Says autosize DRAM, I "think" it means it has lost it's BIOS configuration. The little coin cell battery is dead and it needs to be reconfigured, or "load BIOS defaults" and set the time. To get to the BIOS you tap different keys depending on what computer you have. Most common are "delete", escape, tab or F1 keys but some have other combination. Once in the BIOS just load the defaults and set the time.
