If these are Windows PCs, use Netbeui through Network Neighborhood if you can...it'll run better than TCP/IP. If you don't have an IRQ conflict, you may have either a memory problem or a processor/mobo problem. Those are the most common probs for CPU reboots. If you are running into this problem and you REALLY need to move the data, look for a Win95 Direct Connect Cable. It runs on your 25 pin female connector(DB25) printer port. You can hook that up and load your Direct Connection software that comes with windows and it should work, but it may do the same thing if your problem is hardware... Either way, the only way to solve it is to test it and try swapping things out... Good luck-
