1) install the pci raid card and hook up the old hard drives
2) Set that as the primary boot, boot up to that windows partition, then install the new raid controller for my mobo onto it, and then shutdown.
3) Hookup the new drives to the mobo raid controller, restart, go into the mobo RAID BIOS, and set up a new raid array (maybe RAID-0 instead).
4) Boot to the Partition Magic disk utility from the floppy, then use it to copy the partition on the old drives to the new drives.
5) Restart, and switch the boot order to the new drives and be able to boot into Windows
6) Wipe the old drives and just use them for general multimedia storage, and I guess I could plug them from the pci raid card into the mobo IDE instead and get rid of the pci card.
Do you think this would work??
It may work. Like pscowboy said, there is a lot of hardware change associated with the new motherboard. However, I think it will boot, since initially you'll be using the PCI RAID card that it's currently booting from.
If it initially boots up and lets you get into Windows, you should be able to go from there and make all the necesary changes. Once it boots up on the new motherboard with the old PCI RAID card and drivers, I would go ahead and perform your steps above, copying your installation to the new drives and new motherboard controller before you do any other driver installations. This way, you have a copy of your partition on the new drives as early as possible in the procedure. That way if anything goes wrong later, you can go back to your old system, old PCI RAID card, and the only thing done to the original installation is that the new motherboard RAID driver was installed.
Once you're up and running on the new drives on the motherboard RAID controller, then you can install drivers for the new video card, sound card, network, chipset drivers, etc. If you had old drivers that offer an uninstall (NVidia & ATI video drivers typically offer an uninstall in Add/Remove Programs, a lot of sound cards do as well), then uninstall them before trying to install the drivers for the new hardware.
I would also then clean up device manager by doing the following:
1. Open a command prompt on the system, and type:
devmgr_show_nonpresent_devices=1
and hit enter. Close the command prompt.
2. Open device manager. Go to the View menu, select "Display Hidden Devices".
3. Now, all devices that this installation of Windows has ever seen will be shown. Go through each category, find any greyed-out device that is no longer installed in the computer, right-click it, and select "Uninstall".
One exception: Do not remove any device under the "Non-Plug and Play Drivers". Leave that category alone.
After that, your system will be cleanly running on the new motherboard.
