Check Administrative Tools > Event Viewer and see if there are any items listed that could be causing the problem.

I already Checked.

it is not displaying any error or warning in event viewer.

Is the (NumLock) LED still ON (and responding to changes) on the keyboard ?

Is the (green) light stil ON on the monitor ?

Can you see any HDD activity going on when the screen goes black ?

Does this happen while you're working or could it be some power saving feature gone bad ?

If you press the power button once (when it happens), does the computer shutdown ?

Can you try leaving it on BIOS screen for 2 hours, that would rule out software problem.

Navigate to the "Start" menu and right-click on the "Computer" link on the right-hand side. Select "Manage" from the pop-up menu. After a few seconds, the Computer Management dialog will appear.

Navigate to the left side of the dialog and expand the "Task Scheduler" folder. Next, expand the "Task Scheduler Library," "Microsoft" and "Windows" folder.

Click on the "Mobile PC" folder. Right-click on the "TMM" listing and click "End." Right-click again and click "Disable." Doing this will stop TMM from starting, which will prevent the black screen from appearing at startup.
