sorry about the confusion. The old machine is working fine. The problem is with the PC that has POS installed. I have backups of the pc that includes the POS, the problem is the pc keeps having problems after I have restored them. It will work fine for couple of month and there will be problems. Its happend more than 4 times already in the past year.
I was thinking maybe there is something wrong with the pc it self so I was thinking of replacing it with new pc and use my backup to restored it to a new pc.
I hope this is more clear than what I was replying before.
