New Build Keeps Stuttering

[Crusher21]

I just finished building my first computer, it has the below components.

 

A few times a day, the computer will freeze up for about 7 seconds and then unfreeze like nothing happened. At first I thought it was the display driver but when I sent my 1080Ti back (because I decided to go with an RTX 2080 instead), during the time I was using the onboard graphics I still had the same stuttering. I suspected it may be the bios so I upgraded to the latest bios version, 1.60 (from 1.51), but still experienced the same stuttering.

I am not doing any CPU intensive tasks. My 2080 is not here yet so I'm still using onboard graphics. I also purchased another 16gb of the same RAM, that will be arriving tomorrow.

I'm not sure what to do next. Every time it freezes, I check Event Viewer and see no indications of any problems. I don't know if there is monitoring software that I could install to help diagnose this but I'm sure the software would freeze too during the stutter. Any help would be appreciated.

Is there anything specific that causes this to happen or is it pretty random? Also double check that all your mobo drivers are up to date

[Crusher21]

It's pretty random. There was one time where it stuttered right as I tried to access an internal HDD that likely wasn't spinning since it hadn't been accessed in awhile by me, but I think that was a coincidence. All my drivers should be up to date.

[Crusher21]

I just checked my temps in HWMonitor and my computer stuttered again while opening the GUI. Task manager showed a momentary 100% cpu utilization spike. Temps are fine though.

[Crusher21]

Theoretically, if I had my computer plugged into a surge protector that also had several other devices connected to it, could a stutter be caused by the surge protector not always being able to provide enough power to the power supply?
Background: In the past, I had plugged in six external hard drives into a high joule-rated surge protector and was trying to diagnose why sometimes some drives would appear in windows and othertimes they wouldn't but new drives would appear. I ended up coming to the conclusion that the surge protector couldn't handle all the drives at once. Plugging some into one surge protector and the rest into another one fixed the problem. Right now I'm experimenting to see if that is the problem. I'm waiting to see if the computer stutters.

Sounds like something is maxing your cpu randomly. Did you try a fresh windows install?

 I haven't done that since, after all, it's pretty much already a fresh install of windows. Could there be a conflict between Kaspersky and Malwarebytes?

Try disabling them and test it, if you have a spare hdd/ssd I would put a clean install with only basic software like drivers and afterburner for monitoring to see if you still have issues.

I know this is an old thread, but did you find a solution?
