Performance Optimization: RAM usage high with no apps open
4.5
Memory usage is at 80-90% even when the desktop is empty.
Symptoms
- Stuttering
- Low memory warnings
- Slow multitasking
Possible Causes
- Memory leak
- Bloatware
- Superfetch/SysMain issues
Step-by-Step Fix
1
Check Startup Apps
Disable unnecessary apps in Task Manager > Startup.
2
Restart SysMain Service
Restart the SysMain (formerly Superfetch) service.
3
Scan for Malware
Some miners hide their memory usage from Task Manager.
When to See a Technician
If Task Manager doesn't show where the RAM is going, it's likely a "Non-paged pool" leak caused by a driver.
