I have had a Crucial M4 256 GB SSD running in my system for about a year and I recently got a BSOD and had to restart my computer. Now when I restart the OS won't boot unless I hit a key, usually F2 or Escape fairly soon after the machine Posts. If I don't do this it won't boot to Windows. Other than that everything seems to work just fine after it boots up. Is there some setting that got reset that would cause this?
