Determine the Manufacturer and Speed of Your Processor (CPU) The processor — also known as a CPU—is the part of your com- puter’s hardware that performs the tasks handed out by your software.

Right-click the My Computer icon on your desktop. If this icon is not available, click the Start button in the lower-left corner of Windows and right-click My Computer.

Determine Your Hard Drive’s Size and Remaining Space A hard drive is a piece of equipment that stores all of the programs and data on your computer (think of it as a digital warehouse). If your hard drive has too much information on it, your computer can become noticeably slow. If the hard drive becomes completely full, you will be unable to install new programs or download files from the Internet until you free up some space.To determine the overall size of your hard drive and how much room it has left, do the following: 1. Double-click the My Computer icon on your desktop. If this icon is not available, click the Start button in the lower-left corner of Windows and click My Computer. If you can’t find the My Computer icon anywhere, do the following: a. Right-click in the empty space on your desktop. b. Select Properties. c. A window opens. Click the Desktop tab. d. Near the bottom of the window, click the Customize Desktop button. e. Another window opens. On the General tab, beneath the words Desktop Icons, place a checkmark in the My Computer box. f. Click OK. g. You are returned to the previous screen. Click Apply. h. Click OK. i. The My Computer icon appears on your desktop. Double-click it. 2. A window opens. Right-click the icon for the hard drive you want to check. For example, if you want to know the size and remaining space for your C: drive (which is the drive that most people have Windows installed on), right-click the icon labeled C:. 3. Select Properties. 4. A window opens. On the General tab, you should see the words Used Space.This indicates how much of your hard drive is being used.You should also see the words Free 140 Part III • Bonus Material 18_068557 ch12.qxp 12/13/06 6:17 PM Page 140 Please purchase PDF Split-Merge on www.verypdf.com to remove this watermark. Space, which indicates how much room is left on your hard drive (see Figure 12-5). Both of these numbers will be expressed in measurements of gigabytes (GB) or megabytes (MB) — for example, 500MB or 2GB. Don’t be alarmed if you see that your gigabytes have a smaller number than your megabytes; a gigabyte is much larger than a megabyte (1 gigabyte is equal to 1,000 megabytes). Figure 12-5: Hard Drive Properties window Open Your Computer’s Case After you have used Windows to do a quick analysis of your PC’s primary features, you should open the computer’s case and examine the equipment inside. Becoming comfortable with opening the case and identifying the components is essential if you ever want to per- form a hardware upgrade on your own. 1. Turn off your computer and unplug it from all electrical out- lets.This will prevent you from receiving a serious electrical shock and will protect the computer from being damaged. 2. Examine your case to find out how it opens. Some cases have a removable cover shaped like an upside-down “U” that slides off when some screws are unfastened. Other cases have side panels (or doors) that slide off or swing open when they are unscrewed or when a special button is pressed. 3. If you cannot figure out how to open your computer’s case, check the owner’s manual or documents that came with your system.
