cpu speed halved

Hi - I have an authentic AMD Athlon 2600+ processor running an xp system. Changed the setup options to 'optimum' performance. Since then setup screen shows cpu as a 1250 and the machine is behaving as if this is all the processing power there is (ie slow). Machine has 2GB ram and just been fitted with a new power supply.

Tried going into setup to reverse the change I made but it doesn't seem to make any difference

Any ideas?

Thanks in advance

Regards

Steve

Would a system restore help to a time when it was running ok.

Emachine?

No options to change FSB

Set the BIOS to default settings.
