Solve : PC won't load boot disc?

1.	Solve : PC won't load boot disc?
Answer» I shut down by turning it off at the button, instead of a proper shut down and I get a "Your CPU has changed or over-clocking". I had seen this before, and seen how the person had fixed it (or so I THOUGHT), I went into BIOS and altered the frequency. I re-boot and my monitor stays on stand-by. I try restarting and un-plugging the AC adapter at the same time (don't ask...) but it seems to work. I restarted, and the same "Your CPU has changed or over-clocking" message. I download EPOX motherboard drivers to a bootable floppy, but it won't even load that. Does ANYONE have any ideas?go back into the bios and chose setup DEFAULTS option save and exit it..
