- Ensure the correct input source is selected on your monitor.
- If using dual displays, try connecting only one monitor at a time to isolate the issue.
- Verify RAM modules are correctly seated.
- System Not Booting / OS Issues:
- Confirm that the storage drive (SSD/HDD) is properly installed and connected.
- Check BIOS/UEFI settings to ensure the boot order is correct and the storage drive is detected.
- If the operating system is corrupted, you may need to reinstall it.
- No Network Connection:
- For wired LAN, ensure the Ethernet cable is connected and the router/modem is working.
