Overview - what this guide covers

We’ll cover driver updates, background app trimming, and PC-Care.ai automation.

Symptoms you might see

Fan noise constant
Idle desktop uses high GPU
Games stutter despite high FPS
System hot even in standby

A pegged GPU can come from crypto miners, stuck hardware acceleration, or broken drivers. Stutter despite FPS means frame pacing issues.

Manual fixes - step by step

Check Task Manager GPU usage tab
Update GPU drivers
Disable hardware acceleration in apps
Scan for malware
Trim startups with PC-Care.ai
Reinstall GPU driver with clean install

Task Manager shows which process uses GPU. Driver update fixes leaks. Disabling hardware acceleration can drop idle usage. Startup trimming ensures only needed apps load at boot.

Prevention - keep the issue from coming back

Run PC-Care.ai monthly to keep GPU idle clean

Review GPU usage after driver updates

How PC-Care.ai helps

PC-Care.ai finds GPU heavy processes and schedules them off peak.

The scan also flags outdated drivers.
