Over Clock or Voltage Change Error

Over a year ago I built a computer with all setting to default (no over clock, no nothing). This machine run well until last friday. On friday, during a re-boot I got a message stating that the BootMgr was missing. Upon further inspection within the Bios, it was noted that I had an Over Clock or Voltage Change error. I also notice that my second hard drive (data storage only) was now my primary boot up drive (no wonder it could find the BootMrg). So, I reset everything and restarted with no further problems. About 4 hours later the computer locked up. Upon inspection of the Bios, that same Over Clock or Voltage Change error was found again. So, I reset everything again. I have now had to this 7 times. I do not understand what happening!! Is it possible that I have a piece of hardware failing? Any thought are greatly appreciated.

Computer specs: i7-2700K processor; Gigabyte Z68A-D3H-B3 mother board; 16GB of SDRAM Patriot Viper Extreme Series Division 4 Edition; 120GB OCZ Vertex 3 Max SSD primary HD (OS location) and a WD 1 TB Caviar Blue secondary HD (data storage only)

  1. Hmmm sounds like your bios is messed up. Try to reflash it.
  2. Probably a hard glitch.

    I took your advice and flashed the Bios with a newer Bios software version. This has definately reduced the frequency of my "Over Clock or Voltage Change" error, but not eliminated it completely. I have noticed something else that was probably present during the other failures. I have noticed that upon restart (after an error) that my RAM speed has been reduced (automatically) from 2133Hz to 1333Hz and my SSD is sometimes removed from my boot list. When I completely shut the computer down and restart it returns as the 2nd boot drive or sometimes the 1st boot drive.

    I'm beginning to wonder if my mother board, my RAM or my SSD have some sort of intermittant problem. Any thought?

    Well from the sound of it your Motherboard's CMOS chip is damaged, so could you try it with another motherboard maybe?
