Computer Turns On For A Few Seconds Then Turns Off?

i am able to turn my computer on for a few seconds but then it automatically shuts itself off after a few seconds but the thing is after letting it sit for a couple seconds it says something about how the clocks on my processor have been overclocked too high and asks if it wants me to restore them, so i do that and then the computer works fine, but then when i turn it off and turn it back on it does the exact same thing until i get that message again.i've tried manually reducing the clocks on my cpu even though they were already at stock clocks and that didnt work

system specs:

windows 7 ultimate 64bit
intel core 2 quad q6600 @ 2.4ghz standard clocks
4gb ddr2-800 ram
ati hd 4760 1gb ddr3
