You can review the BIOS settings here: http://www.intel.com/support/motherboards/desktop/sb/CS-020304.htm Desktop Boards — BIOS Settings Glossary

Did you try connecting the optical drive to a different black SATA port?

Hi Joe,

Thanks for your reply..

I guess issue is with Ram.I have removed 4 GB ram which is having speed of 1600Mhz installed in channel b dimm1 .After removing ram I am able to install windows 7 64 bit operating system .currently there is only one ram which is 2 gb with speed 1333mhz in channel a dimm 0.

could you please update me whether this mother board supports 4 gb ram with 1600mhz speed.Please provide me the document which contains proper way to place ram in motherboard.
