Asus ROG G20CB is Running Slow

Is your Asus ROG G20CB experiencing performance issues, including slow boot times, lag during general usage, and/or delayed response in applications or games? Use this troubleshooting guide to help diagnose why.

To restart the Asus ROG G20CB, click the Start menu, select the Power icon, and choose “Restart.” This will close all applications, apply any pending updates, and refresh system resources, which may help resolve temporary slowdowns. Make sure to save any open work before restarting.

The device is running slow because too many web pages (tabs) are open in the browser. Each open tab uses memory and processing power, which can slow down performance.

To fix this:

Open your web browser (like Chrome, Edge, or Firefox).

Look at the top of the window — each tab is like a small rectangle showing the page title.

Click the “X” on the right side of each tab to close the ones you don’t need.

You can also right-click on a tab and select “Close other tabs” to keep only the current one open.

The device is running slow because too many programs are open. Each program uses memory processing power, which can slow down performance.

Right-click on the taskbar at the bottom of the screen and select Task Manager.

Select any unnecessary programs.

Select End Task in the top right.

This can cause slow loading times, failure to open websites, or apps not working properly. It may happen due to Wi-Fi being turned off, being too far from the router, or issues with the network itself

Check Wi-Fi Connection:

Look at the Wi-Fi icon on the bottom right of the screen.

If it's disconnected, click it and select your network, then enter the password if needed.

If the signal is weak, try moving the device closer to your Wi-Fi router.

Restart the Router/Modem:

Unplug the power from your router/modem for 10 seconds, then plug it back in and wait a few minutes.

Right-click the Wi-Fi icon > select Troubleshoot problems and follow the steps.

For a more stable connection, plug an Ethernet cable directly from the router to the device.

When your device has very little free space left, it can slow down, apps may crash, and you may not be able to save new files or install updates

How to Fix:

Check Storage Space:

Go to Start > Settings > System > Storage to see what’s using up space.

Delete Unnecessary Files:

Remove old downloads, unused documents, or videos from folders like Downloads, Documents, or Desktop.

Uninstall Unused Programs:

Go to Control Panel > Programs > Uninstall a Program, and remove apps you no longer need.

Empty the Recycle Bin:

Right-click on the Recycle Bin icon and choose Empty Recycle Bin to permanently delete those files.

Use Disk Cleanup Tool:

Type Disk Cleanup into the Start menu, select your main drive (usually C:), and let it scan. Check the boxes for files you want to remove and click OK.

Move Files to an External Drive or Cloud:

Transfer large files like videos or photos to an external hard drive or a cloud storage service like OneDrive or Google Drive.

This means a physical component inside the computer, such as the RAM, graphics card, CPU, or cooling fan, may be malfunctioning. Signs can include frequent crashes, blue screens, loud noises, overheating, random restarts, or the device not turning on at all.

If the previous solutions have not addressed the problem, you will need to replace the CPU, Graphics Card, or RAM, please see the replacement guide linked here.
