BSOD while Shutting Down the Windows

I have recently bought a Kingston DDR2 2GB KVR800D2N6/2G and installed Windows 7 Ultimate x64.
It has been happening recently that when I shut down the computer, my PC goes BSOD.
Please help me in diagnosing this problem. Thank you.

Seems like bad RAM

Thanks for the quick response.
Will report back as soon as I have checked the RAM.

OK, so I have checked the RAM as advised. No errors were found by Memtest86+

Reset your BIOS settings to their Default values/Auto, is your RAM compatible with your board?

The BIOS settings are set to default. And my board supports the RAM. On a side note, I would like to add that my BIOS is NOT updated to the latest version.
