Decision Guide
Can You Fix It Yourself, or Do You Need Help?
DIY fixes:
Disabling startup programs, clearing storage, running Malwarebytes, and a factory reinstall are all free and effective for software-related slowness.
Needs a tech:
If the PC is slow even after a clean reinstall, or if you're seeing hardware errors in Device Manager, the issue is likely a failing component.
Worth repairing?
Use our Repair or Replace Calculator to decide whether upgrading makes more sense than buying new.
