My GPU only working at 30% after moving

[Nal]

I just moved yesterday with my computer. Before moving, my computer was working perfectly fine. Absolutely no problem, always super fast. Now that I plugged it at my new place, when I opened my favorite game, I saw that it was super slow. Unplayable. And when I tested other games, it was the same. Too slow. And the games I tested are on multiple drives and it’s still super slow. When I opened my task manager, I saw that the GPU was only working at 30% when usually it works at 100%. What surprises me is that every game I tried is really slow but when I tried Blender (a free open source 3D program), everything was just fine and my GPU was working at 100%. I went to the graphics settings on windows and all my games at set to high performance and I also changed global settings in NVidia control panel for the power settings. I also tried Benchmarks and it says that my GPU is perfectly working. I don’t know what to do anymore and I would really like some help.
These are my specs:

CPU: i9-10900F
GPU: RTX 3060 12gb
Storage: 500gb NVME SSD
500gb HDD
1tb HDD
RAM: 32gb

Hello

Power down the pc ,unplug and then drain the pc of power by pressing the power button . Go inside the case and check for any loose components.. Ground yourself by constantly touching the metal case.
