If a device is either not detected during 

the operating system setup or is detected 

but incorrectly configured, you can use the 
Hardware Troubleshooter to resolve the 

incompatibility.
To start the Hardware Troubleshooter:

Click 

Start 

 

→ Help and Support.

Type 

hardware troubleshooter in 

the search field and press <Enter> to start 

the search.
In the search results, select the option that 

best describes the problem and follow the 

remaining troubleshooting steps.

If you experience a problem with your 

computer, perform the checks in “Lockups and 

Software Problems” on page 49 and run the 

Dell Diagnostics before you contact Dell for 

technical assistance. It is recommended that 

you print these procedures before you begin.

NOTE: Dell Diagnostics works only on Dell 

computers.
NOTE: The 

Drivers and Utilities

 disc 

is optional and may not ship with your 

computer.

Ensure that the device that you want to test 

displays in the system setup program and is 

active. Press <F2> during POST (Power On Self 

Test) to enter the System Setup (BIOS) utility.
Start the Dell Diagnostics from your hard drive 

or from the
