blackscreen when startingup cursor jumping allover the place need help?

The cursor jumping all over the place could very well indicate that the track pad is faulty.
If the screen is black and stay black for a long time, or for ever, it's often that Windows just can't start, usualy because of a missing or corrupted essential file.

At 12 years old, as there is at least some hardware related problems, it will be cheaper and easier to get a new one. That new computer will be MUCH more powerfull. Something like comparing a Ford model T to the latest Ferrari.

For your files on the actual drive: Take it out of the computer and install it in an external enclosure and use it like an external drive.
