I would recommend that you read some of the many "FX-9590 Freezing" threads here which show all of the typical issues that cause the FX-9590 or any 8-core FX processor to freeze. A systematic diagnostic approach using the applet OCCT will allow you to record CPU functions, temp, etc. to see what is happening just before the system freezes. You also might want to run Memtest86+ V5 or later overnight to see if there are RAM issues. You may even need to use only one DIMM to see if the problem is RAM related.
