Dh61ww & i5 2400 drivers causing issues

Hello,

I have assembled a pc recently by myself. The configuration is as follows: -

Intel i5 2400
motherboard - intel DH61WW
500 gb sata seagate hard disk

I tried to install the drivers from original CD, after installation screen come up with full of dark blue lines all over the screen and I can't see anything. Then it automatically get restarted. It prompted to choose mode.

Then I restored OS back to initil state. Later I downloaded the new drivers from intel, now its fine but I have one issue

1) When I click shutdown, its getting restarted after 10 seconds or so.
meanwhile cooling fan is running, keyboard led is on..

Please suggest me some solution. Thanks in advance.
