I'm seeing strange visual glitches, like flickering lines and distorted colors, on my monitor, especially when I'm playing games. I suspect my graphics card might be failing.

In your computer's Bluetooth settings, remove (unpair) both the headphones and mouse, then put them back into pairing mode and re-pair them.

Use the built-in Bluetooth troubleshooter in your operating system's settings to automatically detect and fix common Bluetooth problems.

Open the Services application, find 'Bluetooth Support Service', and restart it. Ensure its startup type is set to Automatic.

Temporarily turn off other wireless devices in the vicinity to see if the connection improves.

Move your computer and Bluetooth devices closer to each other and away from potential sources of interference.

Uninstall the current Bluetooth drivers from Device Manager and then restart your computer to allow Windows to reinstall them automatically.

Go to your computer manufacturer's website or the Bluetooth adapter manufacturer's website to download and install the latest drivers.

A technician can test individual components to pinpoint a hardware failure.

If the laptop is under warranty, reach out to the manufacturer for potential hardware diagnostics or repair.

Search for 'Calibrate the screen for pen and touch input' in Windows settings and follow the on-screen instructions.
