Asus P5AD2-E Premium won't start unless...

[fromjim]

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 versin 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

Was the old drive SATA or IDE? Post more specs. Old and new HDD's.

the old one was 500 GB SATA, the new 1TB SATA, only one drive installed at a time.

I forgot to mention the error message is,

Reboot and select proper boot device

Would the problem be that the P5AD2-E Premium can not accept a sata drive with a transfer rate of 6 GBps?

Although I can get to use the drive after much in and out of the bios, I was trying to erase everything on the drive using Acronis tools and can't since it always asks for a re-boot which can't be done without going into the bios, and to do this I have to shut off the external drive which is where I have now placed the drive, I can't even return the drive since it has too much personal and financial info which I can't clean off the drive.

Please give advice if you can.

Thanks
God bless
