Last night, I shutdown my system, and when I tried to boot it this morning it hung at the splash screen.  What is wrong here? I'm not sure which details I can give apart from that I originally installed the OS from bootable USB and Gnome is the desktop environment I am using.During boot, when I enter the GRUB v1.99 screen, the following (editable) text appears:setparams 'Fedora Linux, with Linux 3.1.0-7.fc16.i686 (recovery mode)'load_videoset gfxpayload=keepinsmod gzioinsmod part_gptinsmod ext2set root='(hd0, gpt2)'search --no-floppy --fs-uuid --set=root 9ff50bad-320d-4f07-8a14-4cd372185815echo 'Loading Linux 3.1.0-7.fc16.i686 ...'linux /vmlinuz-3.1.0-7.fc16.i686 root=/dev/mpper/vg_user-lv_root ro single \'rd.lvm.lv=vg_user/lv_root rd.md=0 rd.dm=0 KEYTABLE=us quiet SYSFONT=latarcyrheb-sun16 \`rhgb rd.luks=0 LANG=en_US.UTF-8 rd.lvm.lv=vg_user/lv_swapecho 'Loading initial ramdisk ...'initrd /initramfs-3.1.0-7.fc16.i686.img
