[SOLVED] So I know this is the wrong place, but for those that had the issue as well, I found the fix that worked for me. I went back into my settings and even though Undetermined was selected in my languages preference, I clicked the big “X” to the right of the list, and saved. Now all the posts show up. thanks especially to @Deez@lemm.ee for all your suggestions.
Could be a dead CMOS battery, but if the computer had a case switch more likely it was a security feature that lets you know the case was opened. On Acer computers you would have to press F1 to continue the boot, or Del key to enter the BIOS and have the chance to change the setting. Incidentally the setting is usually under the Security tab> Open Chassis. You can reset the notification or turn it off.
I run into this situation on office computers all the time, because no one knows how to turn it off or reset it.
