About Your System
Causes
The processor cooling fan is faulty or
the fan assembly is not installed
correctly.
The system encountered a problem
while trying to configure a PCIe
expansion card.
The OS Install Mode option in the
System Setup program is set to On.
This limits the amount of available
memory to 256 MB because some
operating systems will not complete
installation with more than 2 GB of
system memory.
The fan caused errors the last time the
system was used.
The system failed to complete the
boot routine three consecutive times
for the same error.
The processor overheated the last
time the system was used.
Corrective Actions
Ensure that the processor cooling shroud
is properly installed. See
"Troubleshooting System Cooling
Problems" on page 86 and
"Microprocessor" on page 62.
See "Troubleshooting Expansion Cards"
on page 93.
Use only Dell supported processors. See
the Getting Started Guide for a list of
supported processors.
After the operating system is installed,
enter the System Setup program and set
the OS Install Mode option to Off. See
"Using the System Setup Program" on
page 27.
Ensure that nothing is blocking the
airflow vents and that all fans are
properly installed and operating
correctly. See "Troubleshooting System
Cooling Problems" on page 86.
See "Getting Help" on page 107.
Ensure that nothing is blocking the
