New Computer Woes, Not sure how to troubleshoot what's broken.

Was building a new desktop for my Sister's boyfriend, it's been a while since I put together a custom rig and I suppose I'm just out of practice.

We got a closed system heat sink for the processor but the mounting hardware was damaged, so we toss it back in the box, RMA it after the weekend or get the hardware replaced, whatever happens happens.

Then we get to the issue at hand, I finish putting together the computer, using the stock heat sink from Intel, get the computer all wired up, boot it up (running a small backup VGA monitor off onboard graphics instead of the GPU, for the purpose of getting the OS and drivers installed etc...)

About 50% of the way through the installation process the screen goes haywire, candy cane lines etc... So I assume it's some sort of issue with the monitor, nah turns out it's the computer. So I shut it down, remove the GPU just in case it was some driver install conflict, boot back up into mini XP off a flash drive, let it run for a bit, same thing.

So I attempt to restart immediately after and it goes into a boot loop, it'll start up and seem to short out before anything even gets started.

Now it'll sometimes go candy cane at the select boot device screen. I'm not really sure how to troubleshoot what's broken here, I double checked all my wiring and am confident that everything is where it's supposed to be (I really can't think of anything I COULD miswire to cause something like this) which leaves it being a processor problem, a motherboard problem, or a PSU problem...

Any ideas on what I could test? Anyone ever experienced this before?

http://www.newegg.com/Product/Product.aspx?Item=N82E16819116895 - Processor

(the MOBO and Processor may not be the exact models as I couldn't find the specific order for the parts, but they're in that general product line/range.)

Thanks for any thoughts.

I should make note I've tried everything in the troubleshooting thread as well including breadboarding but this only seems to happen at the point of actually testing where I can actually look at everything fully assembled.

After breadboarding everything, I'm debating splitting the difference and just telling Newegg that both the Processor and MOBO were DOA since I can't properly verify which one is actually not working.
