Do these indicators light up within seconds after the boot routine starts?

Yes.  Go to step 4.

No.  Troubleshoot the power subsystem.

4. While the boot routine is running, observe the computer for any of the 

following:

Diskette-drive and hard-disk drive access indicator activity

These indicators light in response to data being transferred to or from the 
drives. If either of these indicators fails to light during the boot routine, 
troubleshoot the diskette drive or hard-disk drive subsystem, as 
appropriate.

System error messages

These messages can indicate problems or provide status information. If a 
system error message is displayed, refer to Table 3-2. 

Beep codes

A beep code is a series of beeps that indicates an error condition. If the 
computer emits a beep code, refer to Table 3-1.

Any unusual sounds

5. Observe the display for the Diagnostics Menu of the Dell Diagnostics.

Does the Diagnostics Menu appear on the display?

Yes.  See “Running the Dell Diagnostics” in Chapter 3.

No.  Go to step 6.

6. Insert another copy of the diagnostics diskette into the diskette drive, and 

reboot the computer.

Does the Diagnostics Menu appear on the display?

Yes.  See “Running the Dell Diagnostics” in Chapter 3.

No.  Go to the next section, “Eliminating Resource Conflicts.”

Devices within or connected to the computer may require dedicated memory 
spaces, interrupt levels, and/or DMA channels. Because different devices can be 
configured at different times, it is possible that the same resource is assigned to 
two or more devices.

Disconnect all peripherals and remove all PC Cards to make sure that the com-
puter failure is not caused by faulty devices.
