In what lay down should I install RAM, Video Card, and DirectX?

I am getting adjectives of these at the same time, which should I install first, second, third?

In what lay down should I install RAM, Video Card, and DirectX?

Make sure your computer is bad and unplugged. Then open the computer defence. Make sure you ground yourself to prevent damage to those parts.

First: RAM (needed for computer) to an available Memory slot

Second: Video card to an available PCI or AGP slot

After that, boot to Windows, and

install Video Drivers and Direct X, afterwards reboot when Direct X prompts you to do so, and Good luck.
Ram + Video Card with computer stale. Then DirectX.
1. Ram...(Needed to install anything else)

2. Videocard...(1&2 with power stale and computer unplugged)

3. DirectX
1) go beside the RAM and video card at the same time next to the computer off (probably disconnect the power cord a moment ago to be safe)

2) install the video card drivers along with directX

3) restart you computer and soak up!
