If you have a USB mouse, unplugging the USB connection and plugging it in again sometimes wakes the mouse back up.
If restarting doesnít work, check the Device Manager, which displays any conflicts and offers some fixes or suggestions. Hereís what to do:
1. Open the Control Panel.
2. Open the System icon.
3. Click the Hardware tab.
4. Click the Device Manager button.
The Device Manager window lists all your PCís hardware, as shown in Figure 13-5. The item labeled Mice and Other Pointing Devices contains information about your computerís mouse.
5. Open the item named Mice and Other Pointing Devices.
You see beneath that item an entry for every mouse or pointing device installed on your computer. (Yes, you can have more than one.)
The first thing to notice here is whether the mouse hardware is flagged with a yellow circle and exclamation point. If so, the hardware has definitely gone haywire; continue with Step 6 to see what specifically is wrong.

6. Open your mouseís hardware entry to see its Properties dialog box.
The Mouseís Properties dialog box appears. Any known trouble is listed in the Device status area. You can also use the Troubleshoot button on the General tab to help diagnose mouse maladies.
If you need to change the mouseís device driver, click the Driver tab and then click the Update Driver button. Heed the wizardís instructions to properly reinstall or update the mouse driver.
7. Close the Properties dialog box, Device Manager, and other open windows when youíre done.
In my travels, rarely have I had to install any specific mouse device drivers. Itís really Windows itself that controls the mouse. The only reason to reinstall or update a mouse driver would be to use any special, nonstandard features on the mouse, such as extra buttons or ďInternetĒ buttons.
Oh, and those wacky nonstandard mice ó including the infamous 3D flying mouse ó they need their own software to do their tricks.
^ Mouse pointer jumping around? Hard to control? See ďCleaning the mouse,Ē later in this chapter.
^ Your laptopís mouse is typically a touchpad. Yes, you can install an external mouse on your laptop, in which case it sports two pointing devices.
You can find software for the various breeds of the Microsoft mouse at the Microsoft download center, at www.microsoft.com/downloads/.
Logitech mouse support is on the Web at www.logitech.com/.
170 Part II: Troubleshooting Minor Irks and Quirks
Your mouse is getting s-l-o-w
Mice can slow down if theyíre dirty. Consider cleaning your mouse, as discussed later in this chapter. A more common cause is simply age. Old mice slow down. They get crappy. They break. Kaput.
If the mouse is older than about four years (sometimes not even that old) and itís getting frustratingly slow, replace it. Buy a new mouse. That fixes the problem.
Beyond fixing the slow mouse problem, nothing is more satisfying than repeatedly pounding the mouse into the table with an aggressive fist.
Monitor Madness
Monitors are possibly the most peaceful of computer peripherals. Unless, of course, youíre watching a science fiction TV show from the 1960s. In that case, the monitor is most likely the thing that explodes whenever the computer becomes confused. But thatís mere fiction! Ha-ha.
Monitors donít explode. They implode. And, thatís only the CRT (cathode ray tube) type of monitor. LCD monitors donít explode or implode. But, the CRT monitorís glass encloses a vacuum. If you poke a hole in the monitorís glass ó thwoop! ó implosion. I donít feel that I need to devote any space here to troubleshooting that problem.
Beyond the rare CRT implosion, your monitor rarely, if ever, screws up. No, itís the image on the screen that bugs you most of the time. Those problems are covered in Chapter 6, in the section about the display being stuck in dumb mode. For now, hereís a small assortment of monitor hardware problems:
The monitor buzzes or hums. Monitors buzz and hum naturally. Loud humming can be a problem, however. If the humming distracts you from doing your work, repair or replace the monitor.
Connections get loose. If the image is missing or appears in all one color or ďweak,Ē check the monitor cable. Ensure that one end is snugly plugged into the monitor and that the other end is snugly plugged into the PC.
