If you want to test your PC components for performance, stability, or potential issues, here are the top 5 applications for each key component:

1. CPU: Prime95

• Purpose: Stress test your CPU and check for stability issues.
• Best For: Overclocking, detecting thermal throttling, and overall CPU performance.
• Alternative: Cinebench (for benchmarking instead of stress testing).

2. GPU: FurMark

• Purpose: Puts your GPU under extreme load to check for overheating and stability.
• Best For: Detecting thermal issues, VRAM stability, and potential artifacts.
• Alternative: 3DMark (for benchmarking instead of stress testing).

3. RAM: MemTest86

• Purpose: Checks for memory errors and stability.
• Best For: Diagnosing faulty RAM, instability, and overclocking issues.
• Alternative: Windows Memory Diagnostic (simpler, but less thorough).

4. Storage (SSD/HDD): CrystalDiskMark & CrystalDiskInfo

• Purpose: Tests read/write speeds and provides health status.
• Best For: Checking SSD/HDD performance and identifying failing drives.
• Alternative: AS SSD Benchmark (for SSDs).

5. Overall System Stability: AIDA64

• Purpose: Monitors and tests all system components under load.
• Best For: Stress testing CPU, RAM, GPU, and monitoring temperatures.
• Alternative: HWMonitor (for real-time system monitoring).
