Troubleshooting Sudden Memory Usage Spikes Leading to System Lag
Encountering system performance issues can be frustrating, especially when your hardware specs suggest smooth operation. Recently, I experienced a situation where my computer’s memory usage would max out, causing noticeable lag and hitching, similar to the behavior of an older laptop with limited RAM. This issue affected both general usage and streaming services like YouTube, which would hitch but not buffer smoothly.
Symptom Overview
- Significant lag and hitching during regular tasks
- System behaving as if RAM is exhausted, despite not seeing high memory consumption in Task Manager
- The problem appears to initiate after opening Visual Studio Code (VScode)
System Specifications
- Processor: AMD Ryzen 7 7800X3D
- RAM: 32GB DDR5
- Graphics Card: NVIDIA GeForce RTX 4070 Ti S
- Storage: 2TB SSD (with approximately 160GB free)
Initial Diagnostics
To investigate, I monitored the Task Manager before and after the issue started. Here are some relevant observations:
- Memory Usage: Not consistently high during lag periods
- Background Processes: No obvious culprits consuming excessive memory
- Open Applications: Behavior seems linked to opening VScode

Possible Causes and Troubleshooting Steps
Given these symptoms, several potential causes and resolutions can be considered:
1. Check for Memory Leaks in Applications
Some applications, notably development environments like VScode, can sometimes cause excessive memory consumption due to extensions, plugins, or misconfigurations.
Action:
- Monitor memory usage per process in Task Manager or Resource Monitor
- Disable or uninstall extensions in VScode to identify if one causes leaks
2. Investigate Background Processes
Unnecessary background processes may consume memory or system resources, contributing to lag.
Action:
- Use Task Manager or Process Explorer to identify and disable unneeded processes
- Prioritize resource-intensive tasks and close unused applications
3. Verify System Stability and Updates
Ensure your system is up-to
