Continuous Stuttering in Vista

Specs: Windows Vista 32-bit
I have a problem that I have been struggling for weeks to figure out. I built my computer a year ago, and it worked great until about three weeks ago, when it suddenly started skipping every 3 seconds. I first noticed it with playing audio and thought because the audio file was on my second HD and the audio program was on my primary C drive. However, I soon realized that this constant stuttering would occur every 3 seconds, and the CPU usage would jump from 0% to 3 or 10% when it happened. Even the mouse would freeze and hiccup every three seconds. I reformatted the computer and the problem is still happening. It does not happen in Safe Mode, which makes me believe that it is some sort of driver issue, but I cannot seem to figure out what is causing it. I have tried uninstalling my video drivers and others, but it persists.
I need help! I have coworkers stumped by this problem as well and have not been able to find a solution on the web.

Watch Task Manager & see which process is using the CPU when it stutters.

There are no processes that stand out in CPU usage when it stutters, that was the first thing I tried. At first, it looked like the stutter may have been an issue with wmpnetwk.exe, which is the Windows Media Network Sharing Service. Also, explorer will sometimes jump to 15% CPU usage without any real explanation.
When the stutter occurs, there seems to be some sort of reaction across the system. Even Firefox and Symantec may jump in usage sometimes when the stutter occurs.

UPDATE:
It seems that the most I can isolate the stuttering issue, it seems to either be cause or effect a rather large jump in CPU usage by explorer.exe, even when no explorer windows or anything are open. Sometimes the usage will jump to over 25%, which seems very strange.

So this happends after a fresh format without anything installed on it as well?

If it doesn't it's a program that you have installed that is causing the problem within explorer.

Do you have the hard drive set to shut down in the bios at a specified time?
Does this happen when your network connections are disabled ?

It did happen after a fresh format, but only after I began to install drivers again. Unfortunately, I was not able to pinpoint what driver it was that was causing it. I thought that if I installed all the drivers slowly and one-by-one, that I may be able to isolate the driver, but I wasn't able to figure out what it was. It is my belief that it may be the Nvidia drivers or the networking LAN drivers built into the motherboard, but I have tried uninstalling these to no avail. And of course, the problem goes away in Safe Mode.

I will check the bios HD settings, but I'm pretty sure it is not set to shut down at all. I have tried switching Sata cables on my raptor HD, and I think I may try a new sata cable for my secondary HD as well, to see what that does.

The issue is not always constant. Sometimes, I can listen to music for a few minutes, but then it will start its stuttering again. If I watch a video of anything (even streaming off a website) it will usually begin its stuttering. It does seem like it may be something network related, but I have tried uninstalling network drivers a few times. I disabled the LAN drivers, since I run off of wireless, but the problem continues.

UPDATE: I have noticed a considerable increase in explorer crashes, even when doing basic procedures like opening a file folder containing a few items. It seems like the root of the CPU usage and such seems to be coming from explorer.exe, but how can that be? Is there something that is overloading explorer? That's the only thing I can think of at this moment, but I am still having a ton of trouble tracking down whatever is causing explorer to glitch out.

Strike that... the stuttering occurs in safe mode, as well
