Memory count during POST is wrong.
Cause
Solution
The memory modules may not be installed correctly.
Check that the memory modules have been installed correctly
and that proper modules are used.
Integrated graphics may use system memory.
No action required.
Insufficient memory error during operation.
Cause
Solution
Too many Terminate and Stay Resident programs (TSRs) are
installed.
Delete any TSRs that you do not need.
You have run out of memory for the application.
Check the memory requirements for the application or add
more memory to the computer.
Power LED flashes Red five times, once every second, followed by a two second pause, and the
computer beeps five times. (Beeps stop after fifth iteration but LEDs continue flashing.)
Cause
Solution
Memory is installed incorrectly or is bad.
1.
Reseat DIMMs. Power on the system.
2.
Replace DIMMs one at a time to isolate the faulty
module.
3.
Replace third-party memory with HP memory.
4.
Replace the system board.
Solving Processor Problems
If you encounter processor problems, common causes and solutions are listed in the following table.
Table 8-13
Solving Processor Problems
Poor performance is experienced.
Cause
Solution
Processor is hot.
1.
Make sure the airflow to the computer is not blocked.
2.
Make sure the fans are connected and working properly
(some fans only operate when needed).
3.
Make sure the processor heat sink is installed properly.
