graphics display at installation of 20.04.1

My question seems very similar to this question from someone five years ago: Ubuntu Graphics Not Loading Properly even after fresh installationCan someone give me a current solution to this problem for Ubuntu 20.04.1? The latest Windows 10 update made my HP computer crash. I did a factory reset to the original Windows 7. I was able to install Ubuntu 12.04 LTS from an old DVD alongside Windows 7. When I tried to install Ubuntu 20.04.1, both from a DVD and from a Rufus USB stick, the graphic distortion began and I don't know how to straighten it out. I really don't want Windows; I want an up-to-date functional Ubuntu Desktop as my only OS. What do I need to do? thank you so much!

More information about the computer and the graphics card: HP Pavilion Slimline Model #: s5503w, Software Build #: A1NAv6PrA8, Windows 7 64-bit, purchased in 2010. I upgraded myself to Windows 10 in 2015 and installed a new graphics card at that time: NVIDIA GEFORCE 309.08 DRIVER.
I have just re-installed Ubuntu 12.04, which is displaying normally, and the computer now says "NVIDIA accelerated graphics driver (version 96)"
The Disk has 316.7 GB and Memory has 2.7 GiB.

I opened DASH and clicked on TERMINAL, then entered the command:   sudo lshw -C display this is the output:

ubuntu@ubuntu:~$ sudo lshw -C display

thank you so much for your patience and your good help!

I am in Ubuntu 20.04 in nomodeset ! Thank you for getting me this far! I have installed updates that have recently been added.

I have downloaded NVIDIA-Linux-x86_64-304.137.run. I have used the command chmod +x filename.run to make the run file executable. I have used the command sudo ./filename.run to execute the run file.

The error message I am getting is:

ERROR: Unable to find the system utility ld; please
make sure you have the package 'binutils'
installed. If you do have binutils installed,
then please check that ld is in your PATH.

I have looked on GOOGLE to find out how to do this, but none of the attempts I have made have worked.

Is anybody able and willing to point me in the right direction for this step? thank you so much!
