Hi, This may be a bit complicated, but I'll do my best.
I just built a new machine with an Intel MB and CPU. I cloned my Hard disk with winxp sp3 on it to another disk within my old ASUS AMD based MB. Moved the cloned disk into the new machine and I am able to boot into Win XP, but only as far as the LOGON screen. At that screen I hit ENTER to log on and it says "Loading Personal settings" then it goes to a blank blue screen and after a while goes back to the "Logoff" screen. If I hit Cancel it goes back to "LogOn" screen and repeats.
If I try to go in in Safe Mode, I still get the LogOn screen and it does the same thing.
Obviously there is some major hardware issue here, but where to begin to troubleshoot? Any thoughts and ideas welcome.
