I am sorry to hear you are having problems but let me help you with that.
Based on your description, there are some steps I want you to try as part of the troubleshooting steps:
- The compatibility between the board and the processor will be provided by the board manufacture so I recommend you contacting Gigabyte directly so that they can provide the information.
- Please test a different power supply if possible.
- Another good step is to test a different memory (model and brand).
- Test the system without the video card in the system.
If you are still having problems with the system, you can run the processor diagnostic tool to diagnose the internal components of the processor. Here is the link:
If the result is good, my recommendation is to contact the computer manufacture for a future replacement if necessary.
