The Problem:
This computer is lagging at random. The lag makes anything (windows desktop or in game) choppy. The mouse will start jumping around like crazy. I noticed on the CPU meter that i jump from 4% to up to 30-40% CPU at random. Almost like its randomly spiking.

I have built several i7 platforms now and haven't even seen these things come close to lagging out.

This computer was the most expensive of them all so far and this is driving me nuts. This is also a computer I built for a friend and I feel awful that he is having these problems.

The bios setting are default and i'm not running any overclocking (at least that I know of)

Any suggestions?

Clear the BIOS using the procedure in the motherboard manual.

Strip everything down to a bare bootable configuration.

Remove one video card, 1/2 of the RAM, both optical drives, and the wireless adapter. Replace the keyboard and mouse with generic parts. Then see what happens.

I suspect that the system will work normally. Then gradually add components, testing after each step.

My one friend had a nearly identical setup that would do the same thing. I can check to make sure, but I'm pretty sure it ended up being his memory. Try running just a single stick and see if that helps...

You can also download Linux (try Linux Mint) to a CD and boot from that without installing it. See if it does it in Linux. If not, it's a software problem.

You guys are not going to believe this...
I started removing the parts (memory,video card, etc) one by one and the problem was still there. finally I remove the wireless adapter for the hell of it and the problem goes away. I don't understand how that wireless card could have caused all of that. I just did not believe it, so I ran the computer fine for a bit and decided to put the card back in. This time I put it in a x16 slot and it seemed to work fine. Then I had problems connecting to the Internet and out of no where the lagging problem came back. So I removed the wireless card again and the computer started running like a dream again.

Now that the computer is running smooth -- load up a few games and the whole computer shuts down after a few mins of play. So, I figure its overheating. So I install a second display to monitor the temp while I'm in game. The CPU was running fine at cool at 40C when it crashed several times.

I noticed that the bios was flaging the case fan speeds RED. It did not seem to like the RPM speeds, lol. So I turn off the system fan speed monitor and the system stoped crashing...

Now everything is running tip-top. No overheating, no crashing...

Wow, that was days of BS... lol

Thanks for all your help guys!
