Help with \windows\system32\config\system and get data back

Hello,
Im having problems with an old computer that i set up a few years back and would like to get some data off of it. The computer set up is 2x 80GB set up in a RAID 0 (stripped) to be one 160 which house some data and my OS. I also have 2 other hard drives which i also have a RAID 0 which houses just data. So there are two different raid set ups. The computer was originally set up using Windows XP pro.

When i try and start the computer i get the following error:

Windows could not start because the following file is missing or corrupt:
\windows\system32\config\system

The motherboard is a DFI landparty NF4 I set it up several years ago. When i set it up a clicked f10 and stripped the drives. When installing windows i clicked f6 to install 3rd party raid drivers from DFI.

When the computer boots up it says that the drives are striped and that they are healthy and it shows me 167GB. If i click f10 and go into the raid setup it shows that the raid is set up and healthy.

I tried going into Recovery Console but i keep getting errors.
Either The command is not recognized or Access is denied.

I also tried hooking up the hard drives to another computer to just pull the data off of them. This was however a windows 7 machine. It will pick up that there is a hard drive in my computer but when i go to click on it, it asks me to format the hard drive. If i right mouse click and go to properties, it doesnt have any info on the drives.

Im more concerned with the info thats on the 2 500s. Is there anything i can do to get the info off the hard drives. Someone had told me to reset up the raid but i dont have an option when i boot up into the bios and click f10. Do i need to reinstall the 3rd party raid drivers when windows is starting and then go into recovery console?

Thanks
