I just upgraded my PC, moving from an Intel processor to an AMD Phenom II on a Biostar TA790GXB A2+ board. My old pc recognized my SIL0680 RAID card and my 2 striped arrays worked fine. I built my new pc and installed the RAID card with no issues on Windows XP Home SP2. When I put the drives in, the RAID BIOS recognizes both arrays, the mobo BIOS recognizes both arrays, but Windows hangs. The POST screen runs as usual, the SIL0680 screen appears and finds the arrays, then the hardware monitor screen opens and shows everything normal on the board, then I get the 'beep' that indicates the hardware is done and Windows is starting. Then nothing...the hardware screen is still there, but Windows never starts. When I remove the drives (disconnect the IDE cables at the SIL0680 RAID card), system boots fine. This is a major issue for me, as I have a couple's wedding photos on my RAID drive (one is the main array, the other is my backup) and I can't get them off of the drives. Windows shows no conflicts. Mobo shows no issues. What could be the problem? I can't generate any kind of 'log' since Windows never starts. Any ideas? Thanks!
