SolutionCause
Be sure that all cables are properly and securely connected and that pins in
the cable or connector are not bent down.
Cables of new external device are loose or power
cables are unplugged.
Turn o the computer, turn on the external device, and then turn on the

Power switch of new external device is not
turned on.
Reboot the computer and follow the instructions for accepting the changes.When the system advised you of changes to the
conguration, you did not accept them.
Use Windows Device Manager to clear the automatic settings for the board,
and choose a basic conguration that does not cause a resource conict. You
can also use Computer Setup to recongure or disable devices to resolve the
resource conict.
To access Device Manager in Windows 10, type device manager in
the taskbar search box, and then select Device Manager
from the list of
applications.
A plug and play board might not automatically
congure
when added if the default
conguration conicts with other devices.

SolutionCause
1. Review the documentation that came with the system to determine if
y
ou are using the correct memory modules and to verify the proper

ins
talled before DIMM3.
2. Observe the beeps and lights on the front of the computer. Beeps and
blinking ligh
ts are codes for specic problems.
3. If you still cannot resolve the issue, contact Customer Support.
Wrong memory modules were used in the
upgr
ade, or memory modules were installed in
the wrong location.
Power light blinks red three times and then white two times

unpl
ug the computer power cord before attempting to reseat, install, or
remove a DIMM module.
1. Reseat DIMMs. Turn on the system.
2. Replace DIMMs one at a time to isolate the faulty module.
NOTE: DIMM1 or XMM1 must always be installed. DIMM1 must be
ins
talled before DIMM3.
3. Replace third-party memory with HP memory.
4. Replace the system board.
Memory is installed incorrectly or is bad.
