Random Lag / FPS Loss

[ouroboros16]

Hi. So I started having random lag/fps loss some 6 months back while browsing, youtube or playing games. I tried everything from taking the PC apart, cleaning everything to reinstalling windows. After this, on another forum I was suggested that this was an fTPM issue, but from whatever videos are there on the web, I'm not sure if my issue is the same. The lags last longer when I'm not playing games; during games this issue mostly starts when I go back to the game from pause menu (or any other menu) and I have to restart the game to fix this. For some games (mostly Betheda's - Skyrim and FO4), alt-tabbing fixes this.

 

My specs-

Ryzen 5 1600

Rog strix GTX 1660ti

16gb 3000 Hz RAM

500 gb SATA SSD

1 TB NVME

Corsair RMX 650

144 Hz AOC 24-inch monitor

Windows 10

 

Attaching a video from Arkham Knight to show you what I mean.

 

Anyone else experienced the same? Can this be a setting which is turned on/off?

 

PS - The lagging is not just in games, but also during normal windows operations.

Take a look at your task manager or something like MSI afterburner and tell us your CPU usage and temperature and GPU usage and temperature, when this happens.
This way, you can find out, which component is maxed out, you can see thermal problems like bad thermal contakt between CPU and cooler and maybe we find out, what causes this.

Did the game run smoothly before with the same settings and resolution?

So took the attached screenshots from the Task Manager just as it happened.

Hmm, we can't see the CPU temperature, but so far I can't see anything bad.

I will install Afterburner and share CPU temps soon

 

EDIT: I installed Afterburner. The temps seem normal but I saw a spike in the GPU usage during the systems lags. See the usage info in the bottom right of the screen below:

Bump

 

After checking a couple of times more, GPU is hitting ~90% usage during the lags (both inside and outside of games). Please help!

It was the ******* riser cable! I removed it and plugged the GPU directly in the motherboard and all issues are gone. It's been one week now, lag-free.
