I just got a refurbished gaming PC with specs like the Ultra 7 265kf CPU, an RTX 5080 graphics card, and 32GB of DDR5 6000MHz RAM. Everything was smooth during setup, but now it feels sluggish. It takes forever for files to open, and web pages load slowly. After digging around, I discovered that the CPU cores are locked at 400MHz due to something called PROCHOT. A specific temperature sensor on my motherboard is acting up, showing fluctuating temperatures between 40°C and 107°C in HWInfo64. Before I consider returning the PC under my 2-year warranty, I'm hoping there's a simple solution I might be overlooking.

Was your Windows operating system pre-installed, or did you install it yourself? Sometimes, pre-installed software can cause issues. If it was pre-installed and you're having problems with the NZXT CAM or Nvidia apps not updating, you might consider doing a clean install of Windows. That way, you can ensure you have the latest drivers and proper software settings.
It sounds like you're experiencing something called PROCHOT, which means your PC is detecting overheating and automatically downclocking the CPU to prevent damage. This is often due to poor thermal contact. Check if the thermal paste is applied correctly and ensure the heatsink is actually making contact with the CPU. If there's a water cooler, make sure the pump is functioning. This overheating isn't just a sensor glitch; it's likely an actual issue with heat management.
