I am trying to remember a sci-fi film I saw briefly as a child. It was probably in the '80s/'90s.

I have hardly any memories, other than a man who was piloting a spaceship with an onboard computer.

I remember a scene where it crashes and the lights and everything inside turns off, including the computer, and he is screaming the computer's name to try and turn it back on. Unfortunately, I can't remember the name of the computer. I think the voice was female.

I think he needs the computer to be able to take him forward/or back in time. Unfortunately that's all I can remember, which I know isn't much, but perhaps someone can remember it?

It's not *2001: A Space Odyssey*.
