Did I break my PC? 
So this is a rather long story, and I'm genuinely very sad about this, but I'll try to keep it short:
CPU: 7800x3D
GPU: 7800xt sapphire nitro
PSU: Corsair 850rmx shift
Motherboard: B650 Asus Gaming plus wifi
CPU Cooler: DeepCool AK620
SSD: Samsung 990 Pro
Cooling: Arctic P14- 3 frontal Case-Fans, 1 on the rear
So I built my new PC after saving money for months. I flashed the bios, I installed win11, I installed all the drivers, enabled expo, and everything worked fine, smoothly.
Then I was going to run some benchmarks. I wanted to start with memtest86. So I downloaded the tool from their website that prepared the USB-Stick for it and I ran it. I selected the same USB stick that I used for the windows install (I didn't change anything about that USB-Stick yet). The memtest86 tool said that it would delete all the files on the USB-Stick.
When I ran the tool, my PC suddenly froze. I waited and waited, but my PC froze completely, I couldn't even Ctrl+alt+del into task-manager. So I pulled out the USB-stick, and the screen started showing some weird stuff, (as if the GPU was dying or so, parts of the screen were black, parts of it were weird).
So I...turned off my PC with the PSU button. I turned it on again, and... It did boot, but suddenly many of my windows settings were changed, everything worked slower, FanControl (the open source application) had a weird bug where it wouldn't detect many fans again, citing issues with the fan sensors ("27 fans should be detected, but only found sensors for 22", or something like that. I could be wrong about the numbers tho). Also, the refresh rate of my monitor was changed, and I couldn't even select it in Windows anymore. Before it was 165hz, and now it only let me select 60hz.
So I did a fresh reinstall of windows from a newly prepared USB-Stick, I did format the SSD beforehand, and now... The PC still runs badly
Issues are:
- Fans randomly go fast while I'm doing next to nothing.
- When I open HWinfo, the CPU cores all show yellow bars on the left and fluctuate all the time (back then, they were all green bars) and I also noticed that the GPU info about the frequencies and all fluctuates like crazy.
- And everything works considerably slower on the PC now, like much slower. Before that it was super fast, now everything has a delay.
I'm so mad and sad and I don't know what to do. I saved all my money, and now...this. I won't be able to afford a new PC for another couple years lol.
