Component List:
CPU: Intel Pentium Processor G3258 @ 3.20GHz (2 cores)
MOB: MSI H81M-P33
RAM: 8GB of Crucial Ballistix Sport (4GB x 2)
HDD: 500GB Western Digital Caviar Blue @ 7200rpm
PSU: EVGA 500W ATX Power Supply
WIFI: Rosewill RNWD-11011 Wireless Adapter
Audio: Avid Fast Track Solo (Using proprietary ASIO audio drivers.)

Recently, I've consistently had an issue with my audio stuttering and dropping out during playback. This happens in editing software like Ableton Live or Pro Tools, streaming services like Spotify Youtube, and Netflix, and also just regular playback from Media Player. The stuttering most reliably occurs whenever I click, change, or load something new, but not always. Examples:

1. While streaming from Spotify, if I open Chrome or browse to a new page, audio will stutter.
2. While creating music in Ableton Live audio will randomly stutter and sometimes Ableton freezes.
3. While watching Netflix, audio and video will freeze and stutter more and more frequently until Chrome crashes.

I've tried numerous things: Reinstalled all kinds of drivers, disabled various services and the wifi, ran the computer in safe mode, increased audio interface buffer, monitored latency (no abnormal latency), tried playing audio via headphones, used a different audio interface. No improvement.

Today I tried something new: I monitored CPU usage via Task Manager and found that not always, but often, the stuttering would correlate with spikes near 100% usage. I tweaked around with this again, trying to see if there were some competing services that were doing this, but I found none. I then wondered if overclocking my CPU would help by possible increase my processing power overhead. (To be clear, I do know I have a Pentium Core, but this setup has never given me a headache before, and has always ran all of these programs just fine, even Pro Tools. The CPU seems to be just as zippy as ever, and does everything else at regular speeds. It only seems like audio has been having problems.)

That's when I discovered the weird part: Upon opening my BIOS, the CPU temp read a constant 99° Celcius! Just to double check, I downloaded a temp program and it measured at a lower level fluctuating between 78° and 83°. Still very high, but considerable a discrepancy? I switched off my computer and took it apart. I have several fans; the whole system is well ventilated and not very dusty. The only thing I can think is that my thermal paste needs to be replaced? Essentially my questions are:

1. Because this problem has been on going for several months, it's likely the CPU has also been operating at these temps. Have I damaged my CPU? If so, that's not a huge deal as I got it for free, but why can it do all other tasks normally?

2. Obviously my CPU has been running too hot, but is this possibly correlated to the audio problem? It seems like a stretch, but still possible?

3. Besides the thermal paste, what else could be causing those temperatures? It seems to me that those temperatures are very high to be caused by just year old thermal paste?

Any help on this issue would be much appreciated! Thanks in advance!
 
Solution
1. Probably not, if it's still booting it's probably still ok.

2. Perhaps, if the CPU is throttling down because it's overheating. It could also be due to the service that Windows uses to manage priorities for media playback.

3. 78 to 83 on load isn't unusual if you're using the stock cooler (they're not very good), but if those temperatures at at idle they are pretty bad. Old thermal paste is generally not a problem, unless it's totally dried out and I don't think I've ever actually seen dried out thermal paste on a CPU that was installed for less than 10 years. The idea that thermal paste degrades very quickly is generally not correct.

If you removed the heatsink the paste needs to be replaced, any time you remove the heatsink you...

If you removed the heatsink the paste needs to be replaced, any time you remove the heatsink you have to replace the paste. Also, check to make sure the CPU fan is actually spinning.

I would not run this computer until you are sure that it is not that hot.

First, boot into the BIOS/UEFI. Does your mother board show the CPU temps? What are they?

Try downloading Open Hardware monitor and see what it reads.

1. I'm not a CPU expert but if it was running that hot I'm amazed that it is still running.
2. I'll let others respond.
3. Too much paste will cause it to run hot. Not enough airflow in your case. If you have a small case with small 80mm fans it can add to the problem. But not 90C type of hot unless you have no airflow. Also, if your CPU fan/heatsink is not mounted properly. Properly as in it is not centered on the CPU. Some fans are hard to attack and if it is off-center it won't do much. I don't think too many people think of that. Having and AMD CPU and a 'highly recommended' fan I have a hell of a time getting it in properly.

If the open hardware monitor shows it at 90C I would not be running it until I find a solution.

As for the sound, if the CPU is trying to lower the voltage to prevent overheating(I don't know if this CPU / motherboard will do this) it might be a cause of the freezing and break up.

I wouldn't like to see this CPU above 70C.
Good luck.

Dmitche3, First the 99° reading came from the BIOS and the 78° to 83° reading came from software while fully logged in, etc. And second, you may have figured out the problem, when I went to go look at the CPU, I found the heatsink and fan unit was not completely attached, which means that it must not have been aligned with the processor correctly.


Quixit, I didn't realize that I had to replace the thermal paste if I removed the head sink/fan! I think I probably took it off around 2-3 months ago to clean it, which seems to about correlate with the start of these audio issues. I'll get some new thermal paste asap.

In summary, it appears the problem might have been that I, a while back, removed the heat sink to clean off the dust and not only failed to reapply the thermal paste, but also didn't correctly reseat the heat sink when I was done. This must have lead the thermal paste to dry out even more quickly. (Looking at the thermal paste now, it's bone dry!)

I will go get some thermal paste tomorrow, see if that resolves the issue, and then post back when I have some updates.

Thanks all!

That's not true. If you put too much thermal paste, when you mount the cooler the excess will end up on your motherboard. And even if you manage to keep a thick layer of paste, as long as there are not pockets of air, you're fine.
