This issue could be related to a lack of power from the power supply. Testing a larger power supply would be a good place to begin troubleshooting. Also, check the system memory specifications. Bear in mind that RAM with voltages higher than 1.5V, might not be fully compatible with your processor.
It may be because you are on a 32 bit operating system instead of 64. I just ordered this board and it is capable of something like 16 gb memory or something like that but doesn't matter because it can only be recognized by 64 bit os. Anything beyond 4 gb on 32 bit is redundant.
