CPU: AMD Quad core Phenom II X4920
mobo: MSI 785GTM-E45
HDD: Seagate SATA 1T ST310000520AS
BIOS is set to boot first from SATA DVD reader/writer.
Computer powers up perfectly, shows splash screen, goes into BIOS control with depress of <del> key, etc
However, the installation routine will not start from either of my 64 bit Windows 7 install DVD's. Install routine will start from any 32 bit (Linux, windoze, etc) OS install CD, just not a 64 bit windows install DVD.
Furthermore, I have tried another SATA DVD, as well as a pata DVD reader/writer. Still no cigar
When I attempt to boot into the installation, the spash screen comes up, then goes, and there is a little "hyphen" cursor blinking (ad-infinitum) at the left edge of the screen. Nothing further.
I have used the same install DVD to install Win 7 on another (Intel in this case) new computer once before. It worked perfectly, the DVD has been in its sleeve ever since, and there is almost no possibility that it is damaged.
I am sure that the Phenom II is a 64 bit processor. What is going on here? Do I need to set some system jumper or what?

BTW, this computer is for a non profit and the DVD's were provided under the MS non-profit support program. I also have a pair of XP Pro CD's, one 64 bit, the other 32 (also from the non-profit support program). All have been used to install other computers. None will boot in this system.
I do have a normal XP Pro 32 bit SP3 CD and it will boot, as will all of my recovery disks, linux disks, etc.
I am baffled. There must be some explanation other than the disks being bad. They aren't. It's just that this system will not read them from any of two SATA and one PATA drives. Any theories?
