Reset BIOS to factory.

After that, return it wo delay.

Okay I have isolated the problem toit only occurs when I am running off of the ac adaptor when I unplug it, it is working at normal speeds, anyone know what causes that or why

Windows' Power Settings or Dell's own Power Management. There is a setting somewhere that says, If on AC, DO THIS, and if on BATT, Do That.

thanks just looked at all my setting's now when I plugged in my ac a notification is popping up stating that the power source cannot be determined and to use a dell 45w ac adapter,....but I am using the one from the factory the notification also states the the computer will not charge and will run slower because of that... but yet it still charges but it does run a lot slower is something wrong with the cord ?

Then either there is something wrong with the charger or the laptop's charging circuitry itself. If you have another charger of the same or batter rating and same plug, can try that, other than that you will have to deal with Dell again.

Some laptops come with a 12V car charger, can try that also.
