How do I upgrade the RAM in my Dell Vostro 420?
Power off and unplug the computer. Open the side panel, locate the memory slots on the motherboard. Press the clips on both sides of each existing memory module to release them if replacing. Align the notch on the new DDR2 module with the slot and press down until the clips click. Close the case and power on.

The Dell Vostro 420 supports up to 8 GB of DDR2 SDRAM, using four 2 GB modules.
Can I install a solid-state drive (SSD) in this computer?
Yes, you can replace the existing SATA hard drive with a 2.5-inch or 3.5-inch SSD. Ensure the SSD is SATA 3.0 Gb/s compatible. You may need a mounting bracket for 2.5-inch drives.
How do I clean the Dell Vostro 420?
Turn off and unplug the system. Use compressed air to blow out dust from the power supply fan, CPU heatsink, and case fans. Avoid using vacuum cleaners. Clean the exterior with a soft, dry cloth.
What type of power supply does the Vostro 420 use?

While not officially supported by Dell, many users have successfully installed Windows 10 on the Vostro 420. You may need to update drivers for graphics and other components. Performance may vary.
How can I troubleshoot no display on startup?
Check that the monitor is on and connected to the VGA port. Reseat the RAM modules and graphics card if present. Try a different power outlet. Listen for beep codes: one long beep indicates a memory issue. If none, remove all peripherals and boot.
