===Check memory (RAM)===
Verify RAM modules are installed. The system will not boot without it.
===Check storage (HDD/SSD):===
Verify power up without storage. Sometimes damaged drives may cause the overall system to malfunction.
===Check power supply (PSU):===
* Verify the power supply is not damaged and functions properly.
*If you have another power supply use it to eliminate and determine the failing side.
*In case you use other power supply make sure it provides uninterrupted power and stable grounding.
