Windows restart power down error message

[li0nhart79]

On my parents' computer that I have build them, there has recently been an odd error message when rebooting. For a few months now, no matter how you reboot the computer, before windows loads, there is an error message from the BIOS that the computer was not powered off correctly. It then gives two options to select. One is to go to setup and the other is load default settings.
The computer is pretty old by computer standards. Pretty much all I do is whenever I upgrade my PC, I transfer whatever I updated into theirs. They don't use it for much besides internet so it's still an upgrade for them.
My thought is that it's something with the power supply. I have a tester and the voltage tests out OK. I am not too worried about the cost of a PSU, but before I buy one I figured I would see if anyone on here has any suggestions. I realize it could be other issues as well.
Thanks

If your PSU voltage output is normal, try to set it in default settings, and check your bios battery if it have a 3 volts DC using VOM or tester. Then go back it here and report me what is the changes.

I checked the battery and it read 3.29 on the meter which is normal. However, when I powered it back on I noticed more of the message I for some reason has missed before. It actually says that surges with the power supply were detected on the previous power down and that's why my Mobo was alerting me. I guess that answers my question about the power supply lol

Thanks for your feedback! While it did not solve the problem directly. your help got me there still.
