Hello HP community

I am having problems with a ProDesk 400G7 Small Factor S/N: [personal info removed] computer, which presents the following:

"The red light blinks five times, and then the white light briefly blinks four more times (5 long red blinks and 4 short white blinks)."

I have already performed a reset of the Board (CMOS) but the problem persists. I have even changed the power supply.

I would appreciate it if you could please help me find the root cause of the event on the computer.

I look forward to your comments.

Thank you very much.
