Try the following troubleshooting steps
1. As the first troubleshooting step, we recommend you to clear the CMOS. To do this, please remove power to the motherboard, all cables and the RTC (Real Time Clock) battery for 45 minutes. After this period of time, insert the battery back in and turn the system back on.
2.Try booting the system with just the memory and processor installed. Bear in mind that if you do not install the memory on the motherboard, you should hear three error beeps. This means that the processor and the motherboard are indeed communicating.
If there were no beeps, the next step would be to test your system outside of the chassis. Place your motherboard on a table, on a non-conductive material, and try booting it with only basic hardware attached. This step is to ensure there are no grounding issues with the system case.
3. If this fails as well, please test all the components in a different system and make sure that every part is working fine. The most important parts to test are the processor, the motherboard and the system memory. (Please write down the model of the testing hardware).
4.On a non-booting system, the only way to determine the failing part (processor or motherboard) is by testing them both on separate systems.
