I would make them buy the whole thing back. Shop for a properly spec'ed super machine from one of these sources:

1. Sweetwater music: http://www.sweetwater.com/creation_station/
2. ADK: http://www.adkproaudio.com/
3. Rain computing: http://raincomputers.com/products/

There are other companies as well to consider, but these folks have already worked out these type of issues from the get-go. These are boxes spec'ed just for high-demand audio work (for which Richard isn't even doing - he's not doing 50+ tracks of I/O - but the kids at the Micro Center don't have a clue which was made crystal clear when they piped back what the PreSonus was).

No, the computer you buy from one of the above will not seem to be spec'ed as highly in some performance areas as the spec-it-yourself method, but you will not have to deal with the issues that Richard is dealing with now. These are ground-up spec machines for audio work. Gamers need not apply - go buy your alienware and clone boxes with neon lights inside from someplace else.

Richard - unless you have lots of personal content to move back off the machine, demand your money back - that would be my advice.

It really blows that you are dealing with this after the excitement you posted about finally getting a new box.

For my next music box, I'm buying from one of the above 3 or I'm joining the dark side and going Mac. I've had to fart around with Windows 7 driver issues on my new lappy, and was able to get it to be functional and fun with my recent Tascam US800 purchase, but I don't get enough time to do this hobby any longer to waste another second trying to sort things out myself. This Samsung lappy I bought about 9 months ago now decides now and then it just doesn't like to work for anything - even simple office function. I've exorcised it 6 ways to breakfast with all manner of anti-malware and anti-virus, etc. At least with an Apple, the boxes are designed ground-up for I/O, musicians in mind - and I've got a 'Genius Bar' less than 5 miles from the house. Cost will be about the same - properly spec'ed and supported PC from one of the above 3 or a Mac with similar performance features. Choices are more limited, but I'm getting crotchety about choice lately, give me fewer choices, just those that work and thank you I'll be recording and editing.
