I believe your GRUB configuration is damaged. Boot from a Ubuntu install CD(live CD), and in the terminal on the LiveCD(Use Ctrl+Alt+T), run:
sudo apt-get install boot-repair

When it finishes,(there will be a prompt like ~/test$), run boot-repair and use the automated wizard in boot-repair.

Using USB is the same difference as using a LiveCD. The data for the OS is identical

I also suggest you fsck your partitions and test your RAM using the same live USB.

Set the BIOS to boot the USB first. Your system may have a shortcut to set the boot device for one shot
