Overview - what this guide covers
We’ll show you quick steps plus PC-Care.ai automation to keep video calls smooth.
Symptoms you might see
- Video freezes during screen share
- Audio lags behind
- CPU spikes to 90% during calls
- Battery drains quickly
Freezing and lag signal CPU saturation or GPU encoder issues. Audio lag shows buffer underflow. High CPU spikes from background apps plus Zoom encode load.
Manual fixes - step by step
- Update graphics and audio drivers
- Close unused browser tabs and heavy apps
- Enable hardware acceleration in Zoom
- Disable background updaters
- Use High Performance plan during calls
- Run PC-Care.ai to trim startups
Driver updates reduce DPC latency. Fewer tabs free CPU cycles. Hardware acceleration shifts encode load to GPU. Disabling updaters prevents random spikes. Performance plan ensures CPU headroom.
Prevention - keep the issue from coming back
Before important calls, reboot and open only essential apps
Keep Zoom updated to benefit from performance improvements
