How to Build a Computer from Scratch: The Complete LIFEHACKER Guide


Lesson 1: Hardware Basics

Building a computer from scratch gives you the perfect machine for your needs, but it can be daunting the first time around. For our first lesson in building your own PC, we start with a little computer hardware basics.

Lesson 2: Choose and Buy Your Parts

In this lesson, we'll show you how to most effectively pick out and shop for your parts.

Lesson 3: Building the Computer

Assembling your computer can seem daunting, but it's actually pretty easy. In lesson 3, we show you step-by-step how to put everything together.

Lesson 4: Installing Your Operating System

Once you've put it together, you're past the difficult portion. Lesson 4 deals with installing your operating system and get everything up and running.

Lesson 5: Further Resources

There's a lot more computer-building info out there than we can fit into one Night School. In our final lesson, we share some other resources that should help you in both the building and post-building steps.
If you'd like all of these lessons in a printable PDF file, click here to download one. That way you can take it with you to the store, to your workbench, or anywhere else you may need it.



To more efficiently install all the usual goodies —Firefox, LibreOffice, VLC Media Player, Gimp, Dropbox, AVG Free and Skype, to name a few—I turn to the first tool, Ninite (, a utility that automates the process of downloading and installing software.

To use Ninite, simply visit the site, choose the applications you want to install, and download and run the Ninite installer.

A real time saver, Ninite spares you the trouble of hitting the Next button again and again on different installers, and automatically rejects offers to install toolbars and other junk programs.

A Ninite installer always gets the latest version of the applications you choose, no matter when you downloaded it. To update installed software, simply run the Ninite installer again.

Software choices are fairly extensive, with support for four popular browsers, nine messaging clients, 15 multimedia programs (including iTunes, Winamp and VLC), seven runtimes and plug-ins (including Flash), seven imaging applications, eight office productivity packages (including MS Office, OpenOffice and LibreOffice), seven anti-virus and anti-spyware programs and more than 30 other utilities.

10 Windows keyboard shortcuts you need to know

You may already know about CTRL+ALT+DELETE and ALT+TAB, but what about the all-important F1 key? And what happens when you hit the shift key five times? Read on for 10 keyboard shortcuts that every Windows user should have at their fingertips.


The last resort (well, besides the power button) for many a Windows user after a program freezes on the desktop, this essential three-key combo call up the Windows Task Manager, which lets you pinpoint and close a misbehaving application.
Note: on Windows 7 systems, CTRL+ALT+DELETE calls up a screen with other options besides launching the Task Manager, including locking the computer, switching the current user, and logging off altogether.

2. ALT + TAB

Here’s another keyboard shortcut every Windows user should know. Press ALT+TAB to call up a rectangular window with icons representing your currently running programs; just “tab” over to the app you want, then hit Enter to make the switch.

3. F1

Need a little help? Tap the F1 key at the top of your keyboard to launch a Help window for the application you’re currently using, or for Windows in general.

4. CTRL + ESC, or the Windows key

Gives you instant access to the Start Menu; just use the arrow keys to navigate to the program, directory, or option you want, then hit Enter to select.

5. ALT + F4

Closes the active window you have open, such as an open Internet Explorer window. Also, if the window you’re closing is the only one that’s open for a given program, the app in question will go ahead and quit.

6. Windows key + the “E” key

Launches Windows Explorer, the essential desktop browser for all the applications, directories (like your personal Windows user directory), documents, and other system files on your PC.

7. Windows key + “M” key

Need to see your desktop this instant? Use this keyboard combo to minimize every open window at once, thus revealing the Windows desktop.

8. Windows key + SHIFT + “M” key

So, you found that missing file on your desktop, and you’re ready to dive back into that Excel chart. Now what? Strike this trio of keys to restore all the windows you just minimized.

9. Windows key + “L”

Sends you instantly to the Windows lock screen, perfect for hiding your work (or your Facebook wall) during a quick trip to the restroom.

10. Pressing the SHIFT key five times

So, what exactly does striking the shift key five times in rapid succession get you? Well, it’ll turn on a Windows feature called “Sticky Keys,” which lets you press the shift, control, “alt,” or Windows keys one at a time rather than all at once—handy for anyone who has trouble dealing with complex keyboard combinations.

If example-based tutorials are your preferred method of learning, Android Cookbook is a great (free) resource.
