Unpack the desktop and connect the power cable. Connect a monitor, keyboard, and mouse. Press the power button to turn on the system. Follow the on-screen instructions to complete the Windows setup process.
Check all power cables and ensure they are securely connected. Try a different power outlet. If the problem persists, reset the BIOS by removing and reinserting the CMOS battery.
Turn off the desktop and unplug all cables. Open the side panel of the case. Locate the RAM slots and insert the new RAM module into an available slot, ensuring it clicks into place. Replace the panel and reconnect the cables.
Regularly clean dust from the vents and fans. Keep the operating system and drivers up to date. Perform regular virus scans and backups of important data.
Ensure the Ethernet cable is connected properly. Check the network settings in the control panel. Restart the router and the computer. Update the network adapter driver if necessary.
Ensure your desktop's graphics card supports multiple monitors. Connect each monitor to the appropriate video output. Adjust display settings in Windows to extend or duplicate the desktop across monitors.
Ensure the desktop is in a well-ventilated area. Clean dust from the fans and heatsinks. Check that all fans are functioning properly. Consider applying new thermal paste to the CPU if overheating persists.
Back up all important data. Access the recovery options by pressing F8 during startup. Select "Repair Your Computer" and choose "Dell Factory Image Restore" to restore the system to factory settings.
Check the desktop's power supply capacity and available space. Popular compatible options include the NVIDIA GeForce GTX series and AMD Radeon RX series, depending on the model's specifications.
Increase RAM, upgrade to an SSD for faster storage, and ensure all drivers are up to date. Regularly clean the system of unnecessary files and optimize startup programs.
