Understanding Sudden Performance Issues in Your PC: A Comprehensive Troubleshooting Guide

Experiencing unexpected performance issues with your computer can be frustrating and confusing, especially when symptoms appear suddenly and without clear causes. If you’re facing system stuttering, crashes, freezing, black screens, or Blue Screen of Death (BSOD) errors, it’s essential to approach the problem systematically. This article aims to help you diagnose and resolve common hardware and software issues that could be affecting your PC’s stability.

Your System Specifications

To better understand potential causes, here’s an overview of your current setup:
– Motherboard: ASUS ROG STRIX B550-A GAMING
– Processor: AMD Ryzen 9 5900X 12-Core
– Graphics Card: KFA2 RTX 4070 12GB
– Memory (RAM): Corsair Vengeance RGB 16GB x2 (total 32GB)
– Operating System: Windows 11

Common Symptoms and Their Possible Causes

Your description indicates several issues:
– System stuttering, freezing, and black screens
– Crashes and BSOD errors, notably “WHEA_UNCORRECTABLE_ERROR”
– Driver-related errors with the Huion graphic tablet
– Performance drops during gaming sessions or heavy multitasking

These symptoms can stem from multiple sources, including hardware failures, driver conflicts, system misconfigurations, or software bugs.

Step-by-Step Troubleshooting Approach

1. Addressing the Blue Screen Errors

The “WHEA_UNCORRECTABLE_ERROR” points toward hardware issues, often related to memory, CPU, or power supply abnormalities. Here’s what you can do:

Run Hardware Diagnostics: Even if initial memory tests (such as MemTest86) seem complex, they are critical for identifying RAM issues. Consider using user-friendly tools like Windows Memory Diagnostic:
Press Win + R, type mdsched.exe, and hit Enter.
Choose to restart now and check for problems.
Check Temperatures and Power: Use hardware monitoring tools (e.g., HWMonitor, Ryzen Master) to observe CPU, GPU, and system temperatures under load. Overheating can cause system instability.
Update BIOS and Drivers: Ensure your motherboard BIOS is up-to-date, as BIOS updates often resolve compatibility issues and improve stability.
Inspect System Files: Running the System File Checker can help repair corrupted system files:
