Recommended Action
1. Check that the voltage selector,
located on the rear of the power
supply, is set to the appropriate
voltage. Proper voltage setting
depends on your region.
2. Open the hood and ensure the
4-wire power supply cable is
seated into the connector on the
system board.
3. Check if a device is causing the
problem by removing ALL attached
devices (such as hard, diskette, or
optical drives, and expansion
cards). Power on the system. If the
system enters the POST, then power
off and replace one device at a
time and repeat this procedure until
failure occurs. Replace the device
that is causing the failure. Continue
adding devices one at a time to
ensure all devices are functioning
properly.
4. Replace the power supply.
5. Replace the system board.
1. Reseat DIMMs. Power on the
system.
2. Replace DIMMs one at a time to
isolate the faulty module.

HP memory.
