Windows 7 - SATAII PCI Controller Card, Can't Boot Windows

I got a PCI SATA Controller card for X-Mas though so it makes up for the temporary loss of 2 SATA ports. The card is marketed as SYBY,sold as I/O Crest brand, but bottom line is it is using a SIL3124 chipset. When I install the drivers from the SIL website, or even SYBA website, and get them installed, it screws up my windows boot record beyond repair. I have 3 HDDs attached to the SLI controller(1 TB WD Black & 2x2TB Black/Green all are SATA II drives) but on the mobo chipset(MSI P67A-G45) I have 2xIntel X25M in RAID0 plus one 2TB Black SATA III. I do not want the 3 drives on the SIL controller to be JBOD. Can any one tell me which drivers and BIOS I need for the SIL card.

I have experience with this card. I can tell you that installing drivers for it can not possibly affect your boot system if you changed nothing in your BIOS. The drivers get placed in Windows\System32\Drivers. So, let's help you start over with it.

With the pc down and open, remove the 3 sata drives attached & remove the card.

What were you booting with before? The mobo raid? Is that where your Windows 7 is? What was the boot order in your BIOS before you installed the Silicon Image card?

If you haven't changed anything in there, removal of the 3124 should allow you to boot.

Trying to run six hard drives on top of the stock hardware will require one hell of a power supply. That HX520 in real life is not giving you the 520 watts. Probably 485. My guess is you don't have enough power to run six hd's and a Sapphire graphics card.

And, it feels as if you'd like to set up two raids? Why?
Please answer those few questions and THINK VERY STRONGLY ABOUT DOUBLING YOUR WATTAGE.
