I am on the way to replace my existing M/B with a newly purchased one (both are the same socket). I post this question a couple of weeks ago but have not receive anything. During this period of time, I have gone out for a long business trip following a holiday with family and kids, so that I still have had no chance to touch the desktop. I still need advice of resplce the M/B and I am trying my luck again. I resemble the Pt4 PC myself but not sure if the replacement of M/B is as simple as plug-out everything of the old and plug-in everything to the new. I am going to back up my files for sure. But what about other thinks such as BIOS etc those come with the old M/B...Anything you think you would advice me would be highly appreciated. Regards!
