Hi I recently built a new system using the Intel DX79SI motherboard and the i7-3930k processor. with no applications running except for explorer opened to a share on another local network system and a command prompt window, the system eventually goes to sleep as expected, however if I click my mouse, press a key on the keyboard the system is unresponsive. The power LED just flashes continuously. The Post Code LED's read "03". If I press my power button again no response, my monitor remains dark, the power LED on my case just flashes and no hard drive activity is apparent.
If I hold the power button down until the system powers off and then restart the system when windows starts it says "Resuming Windows". The system does come back to the exact state it was in before sleep (explorer opened to a network share and a command prompt window with previous data still visible). However even after the system is back and has been back for many minutes the Post Code LED's read "30". The system seems normal and responsive otherwise. A subsequent restart loads as normal and once the OS is up the Post Code LED's read "00" as expected.
Below are my system specs any guidance is appreciated.
