To install additional RAM, first power off and unplug your ASUS S640MB. Open the side panel of the case by removing the screws. Locate the RAM slots on the motherboard. Align the new RAM module with the slot and press down firmly until it clicks into place. Reattach the side panel and power on the system to check if the RAM is recognized.
First, ensure that the power cable is securely connected to both the power outlet and the power supply unit. Check the power switch on the back of the unit. If the system still does not power up, try swapping out the power cable or testing the outlet with another device. If the problem persists, there may be an issue with the power supply unit itself.
To update the BIOS, visit the ASUS support website and download the latest BIOS version for the S640MB. Save the file to a USB drive. Restart your computer and enter the BIOS setup by pressing the designated key during boot (usually F2 or DEL). Use the EZ Flash utility in the BIOS to select the file on your USB drive and follow the on-screen instructions to complete the update.
Slow performance can be caused by various factors. Start by running a virus and malware scan. Check for and uninstall unnecessary programs. Ensure that your operating system and drivers are up to date. Consider upgrading your RAM or switching from an HDD to an SSD for better performance.
To replace the hard drive, power off your system and unplug all cables. Remove the side panel of the case. Locate the hard drive bay, unscrew the old drive, and disconnect the cables. Install the new drive by connecting the cables and securing it in the bay with screws. Reassemble the case and boot up the system to ensure the new drive is recognized.
Ensure that your graphics card supports dual monitors. Connect each monitor to the graphics card using the appropriate cables (HDMI, DisplayPort, etc.). Go to your computer’s Display Settings to configure the monitors, setting one as the primary display and arranging them as desired.
Turn off your computer and unplug it. Remove the side panel. Use compressed air to gently blow dust from the components, focusing on the fans and heatsinks. Use a soft brush to remove stubborn dust. Avoid touching any components directly to prevent static damage. Reassemble the case once clean.
To reset the CMOS, power off the system and unplug it. Locate the CMOS battery on the motherboard. Remove the battery for about 5 minutes and then reinsert it. This will reset the CMOS settings to default. Alternatively, use the CMOS jumper if available by following the specific instructions in your motherboard manual.
Overheating can be caused by dust buildup, inadequate ventilation, or failing fans. Clean the internal components to remove dust. Ensure all fans are operational and consider adding more case fans or upgrading the CPU cooler if necessary. Ensure your case is placed in a well-ventilated area.
Check if the graphics card is properly seated in its slot. Ensure that all power connectors are securely attached. Update the graphics drivers to the latest version. Test the card in another system to rule out a hardware issue. If problems persist, consider contacting ASUS support for further assistance.
