Lag, freezes, and takes around 5 minutes periods to register the commands. Please help!

Hello everyone, I’d like to ask for some help with my Toon Boom Harmony Premium.

And here are some of my specks of my laptop: It’s seven years old, it’s a toshiba satellite

You see, whenever i open my Harmony, it lags. Even when i try to make sure other things aren’t eating the ram in my pc (I don’t have other programs or browser open). Even when i haven’t started the project, the window to make one lags, when i try to draw it just (once again, and sorry for the redundancy) lags. I can’t honestly work like this, and i don’t understand why it does this. I have Uninstall it and install it again, try to update my windows, update my graphic card, and still nothing, and im just so confused of why this happens. Just to give you an idea of how ridiculous this situation is, Autodesk Maya (The 3D model program) runs me smoothy.

Im not too tech savvy, so my apologies if i’m not explaining myself properly. I just, don’t know what else to do! Please help!

Which graphic card model is on your seven year old computer?
Was it working well previously?
What happened around the time the lag started happening?
