I have pretty much the same deal same board with I7 Sandy. 32 gig memory. I have a SSD (sandisk) as well. I loaded windows 7 (Pro 64 bit), I was succesful once getting into the bios when the screen came up, it would flash and then go to the OS. I was able to hit F12 quick enough while the bios screen was still up. But I'm thinking that it should stay until I exit the bios since I held down the delete key per the instructions, but no. I'm wondering if I am able to get back into the bios and flash it if that would help (also have version f4). It's hard to hit a moving target.
