So I have a old pc I let a friend purchase. I got it from NZXT awhile back in 2020. I did a windows 10 fresh install, no new upgrades of any kind and all of the sudden the GPU is barely getting any load% on any games I try running on it. CPU is doing all the lifting. I'm not sure what the cause could be honestly or what resources are out there.

Parts

CPU: i7-9700k 8-core 3.6ghz but goes up to 4500 overclocked
GPU: 2070 Super Zotac
MB: MSI MPG Z390 Gaming Edge AC
G.Skill TridentZ 3200 x 2
PSU: Evga SuperNova 750w G5 Gold

Things I have tried so far as of today
-Reinstalled DirectX Legacy
-Clean Installed GPU drivers
-Benchmarked to see GPU health its good health with Unigine
-Cables are all good and health(new)
-BioS is updated to most current
-Reseated GPU

Sounds like you are running the pc on igpu, not gpu. Check connections, reseat the gpu, make sure in bios the pcie is set as primary, not the cpu.

I've never seen that in my MSI BioS. Where is it located or is there a reference you can provide? I did reseat the GPU and all connections are fine. I just don't know where the PCIe settings are in BioS.

Is your monitor plugged directly into the Super Zotac 2070 or into a connector on the back of the motherboard (iGPU)?

Somewhere in the BIOS you should find a setting which defines the primary graphics output, i.e. PCI-E (2070) or iGPU (Intel UHD Graphics 630 in i7-9700K).

Study your motherboard's user guide carefully for more details. Unless it's particularly badly written, you should find the setting in the manual.

Okay I set it to that and I'm still having bottleneck with the CPU and basically no GPU load. I also did a windows 10 reinstall. I also checked that I didn't have the monitor plugged into the motherboard itself.

Forget you ever heard that term. You don't have a bottleneck. What you have is a gpu that's not pulling it's weight. Very big difference.

Have you installed the motherboard chipset drivers After the Windows reinstall? In a reinstall, Windows essentially wipes out any and all non-native drivers.

I have installed the latest chipset for the motherboard that was on the msi website for my board. I did a benchmark test using unigine and it scored 97% in utilization so I am not sure how the card isn't holding its own weight.

Did the GPU stop sharing the load with the CPU in games as soon as you performed a fresh install of Windows, or did it work normally for a while?

If the former case is true, you might not have installed all the relevant drivers or forgot some important tweak to enable GPU acceleration.

If the computer "broke" a few days/weeks after reinstalling Windows, something must have changed. Did you install new drivers, programs, Windows Update?

So when my friend purchased the computer I did a fresh install and it worked for awhile. All of the sudden it stopped doing what it normally does. He was using it for streaming and gaming which the machine is capable of.

I'm not sure how to enable GPU acceleration if this is true. Since I installed fresh start, its been about almost two months. But the computer has maybe been used to game probably 5 times since then. When I did the fresh install I did all the windows updates at the time and drivers from intel support assistant. Now I've updated everything on the MB, GPU and even used DDU to remove old GPU drivers to make sure that wasn't the problem. Updated the BioS yesterday and turned on XMP for the RAM.

Since I just did a fresh install again for the second time. I don't have many programs on it. Xbox game app, spotify, obs studio, epic launcher, steam, Nvidia Control Panel, Gefore Experience, Intel Support Assistant.

Some programs (not games) benefit from GPU acceleration, when you manually enable it in the app.

I'm not into gaming but it occurs to me that new games might run a lot faster on a modern GPU. Your 2070 is two generations behind current technology.

Check the recommended hardware for your latest games, then consider an Nvidia RTX 4070 or an AMD RX 6950.

For 1080p a 2070Super is plenty, it'll even do acceptable 1440p @ 60Hz. It sits right between a 3060 and 3060ti in ability. It's only drawback (if you consider it a requirement to begin with) is 1st gen RTX, which was a performance killing effort.

Do you have access to any other GPU that you could swap out to see if the problem can be duplicated?
