|Thank you for the reply.|
None of the above, Windows Vista Ult., Norton 2010 and System Mechanic were new installs. All have been on my system for three years with no problems.
The fan on high speed seems to indicate the CPU is overheating.
I thought of that causing the problem and maybe killing the cpu, But I thought by me changing the mother board would make the startup different on my first try?
Remember, the only thing that happens from inital startup is high speed fan, all else looks to be powered but I can do nothing else ie go to bios, safemode or use a boot disk.
Thanks again, and hoping for more info
On the Norton, I left it many many years ago vowing never to return, but it came preinstalled on my system, It seems to do what I need it to do fast and I have not had one problem unlike the past. hence it is still on my dead system and this old XP computer
