My problem is that I have just build this new i5 rig, but eveytime i restart it, it will turn on for 9 seconds and then switch off, before turning on again for another 9 seconds. It will repeat this three times and then boot up perfectly normal.
I have not overclocked anything, or tried anyway. Reformatted windows, same problem.
If you have any more trouble look in device manager for the old mb drivers .
Depends how you did the swap but there could be a whole bunch of entries with yellow triangles next to them . Just right click and remove them and that will be uninstalling the drivers .
That should tidy things up a bit and windows wont get so confused
