Basic Troubleshooting
This chapter guides you through some initial checks and procedures that can solve
basic computer problems. It can also direct you to the appropriate chapter in this
guide for detailed troubleshooting information and procedures to solve more complex
problems. You should complete the checks in this chapter before calling Dell for tech-
nical assistance; even if these checks do not provide an immediate solution, they can
help support technicians diagnose and fix the problem.
NOTE: If your computer is wet or damaged, see "If Your Computer Gets Wet" or "If
Your Computer Is Damaged" in Chapter 5.
Backing Up Data Files
You can lose data when a system failure occurs. If your system is behaving erratically,
back up your data files immediately.
You do not need to back up Dell-installed driver files for Dell-installed devices. The
driver files are preserved on the Dell Dimension ResourceCD.
NOTE: In case of warranty replacement of your hard-disk drive, you will receive a
blank formatted drive from Dell. You must reinstall application programs and restore
data files.
Installing Additional Hardware and
Software
If the problem you are experiencing began after you made a change to your computer,
such as installing new hardware or software, undo the change if possible.
If the problem is resolved, check any documentation that came with the hardware or
software you attempted to install or that describes the change you made. In particular,
read any text files (such as readme.txt) included with the software package or hard-
ware product; such files contain information updating or supplementing the
documentation for the software or hardware. Typically, readme files provide installa-
tion information, describe new product enhancements or corrections that have not
yet been documented, and list known problems.
