Change pos. of cards

Hello
Thanks for taking the time to read this post.
I have an S5 with a 928b and a cp581(486 cpu),cp581 is running win95 with coros ls-b oper. interface program, but when we power up and after win 95 loads coros freezes at main logo,we have reloaded backup
program of coros, but did not work. I was told that it mite be the backplane of the rack, so could i move the cards to another slot or will there be an address problem.
