About

HeavyLoad is a free Windows stress-testing tool that pushes your PC to its limits by maxing out CPU, RAM, disk, GPU, and network resources to test system stability, cooling, and reliability under extreme loads

Key Features:

- Multi-Component Testing: Simultaneously stresses CPUs (all cores), GPUs (via 3D rendering), RAM (physical/virtual memory allocation), disks (read/write tests), and networks.

- Real-Time Monitoring: Graphs CPU usage, memory availability, disk space, and FPS during tests.

- Customization: Adjust test intensity per component, set duration, and define free-space/memory thresholds.

- "Maximum Terror" Button: One-click full-system stress test
