bobb64, you have overclocked your cpu. I'm not sure of the exact number, but your xp2400 should run about 1800 mhz. Many don't understand that the AMD's don't run at the same speed as the number in the name. In other words, there was nothing wrong with the reading you were getting.
To reset the BIOS, you will need to clear the cmos.
There are different methods for accomplishing this with different motherboards. The simplest answer that I can give is remove the cmos battery from the motherboard. It's the round (about 3/4" inch wide}
battery. You need to do this very carefully, as not to damage the small clip that holds the battery in place. Also try not to touch any other parts on the board. Ground yourself by frequently touching a bare metal part of the case, in order to avoid any electro static damage to your computer.
If you have your motherboard manual, the instructions for this should be found there.
Leave the battery out for a minimum of 5 seconds, (I usually leave them out for 30+ seconds) then replace it and reboot. You should be able to re-enter the bios and check your clock speed. It should have reverted back to the default settings.
Hope this will help, Good Luck.
I am currently running xp2400+ amd
64mb gforce gcard
My problem is my xp2400+ was only being recognised as a xp1800+, so i tried increasing the cpu clock speed from 100 to 130.
But after this had been done bios wont load up and the monitor doesnt show anythin on the screen.
The hard drive is ok as i am using it in mmy old system just now.
any help apreciated!
