    I'd say Power Supply or Ram

    You need to swap parts in and out, until you work out which one is faulty.

    Actually this is a good start: BenchTesting

    first check is to test the PSU with a tester tool and multi-meter.

    No, the "PowerSupplyUnit" (PSU) inside the Desktop computer

    this is an old computer where the power supply to the monitor comes from the psu in the desktop...

    The monitor does not use the entire PowerSupply (circuitry)

    power to the monitor and/or the mobo does not guarantee you are getting sufficient power or correct voltage off the PSU. The only way to be sure is to test it with proper tools. Most monitors do not run off of PSU power. In fact, I know of none, but there could be some out there.
