    Have a acer extensa 4210, power running through machine, fan turns on and then slows down and no display. OS is xp.
    Tried external monitor and no display, removed cmos battery and refitted and still no display on notebook monitor or external monitor. Any more tips and tricks that I may have not done or any help to solve this fault.

    Sounds like your GPU has failed which can only be repaired by fitting a complete new motherboard.

    The only thing you could try is to remove the RAM (with power disconnected and battery removed) then re-connect the power and switch on with just one of the RAM sticks fitted, then try with the other one (if you have two). If you only have one RAM stick try to borrow one to test it. This is a long shot as when RAM fails it usually still shows something on screen.

    Just did what you said, it has two ram slots but only one ram. I tried with one extra ram that I had in both slots and still no display. My gpu must of failed, have to replace the motherboard.

    Try booting with no RAM installed and see what happens.

    Unfortunately it does sound like your GPU has failed. You would only get a beep with no RAM fitted if the motherboard has its own speaker.

    No output when connected to an external monitor and no change with all the RAM removed so the conclusion has to be a dead GPU or a fault in the associated circuitry or power supply. A new motherboard will not be cheap unless you are lucky enough to find a used one, a new PC would probably not cost a lot more than a replacement board especially if you have to pay someone to fit it.
