Hi, welcome

Without information we cannot say anything, it would be shots in the dark.
Please tell us how much space you reserved for the install, some info about the machine you’re running openSUSE (which version, which desktop environment -KDE / GNOME) on.

I am a new user! PC name: HP 4540s , RAM 4 GB, Hard Disk 500 GB, OS: openSUSE 12.3 (x86_64) GNOME

That is not enough info show us

fdisk -l

note that it is a lowercase L not a one

Did you use BTRFS files system?

The default is normally gives plenty of space unless you gave a very small amount of free space.

Please use code tags (# in editor bar) for computer output so that it does not get reformatted
