Boot Camp on Snow Leopard can't install Windows-Stuck on black BIOS screen

I'm running Snow Leopard 10.6.8 on an early 2008 Mac Pro (dual 3.2Ghz Harperton CPU's, 10gb RAM) with Boot Camp version 3.0.4 (all updated). I've successfully had a Boot Camp partition in the past, running WindowsXP32 Bit. I just purchased Windows7 Professional and can't install either the 32bit or 64 bit version. Neither can I install any of my original Windows disc. Boot Camp successfully creates the partion, then asks me to install the Windows install DVD/CD which I do, and then when it reboots, it gets stuck in a black BIOS screen that says "Initializing..."

I've tried all my Windows discs: WindowsXP-32bit, Vista-32Bit, Vista-64Bit, Windows7-32Bit, Windows7-64Bit. Same problem...gets hung on the black BIOS screen. I disconnected all my USB hardware except for my keyboard/mouse. All my other internal drives are disconnected.

The only thing that I can think of is that is different is my MacHD is a 500GB Seagate MomentusXT solid state hybrid drive.

Any help is greatly appreciated!!!!!!!

Thanks
