Hi @sethismail

What applications are you running?

Possible Causes

- Overheating (most common)

- Dust buildup inside the case or laptop vents blocks airflow.

- Thermal paste between CPU/GPU and heatsink has degraded, reducing cooling efficiency.

- Fan is working overtime to compensate, hence the loud noise.

- Background Processes / Memory Leaks

- Some applications or drivers may consume more RAM/CPU over time, causing the system to slow down and eventually freeze.

- After a reboot or long cooldown, performance temporarily returns.

- Hardware Issues

- Failing cooling fan or clogged heatsink.

- Hard drive/SSD problems (especially if the system hangs and takes hours to recover).

- Power supply instability.

- Software/Driver Problems

- Outdated GPU/CPU drivers can cause overheating or improper resource management.

- Malware or unnecessary background apps can keep the CPU running at high load.

What You Can Try

- Check Temperatures

- Use tools like HWMonitor, Core Temp, or MSI Afterburner to monitor CPU/GPU te
