1) Check for power supply low voltage or overload. Make sure the PSU meets the minimum wattage requirements for that CPU / Mainboard combination. Make sure testing power supply meets HP specs, if the system utilizes a proprietary extra connector, your testing PSU may need to be the same HP part number. 2) Check signal cable on monitor for intermittent connection or swap monitor. Check brightness/constrast adjustments; monitor may also have a setting for input voltage: check! 3) Swap VGA card if applicable. 4) Check for grouding on systemboard. If there is an incorrect ground or short it may cause voltage loss across the VGA output.
