  • Press Ctrl + Shift + Esc to open the Task Manager.
  • Click on the Processes tab and look for applications using high CPU or RAM.
  • Right-click and select End Task to close these applications.

Optimize Startup Programs

Too many programs starting at boot can slow down your computer.

  • Open the Task Manager again.
  • Navigate to the Startup tab.
  • Disable any unnecessary applications by right-clicking and selecting Disable.

Consider Hardware Upgrade

If performance issues persist, consider upgrading your hardware. Tekklina offers PC building services tailored to your needs.

2. Connectivity Problems

Troubleshooting Network Connection

If you're having trouble connecting to the internet:

  • Right-click the Network icon in the taskbar.
