Solved Trying to diagnose a crippling computer-wide stutter.

Specs: Windows 7
Hi everyone,

For the longest time, my PC desktop has had a stuttering issue, where it seems like the system freezes for a moment, often a few times in a row. It doesn't seem to be an issue with a specific program, as it is agitated by quite a few programs, such as Cubase 8, iTunes, YouTube, Netflix. Games often elicit this behavior as well. But at the same time I can tell it's happening as I type this post with nothing else running, as the movement of my cursor is stuttering too.

A video where the stutter happens a bunch right away:

An audio example of a small stutter at 1:38:

I've checked the performance and processes tabs on the windows task manager, and it didn't seem to acknowledge the skips at all (videos of this below).

The device manager seems to think that my audio drivers are up to date, so I'm not sure that's the cause either.

The issue has been getting worse, and has especially worsened since I moved to a new apartment last week. I also made the egregious mistake of shipping it a long distance only to find that the CPU fan had detached and was bouncing around loose in the case. All this leads me to suspect a hardware issue, but I'd appreciate any help in further troubleshooting this problem or pointers as to which piece of hardware could be the culprit.

Specs are:
Windows 7 64-bit desktop (Home Premium)
Processor: i5-4670 CPU @ 3.40 GHz
RAM: 16 GB
3TB HDD, 250GB SSD (running Windows and Cubase)
Graphics card: AMD Radeon R7 200 Series

Thanks so much in advance :D

Any decent quality thermal compound will work in all but the most extreme conditions. The MOST important part here is tp do it properly. Please look over this for your CPU:

You have to be a little bit crazy to keep you from going insane.

The CPU load is relatively high, although that shouldn't case problems unless your CPU starts to overheat and the thermal protection kicks in.
You mention the CPU fan was loose. How did you repair this issue? Did you reapply thermal paste? (first clear the old paste and residue then apply new paste?

Check the temps with this little app:

Start the sensors before you start your music app. It should register temps and possible thermal protection activity.

Hey, so I did not reapply thermal paste, and I definitely think that's a possible suspect. I just thoroughly eliminated drivers as a suspect today (used hwinfo for that), so I think I'll address this next.

Thanks!
