Hi Everyone, Not quite sure where to post this problem of mine but this looked like a good place. I purchased a Dell Dimension 2400 in Nov. 2005, couple of weeks ago (after bad storm) it would not turn on.I finally decided to take it in for repairs, well the motherboard was fried along with a few other things. They had a good Gateway motherboard so they combined the two, took what was good on mine and put it into the Gateway. Hard drive works, I turn on the computer it loads all the way to our names but when you click on a name the activate windows comes up. I called Micro Soft and they say I am running a illegal copy because I purchased this from Dell and it needs to run on a dell motherboard. I cannot get into setup anything not even the internet. As of now I am not sure what is in my computer but I am running Windows XP Home Edition on a Dell Hard drive with Gateway motherboard. I also have product key but Ms would not take it. Can someone help please?
