My COMPUTER will only start if I first enter the bios, I have tried using the default settings, upgraded all my drivers, I hate to change the motherboard without being sure.

In my effort to solve the problem I replaced the hard drive which I had cloned from the OLD drive, after many attempts I got it to work but each time I shut it down for the night the next day it would not start until I went into the bios , did really nothing, and then it would start.  I changed the Bios battery, updated and flashed the Bios with the latest version 1006.006 but my problem still EXISTS.  I did all the SCANS Seatools for Seagate Barracuda can do and the drive passed all tests. 

Ideas please, I suspect problems with my motherboard but want to try all first.

Thanks
God bless
FromjimI forgot to mention, the error message is,  Reboot and select proper boot device

Thanks
God bless
JimDoes anyone know if the problem could be that the new drive is a 6GBps and the old one was only 150 MBps, both are sata DRIVES, Those are both pretty small drives/partitions...Post a screenshot of Disk Management and fully describe what you have done in the BIOS...
