New Upgraded PC Stutters on desktop, typing, and in game

I upgraded my Motherboard, CPU, and RAM yesterday and have had constant issues since doing so. The build should have 0 issues running high end AAA games, however I'm having issues running my desktop, web browsers, or even League of Legends without stuttering, FPS drops, and other problems.

It lags while typing in the address bar on chrome, it lags on alt tabs, and it lags in game. It doesn't do it 24/7, but I have no idea what is causing it.

My PC is a Ryzen 7 2700X, Liquid cooled by a Kraken x62, with 16 GB of 3000 speed RAM, a GTX 980ti GPU, and windows on an SSD. This build should have 0 problems running anything at 2560x1440, but I can't even maintain 120hz @ 1920x1080.

The CPU never gets above 50 degrees when the stutters happen, and the GPU never gets above 80 degrees (in fact, it was happening at 60 degrees). The CPU usage never goes above 40%, the memory usage never goes above 50%.

I just know that randomly, I'll either be in game, or on my desktop, and everything I do lags slightly. Typing will skip some frames, and catch up to me. Alt tabbing takes slightly longer.

The strangest thing is, the FPS drops are actually very regular. In Elite Dangerous, I drop from 120hz (the max cap I set), to 80hz. It does this over and over again, on a seemingly regular interval of about 1 second. It seems consistent with what happens in other games too. Its a regularly timed FPS drop, then spikes right back up to where I max it out at.


I'm so confused and have no idea what to do and need help from anyone who can give it
 
If you changed motherboards, you need to reinstall Windows. The lag you're describing is common when Windows has drivers for missing hardware or corrupt drivers. Those drivers hang, and Windows waits for a timeout before killing and restarting the driver.

If you did reinstall Windows, double-check to make sure you have all the drivers for the motherboard and other hardware installed. If you don't install drivers, Windows goes back to fallback drivers, which may not work as well. Windows 10 has gotten better about finding and installing appropriate drivers, but it still screws up a lot. Manually installing the drivers is still your best bet.

It's not quite as important to reinstall Windows after a CPU upgrade. Windows can usually detect the change and make adjustments. But you're still safer reinstalling.

RAM upgrades don't require a reinstall.

If you really don't want reinstall, and prefer to troubleshoot what's going on, check the Windows error logs to see what's failing. You'll probably find it flooded with error messages corresponding to each time the computer lags.

I've already done a clean install of Windows, but kept my files. And I've manually downloaded my BIOS drivers. And its not constant. Like now, I'm not experiencing the stuttering while typing, but I was just after running a semi-intensive game. That led me to think it was a bottleneck or overheating issue, but none of my components even get past 50% Usage (unless its the GPU mid game), and heat is fine across the board
