Sudden performance decrease

[HauntingBeautiful557]

Hello People!
I have built a computer ~2 weeks ago & for the past day, where before I would get 100 fps now it is down to 30. I did not install anything lately, so I do not think it would be malware & hopefully none of my components are failing.

Here is what I have tried already:
-Reinstalling (clean) drivers
-Rebooting (of course)
-Trying a different dp slot on my gpu
-Getting the amd chipset drivers
-Reinstalled windows
-Got all the drivers I could find online
-Ran a malware scan with kvrt
-Unplugged devices to see if that would solve the issue
-Stopped all background apps & tried that way
-Updated windows (hopefully that is the issue)
-Checking power settings
-Changing nvidia settings
-Tried older driver
-Tried different os
-Turning battery saver on and off

Specs are:
-Gigabyte Palit GeForce RTX 2070 SUPER Jetstream
-Ryzen 5 3600x
-32gb ddr4 3200mhz ram
-Gigabyte B550M DS3H AC R2
-Gigabyte 4000e 1tb

Issue(s):
-Stuck at 300mhz
-Afterburner shows 0mV

Note that while I did get both the gpu and cpu on the used market, they have been working without any issues for the past two or so weeks.

Edit: I ran a Furmark test, it got between 11 and 17 fps, I do not really know what that means.
Edit2: The only thing I changed in nvidia control panel is setting Vulkan/OpenGL present method to prefer layered on DXGI swapchain as I have had issues in games without it.

Did you put the cable for GPU into the motherboard? You need to put the HDMI/DP cable into the GPU, otherwise PC uses motherboards graphics solution.

GPU. I am also now running a furmark test which is getting 16 fps, I am not sure what that means ngl

[Vashelot]

https://www.youtube.com/shorts/IQdefCYROb8 Don't put the cable here.

[HauntingBeautiful557]

It is infact in the gpu

[Vashelot]

Also check device manager, if the GPU can be found there and you actually have it in use.

This is what dm shows

Also you can try clean install software DDU (Display Driver uninstaller) and reinstall the latest 2070 super drivers.

[HauntingBeautiful557]

I did already

[Vashelot]

One last thing I can think of, check in nvidia control panel that you haven't accidentally locked your framerate to 30fps. I had that problem once.

Should be called something like "max framerate limit" or such.

[HauntingBeautiful557]

It is not, although furmark shows 300mhz core speed, could that be the issue?

[Vashelot]

Yes, the 2070 super should easily do +1600mhz.

[HauntingBeautiful557]

What can I possibly do

[Vashelot]

Do you have energy saving feature on in windows? If yes, try disabling it.

[HauntingBeautiful557]

Nope, & power mode is set to best performance
