Stuttering stuff is nearly always due to CPU activity, often antivirus. You'd need to report from Task Manager what the CPU loading is pon the various listed processes whilst all this stuttering is happening.

Yeah - but what does Task manager report?

You go to Task Manager/Processes.
Click at the top of CPU column twice.
The processes that are using the CPU are listed in descending order of consumption.
I'm asking you to list the top three, say.

I should have said - watch the task Manager pane and note what's up in the top three when the stuttering happens evry 4 or 5 minutes.
Let's say it's every 5 minutes. What have you got set to happen at that interval? Mail poll? And does AV kick in to scan incoming mail? Is it every 5 mins?
You can see where I'm heading.
Oh - I forghot to say - looking at your HJT file, try stopping DFRGNTFS and see if the problem goes away. I believe that comes in periodically.

OK - I've looked into DFRGNTFS. That only shows in Task manager if you are defragmenting your drive. Presumably it's not showing now.
When this happens, what are the top three process CPU usages in Task Manager? If it is CPU interruption, and if you're quick looking at this, it'll be the best clue to what's going on.
What about AppleMobileDeviceService.exe or iPodService.exe? Is that set to have a look round every 5 minutes?
You can disable it by doing Start/Run/services.msc
TYhen scroll to Apple Mobile Device & hit the Stop service. Then see what happens every 5 minutes. if that does the trick, we can work out later what to do with this service that presumably you'd like to keep going.

It's the mouse thing in your first post that tells me that there's something interrupting your CPU every few minutes.
According to your last post whenever this happens, no additional program appears in the Tsk Manager top three CPU usages. You've also said in an earlier post that no CPU spikes of that frequency can be seen in the performance logs. Frankly, this has got me stumped.
Have you measured the exact periodicity? If it is always the same, then we can have a look at the settings of everything in your HJT list.

This likely means that CPU services are being called from elsewhere, like the graphics card, although I can't think of what is actually happening.
So we have to leave the PC quiet (no audio/video); have the graphs visible; measure the exact periodicity so as to form a view of its significance or otherwise; and listen to the disks or whatever to see if there is anything else consistently happening; plus look at the screen to see if there's a jolt.
This is the sort of thing then that an expert needs to have in front of his/her eyes!
