To install additional RAM, first power off the system and unplug all cables. Open the case by pressing the release button and removing the side panel. Locate the RAM slots on the motherboard. Insert the RAM module into the slot at a 90-degree angle, ensuring the notch aligns with the slot. Press down until it clicks into place. Reassemble the case and reconnect all cables.
Check the power cable and ensure it is properly connected to the power outlet and the back of the tower. Test the power outlet with another device to confirm it is working. If the issue persists, inspect the power supply unit (PSU) for any signs of damage. Replacing the PSU might be necessary if it's faulty.
To reset the BIOS, power down the computer and unplug it. Open the case and locate the CMOS battery on the motherboard. Remove the battery for about 5 minutes, then reinsert it. Close the case, reconnect the power, and boot the system. This will reset the BIOS to default settings.
Ensure that the computer is placed in a well-ventilated area. Open the case and clean any dust from the fans and heat sinks using compressed air. Check that all fans are operational. Consider applying new thermal paste to the CPU if the problem persists.
First, try connecting the mouse and keyboard to different USB ports. If they are still unresponsive, test them on another computer to rule out hardware failure. Update the USB drivers on the OptiPlex from the Device Manager. If the issue remains, check for any BIOS updates.
Turn off the computer and disconnect all cables. Open the case by removing the side panel. Locate the hard drive bay and remove the screws securing the drive. Slide the old drive out and disconnect the power and data cables. Connect the new drive, secure it with screws, and reassemble the case. Reconnect the cables and boot the computer.
Ensure the monitor is powered on and the video cable is securely connected to both the monitor and the computer. Try using a different video cable or monitor to rule out these components. If the issue persists, remove and reseat the video card. Updating the video drivers might also resolve the problem.
Power down the computer and unplug it from the electrical outlet. Open the case to access the interior components. Use a can of compressed air to carefully blow out dust and debris from the fans, motherboard, and other components. Avoid touching the components directly. Reassemble the case after cleaning.
Upgrade the RAM to the maximum supported capacity to improve multitasking. Consider replacing the hard drive with a solid-state drive (SSD) for faster data access speeds. Regularly clean the system to prevent overheating, which can throttle performance. Keep the operating system and drivers up-to-date.
Back up all important data before proceeding. Insert the installation media (USB or DVD) into the computer. Restart the computer and press the F12 key to access the boot menu. Select the installation media from the list. Follow the on-screen instructions to install the new operating system, ensuring to format the drive if required.
