In Device Manager, a network adapter shows a yellow exclamation mark next to it. Which action should you take first to resolve the issue?

Disable and re-enable the device to reset its state.

Uninstall the device and restart the computer to force a fresh driver install.

Replace the network adapter because the yellow mark means the hardware is dead.

Open the device's Properties and review the Device status field for an error code.

A user reports that a new graphics design application crashes on startup. The system has a 64-bit processor, 8 GB RAM, and a dedicated GPU with 2 GB VRAM. The application requires 16 GB RAM and 4 GB VRAM. Which action should you take?

Upgrade the system's RAM and GPU to meet the application's minimum requirements.

Reinstall the application because the installation may be corrupted.

Check the power connection and ensure the GPU is seated properly.

Lower the application's graphics settings to reduce VRAM usage.

Replace the motherboard because the LED is off.

Check the power button connection to the motherboard.

Test the power supply using a power supply tester or swap in a known-good PSU.

A user's desktop PC will not boot. The power LED is on, but the screen is blank and there is no beep. The user recently installed a new graphics card. Device Manager is not accessible because the system does not boot. What is the best first step?

Reseat the RAM modules because memory issues can cause no beep.

Replace the power supply because the new graphics card may require more power.

Remove the new graphics card and use the onboard video to see if the system boots.

Check the monitor's power and video cable connections.
