If the problem occurs when both the keypad overlays are off, 
make sure the software you are using is not remapping the 
keyboard. Refer to the software’s documentation and check 
that the program does not assign different meanings to any of 
the keys.
You have connected an external keyboard and the 
operating system displays one or more keyboard error 
messages.
If you have a second keyboard, try it. If it works, the first 
keyboard may be defective or incompatible with your 
computer.
Display problems 
Here are some typical display problems and their solutions:
The display is blank.
Display Auto Off may have gone into effect. Press any key to 
activate the screen.

Disk drive problems 
Problems with the hard disk or with a diskette drive usually 
show up as an inability to access the disk or as sector errors. 
Sometimes a disk problem may cause one or more files to 
appear to have garbage in them. Typical disk problems are:
You are having trouble accessing a disk, or one or more 
files appear to be missing.
Make sure you are identifying the drive by its correct name 
(A: or C:).
Error-checking
Run Error-checking, which analyzes the directories, files and 
File Allocation Table (FAT) on the disk and repairs any 
damage it finds: 
To run Error-checking:
1Click Start, then click My Computer.

❖Automatically fix file system errors
❖Scan for and attempt recovery of bad sectors
6Click Start.
Error-checking runs the test.
Your hard disk seems very slow.
If you have been using your computer for some time, your 
files may have become fragmented. Run Disk Defragmenter. 
To do this, click Start, then click All Programs, point to 
Accessories and System To o l s, and click Disk 
Defragmenter.
Your data files are damaged or corrupted.
Refer to your software documentation for file recovery 
procedures. Many software packages automatically create 
backup files.
You may also be able to recover lost data using utility 
software, which is available from your dealer.
Some programs run correctly but others do not.
This is probably a configuration problem. If a program does 
not run properly, refer to its documentation and check that the 
hardware configuration meets its needs.
A diskette will not go into the diskette drive.
You may already have a diskette in the drive. Make sure the 
drive is empty.
You may be inserting the diskette incorrectly. Hold the 
diskette with the hub side facing down, and insert it so that 
the metal head window cover goes into the drive first.
The metal cover or a loose label may be obstructing the path 
into the drive. Carefully inspect the diskette. If the metal 
cover is loose, replace the diskette. If the label is loose, 
replace the label and try inserting the diskette again.

The computer displays the Non-system disk or disk error 
message.
If you are starting the computer from a diskette, the diskette 
in the drive does not have the files necessary to start the 
computer. Replace it with a bootable diskette.
The drive cannot read a diskette.
Try another diskette. If you can access the second diskette, 
the first diskette (not the drive) is probably causing the 
problem. Run Error-checking on the faulty diskette (for 
instructions, see “Disk drive problems” on page 233).
DVD-ROM or DVD-ROM/CD-RW drive problems
You cannot access a disc in the drive.
Make sure the drive tray has closed properly. Press gently 
until it clicks into place.
Open the drive tray and remove the disc. Make sure the drive 
tray is clean. Any dirt or foreign object can interfere with the 
laser beam.
Examine the disc to see whether it is dirty. If necessary, wipe 
it with a clean damp cloth dipped in water or a neutral 
cleaner.
Replace the disc in the tray. Make sure it is lying flat, label 
side up. Press the disc down until it locks on the spindle. 
Close the drive tray carefully, making sure it has shut 
completely.
You press the disc eject button, but the drive tray does 
not slide out.
Make sure the computer is connected to a power source and 
turned on. The DVD-ROM or DVD-ROM/CD-RW drive 
eject mechanism requires power to operate.
To remove a disc without turning on the computer, use a 
narrow object, such as a straightened paper clip, to press the

manual eject button. This button is in the small hole next to 
the disc eject button on the right side of the computer.
Some discs run correctly, but others do not.
If the problem is with an application CD-ROM, refer to the 
software’s documentation and check that the hardware 
configuration meets the program’s needs.
The color of the materials used to make the disc can affect its 
reliability. Silver-colored CD-ROMs are the most reliable, 
followed by gold-colored CD-ROM. Green-colored CD-
ROMs are the least reliable.
WinDVD problems: general issues
WinDVD has been configured to provide optimum 
performance and quality based upon your system’s available 
resources. Changes made to the system or its configuration 
may impact the playback performance of the WinDVD 
player.
WinDVD controls are disabled.
Controls may be grayed out by commands on the DVD disc. 
For example, it is common for DVD movie titles to disable 
fast-forward and rewind during the legal notices at the 
beginning of a movie.
Playback performance is poor.
Make sure your system’s A/C adapter is plugged in and the 
system’s power setting is on full.
The Root or Title menu does not open.
Most DVD titles have one or both of the “Root” and “Title” 
menus. If one menu button appears to do nothing, try the 
other menu button.
WinDVD performance decreases after making a system 
change.
DVD playback performance is dependent upon several 
system resources. Changes to these system resources caused,

for example, by installing a new graphics or audio card may 
impact performance. Some software changes may also 
impact playback performance (for example, downloading 
new drivers from the Web). 
Before installing a new hardware or software component on 
your system, check for any potential conflicts between its 
resource requirements and your current system configuration. 
Also, if you change your operating system, check with your 
PC manufacturer or your graphics card vendor to ensure that 
you have the appropriate drivers for both your hardware (for 
example, the graphics card) and software (drivers must 
support the operating system and DVD with WinDVD).
Slow playback performance.
DVD playback is a resource intensive application. Other 
applications and/or changes to your system hardware, 
software or configuration can impact playback performance. 
If playback is slower than normal, try:
1Closing any other open applications to improve the 
performance of the DVD playback. 
2Ensuring DMA (Direct Memory Access) is turned on.
 See “Secondary IDE Channel DMA setting” on 
page 238.
3If you have installed new hardware (such as a new 
graphics card or audio card), ensure the component’s 
drivers support Microsoft
® DirectX® 8.1 or higher and 
WinDVD. Contact the manufacturer of the component.
4Verifying that your display driver resolution, color depth 
and refresh rate are optimal for DVD playback. (Some 
systems do not support video overlays if these parameters 
are not optimal.) Try lowering these settings to improve 
performance.

from the pull-down menu and click OK.
WinDVD problems: content issues
Movies exhibit poor performance of “Directors 
Commentary” or other similar optional content 
versions.
Some movies may exhibit poor performance of these 
features. In particular, the video portion of the movie may 
become jerky or show pauses. The normal version of the 
movie will not show this problem.
WinDVD will not function properly with “debug” 
software installed.
The WinDVD application will not function properly if it 
detects that debug software is present on the system. Remove 
the debug software to restore functionality of WinDVD.
WinDVD: error messages
This table offers descriptions and resolutions for error 
messages that may appear when using WinDVD.
