This could be caused by the power supply subsystem or system components. As a result, proceed as follows:

1. Verify all power cables and adapters are connected properly [AC (electrical outlet power) cables as well as the cables between the power supply unit (PSU) and system components].
2. Cross-test the PSU, if possible.
