Why isn't my the old republic game working on my computer?

It installed and was working on this computer just fine when I used to play, recently I reset my computer and erased everything. I downloaded Star wars the old republic and installed eerything. When I try to lay it it opens just a sliver of a screen of it and never fully opens. I tried going in different resolutions and it does basically the same thing. In the photo you can see what's happening, it's a little box in the corner of my screen right now. It won't load either.
I have a a graphics card and all of the same arts of my computer that the game was playing fine on before.

Please help me figure out what the problem is. Thanks!
I have windows 10, it's a lenovo computer, and I have an hdmi connection to a 1080p hd tv Why isn t my the old republic game working on my computer

Was it running Windows 10 before? If not, then this might be a problem with the graphics drivers working in Windows 10.

Was it working over HDMI and at the same resolution to the same TV previously? I recently connected an old computer that was working on a 1080p monitor to a Panasonic TV, and it worked fine in the BIOS, but as soon as the OS started the picture was just a random mess similar to an old analogue TV with no signal.

I have subsequently tried it on a 720p LG TV and a 1080p LG TV, both of which worked perfectly.

If all the hardware including the TV is the same, I suspect you either missed or installed a different driver when after the reset.
