I've recently encountered the following error message:

I run sudo fsck /dev/sda2 which is the Ubuntu ext4 root partition via LiveCD. It checked and fixed the file system. The next time I boot, Ubuntu started to load with the Ubuntu logo and the dots underneath for several hours (with the mouse pointer active on the screen), I even let the computer on overnight but still it did not successfully boot or got to the login screen in the morning.

I booted again with the LiveCD and checked the NTFS partitions with ntfsfix and again the NTFS partitions was checked and fixed successfully. I also edited my fstab and commented out the lines that auto-mounts the NTFS partitions. The next time I boot, it took almost 20 minutes for Ubuntu to get to the login screen, after typing the password it took an additional 10 minutes for Ubuntu to get to the desktop. On the desktop, it take several minutes to open any program, displaying the Dash alone takes 5 minutes!

Is there a fix for this without having to reinstall Ubuntu? I don't see or get any errors, Ubuntu is just taking too long to boot and to run programs. Please help!
