I thought i7 didn't have a HyperThreading system because it's power enough?

In Intel Core i7 - Wikipedia (sorry in Ducth [my language])
Hyperthreading is weer aanwezig, de vier cores ondersteunen allen twee threads. Dit betekent dat zowel software als het besturingssysteem acht cores herkent.

In english:

Hyperthreading is present again, the four cores all support two threads. This means that both the software and the operating system recognizes eight cores.

Well we are at a stand still. I sent him a email and told him to go back into msconfig and change it back 1 cpu and uncheck the box. Well he changed it to one cpu and didn't uncheck the box and from that time he has nothing but BSOD.

So I tried it on my spare i7 and it was fine. It boot right back into windows and I able to change it back. We got back into windows under safe mode and he uncheck the box and it still BSOD. He even tried a system restore with no luck.

I told him I would do some more research on it but I told we might have to start from the begainning and reinstall windows again. So that is where we are at and thanks for the help. If I had the computer in front of me it would a different story. But when you dealing with somebody on the phone and 3000 miles away this is what you get.

#5 should solve the original problem.

The setting in msconfig you're talking about only slows down the machine. Very unlikely to cause a BSOD. I'm glad you could set it back using safe mode. Did he check if he sees 8 processors now?

No idea why it still BSOD's. You did a system restore... I think that should fix it.... strange.
As far as i know system restore doesn't restore the bcd store that I let him modify using bcdedit command. Maybe the extra enabled cores are faulty(?)

What BSOD did he get?

It blue screens right after the windows logo screen. That could almost be anything. SSD, Video card, MB, or Memory. Everything is brand new too.

Correct that it could be many things and I don't see the things done so far (unchecking number of CPUs, etc.) as causing a BSOD. But shipping a long distance can have consequences, even something like a video card coming loose. Suggest that the user, or someone the user knows can monkey around inside a computer, open it up and redo everything except the CPU, which I'd leave for last if its necessary.
