This problem occurs when the internal battery dies and you loose data for the internal clock and possibly the bios. Refer to this link: http://209.167.114.38/support/Download/files_downloads/PSA60C/SA60EXUM.PDF and go to page 125 in the manual.

The 161 CMOS error means the CMOS/BIOS battery is dead/flat and needs to be replaced.
The 163 CMOS error means the Date and Time could not be updated when you change the Date and Time setting. This is caused by the flat CMOS/BIOS battery.
When you replace the battery with a new one, the BIOS will go back to the default settings, go into to BIOS setting (press F2 when you boot up) and change the Date and Time, then save and exit.

If you have a recovery / restore CD you can do it from it. If not then you have to reinstall the windows as some system files have gone missing / infected with virus. While reinstalling the windows you may get an option to restore to a previous version. If so, then do it otherwise you have to reinstall the windows.

Yes the CMOS battery needs to be changed. Then you can go into the BIOS and set the Date & Time.
The CMOS/BIOS will be set back to the defaults when you remove the CMOS battery and this may fix your problems.
SOURCE: date and time wrong on start up
This indicates the BIOS battery is flat and therefore cannot store the correct date and time in the BIOS. You need to install a new BIOS battery and then go into the BIOS setup to set the Date & Time.
Switch ON the PC, boot the PC in 'Safe Mode'
by continuously tapping F8 button after you switch On.
Let windows boot in Safe Mode and log in to windows.
Go to 'Start'--->Programs--->Accessories--->System Tools--->Click
'System Restore'
A
'System Restore' window will appear.
Here you will have to check "Restore computer to an earlier time' and
click Next
Now you will find one Month Calendar window with Dates below, go to
the previous month by clicking the '<' sign in the upper left hand
corner of the Month Calendar and select any date that you see in Bold.
Note:
It is better if you could remember from which date you are facing the issue,
try to select a date prior to that date.
The
detail of that particular date should show "System Checkpoint" and
time on the right hand side box. Select that date.
Now, Click on Next and System Restore will start and windows will take a
reboot.
After reboot your problem should be resolved.

Hi John young, we want to help you with your question, but we need more information from you. Can you please add details in the comment box?
what operating system is it ?
The operating system is windows 8.1 with bing. The machine is toshiba c50 b 14d bought to replace a very old desktop. I entered the date and time correctly but then switched the machine off when I should have continued following the start up prompts.
