12.04 Slow response, lost bookmarks

Have you tested your RAM using Memtest86 from GRUB?
You could also boot to Live CD desktop and do a full fsck of the file system.

  You'd have to walk me through that so I don't goof up. Also, I don't know what you mean by " boot to Live CD desktop."

  It came up with " /dev//loop0 contains a file system with errors, check forced.' How do I correct that?

Are you using Wubi?

Yes.

Wubi hasn't been developed for over 4 years and is dead.

All I can suggest is that is check the health of your NTFS partition which is holding the disk image used in Wubi.

Wubi is not supposed to be used for long stretches of time and cannot be upgraded to the next release or LTS release. It's a quick and dirty try-before-you-buy solution before you commit to a real install.

I recommend you uninstall Wubi, resize your NTFS to make free space then boot to an Ubuntu installation media (ideally Xenial, Ubuntu 16.04) and setup a dual boot.
