If you're getting blue screens while trying to install windows you have a hardware issue. If the drives are old it could be that your hard drives are on their last breath. Also, are these SATA or IDE drives?...I've had problems in the past with a dying drive causing my system to BSOD constantly....One of my IDE drives were dying and it would cause the system to bsod. As soon as I removed it the system became stable. I'm not sure how this would effect SATA drives since they have their own direct connection and don't share a cable if you have multiple drives.....
But try to have only one drive installed....see if that works...Also run memtest to check for memory errors. Reply once you test those out for alternate suggestions if they aren't the case.
