Its the same issue i reported months ago. tried increasing imc + vtt 0.005 like you said seemed to work.. Then just randomly sometimes it dont start 1st time...system auto off's 4 times then starts like nothin happen
It';s most likely a peripheral,
Unplug everything but your mouse and keyboard. Boot into BIOS, load optimum defaults. If you are RAID make sure to back and change it from AHCI to RAID because optimum defaults don't save that.
Save and exit. Run shut down and see how she does on a clod boot. If it still does it RMA that puppy. If it boots clean do it a few to make sure and then add one peripheral at a time until you find the issue.
i know two cases of eSATA screwing up cold boots.
