[SOLVED] Explorer.exe causing methodical CPU spikes

I've been trying to pin-down this issue I've been having for months and I finally think I have, yet I'm unsure how to fix it. I had thought I was having some kind of hardware fault but ruled out every single component through process of elimination with my old parts as all components are currently brand-new.

Essentially, I would notice my PC "lock up" and freeze for about a full second. It happens about every 30 seconds, very methodical, either with normal desktop use or while gaming. First I noticed it while gaming which was VERY annoying, but having it happen constantly just made it more annoying. I've ran malware tests with multiple programs, did a clean boot to check if the problem persisted without any programs auto-starting, but unfortunately it still was present.

One very important discovery was it did NOT affect my "test" local account I created. The test account showed no signs of Explorer.exe causing hang ups.

Any ideas? Will gladly try everything.
 
I get a heavy cpu spike when trying to access tom's.
I think the app is trying to access some sort of ad processor and keeps trying until about a 10 second timeout.
I get the similar thing when accessing the what's new part of the forum.
After the time, all operates as normal.

A second oddity that befuddles me is that accessing an ad gets me a unable to find ad.doubleclick.net error.
I think there is a connection.

Makes me think I could have some kind of mining virus, although why the 4-5 scanners I use wouldn't pick that up, I don't know.

Check your background apps. My recent build was doing the same thing, if I recall, and it ended up being the ASUS Gaming app that was causing it. It limited my bandwidth on things that it didn't consider games. Pull up procmon when the spike occurs and see what's running.

or might be something you install
Agreed, had thought it was a program conflicting or causing issues, however when I did a clean boot without any other services running aside from the bare Windows ones, I still had the issue. Should I attempt to just uninstall certain programs and see which is a possible culprit? I was using Process Explorer but couldn't fully understand it, the only thing I did understand was the very methodical pause caused by Explorer.exe

I had procmon running to check, definitely going to check other background apps, it's clearly something not playing nicely. I wonder exactly which program it is, if it is a program, because it still persisted after doing a clean boot...

What has a 30 second schedule??
Perhaps your email app is doing a send/receive every 30 seconds.

Do you have an app that is enabled to check for updates?
Very good question... my email app does fetch often, however I'm currently on my laptop and not experiencing issues related to that, worth a try on my desktop though.

what is bare windows ones? install any motherboard utility? gpu driver/app?
I followed steps online for a clean boot to determine any conflicting programs, so when I mean bare Windows I meant whatever that boot environment was. I don't have any utilities for CPU, GPU, or MOBO. I used them in the past but Gigabyte has SUPER clunky software and when I did a fresh install recently I purposefully didn't install them to see if they caused my CPU spiking.

SOLVED: To anyone who may read this, the issue was my desktop wallpaper slideshow changing every minute....crazy world....
Made an account just to thank you for this. was hard enough to figure out that the lag spikes were coming from explorer.exe - this was absolutely my issue.
