Firstly, after reading your post very carefully I think you have followed the following sequence
Start>>>Turn off computer>>Turn off
To shutdown normally
, and then the computer will not restart, then hardware is the cause.(
If you have followed Start>>Turn off computer>>restart, and the computer fails to restart, then the problem is with Windows and you may safely ignore my entire post.)
1. Please supply the information requested in earlier posts.
2. Is there any indication of activity in the conputer ( as per Mr Optomistic), or
Power on light or
harddrive activity light
.
There is insufficient information yet to make a definite diagnosis, but so far my money is on correct operation of strategically placed temperature sensors within the computer. When the targeted fans in the computer shut down there will be a temporary increase in temperature in the monitored components probably preventing the computer from restarting until they have cooled naturally. In other words, I think your computer may be telling you that it's protection circuits are functioning perfectly.Good luck.
