I would start troubleshooting the problem by running memtest from the Ubuntu CD.
Also, whilst on the LiveCD please post the results of the bootscript linked at the bottom of my post.
Thanks.
Thanks for reply.
I already went ahead and installed just Ubuntu.
Sorry, I wasn't given memtest option when about to boot from live USB flash drive.
