Computer restarts every time I boot up and POST, resets FSB

[Hammyton]

I have a e7200 that was OC'd to 3.0ghz, running fine for about a year. Just starting a few days ago every time my computer boots it up it restarts after POST, and the FSB etc gets reset to "safe" settings (stock 266mhz FSB), and then boots normally. When I go into the BIOS CPU settings it pop up a red screen that says voltage/fsb were reset to stock due to a crash occuring. At first I figured it was an OC'ing issue but if I manually go in and change FSB to stock 266 the computer STILL resets at POST and I still get the red screen that says everything was reset to stock, even if I have already set everything to stock.

Any ideas whats up? I had my OC'ing settings set in stone for a while without any stability issues and now it seems like my computer cant POST without resetting to "safe" fsb/voltage settings.

Latest BIOS?

Start by disconnecting everything (hdd, optical, USB, PCI) except CPU and RAM. Boot up and see if it boots fine. If yes, add one peripheral at a time, boot, repeat. See if you can narrow down what, if anything, is causing the error.

You may even have a dying CMOS battery.
