that only to find that there were no old fashioned PCI slots. Foiled again. Maybe I'll buy Cubase 5 in a couple of years if I am still recording semi-regularly. It's just a hobby, but I want it to sound good or there is no point. The old computer and Firebox seem to have problems when recording. Sometimes it studders and I have to rerecord the whole track. I have to turn off plug-ins and such to reduce CPU and memory strain. Annoying. It won't even play back an MP3, WAV or CD without a few skips and studders in there. This new machine is smooth as silk- but nothing works. Oh well. At least I can use it for other things. I have a switch and can switch between the old and new pc in a second. That's convenient.

95% of my PC use is non recording anyway. It's just nice to have something new work without having to replace everything else along with it. At least I can use my mics, guitars, and amps.
