This is probably a driver issue.
What CPU and GPU is on your computer?

It appears the resolution is down to 800x600 or something.
That's what my Debian looked like the other day after I upgraded the Motherboard firmware. Upgrading the firmware reset all settings to default including enabling Secure Boot. Perhaps you need to disable Secure Boot in computer settings or boot with the other Debian entry. In my computer's boot menu, I have two entries for Debian, one for Secure boot disabled and one for enabled.

CPU: Dual Core AMD Turion II Mobile M500 (-MCP-)

I ran inxi -G and got this::

Device-1: Advanced Micro Devices [AMD/ATI] RS880M [Mobility Radeon HD 4100] driver: N/A 
           Display: x11 server: X.Org 1.20.4 driver: ati,vesa unloaded: fbdev,modesetting,radeon 
           resolution: 1152x864~N/A 
           OpenGL: renderer: llvmpipe (LLVM 7.0 128 bits) v: 3.3 Mesa 18.3.6

Since it's an AMD cpu - it's likely your OS will need non-free firmware installed onto it.

What is the output of:

dmesg | fgrep direct-loading

This will show if firmware files have loaded or failed to load.

Ran it and got this::

 [   13.806314] usb 1-2: firmware: direct-loading firmware carl9170-1.fw

Also I tried to add the non-free source to my sorces.list text file but I cant edit it without root and when i run su su my system passphrase dosent work.

am i just dumb??

You're going to have to take a closer look at dmesg.
Try this:

dmesg|grep -iE 'direct-loading|firmware|amd|radeon|unloaded'

The output seems to be usb-related and shows no problems with loading the firmware

Also I tried to add the non-free source to my sorces.list text file but I cant edit it without root and when i run su su my system passphrase dosent work.

I don't think you need to bother with changing /etc/apt/sources.list.
This is because your machine seems to be able to run a 'pure' version of Debian 10 - even if you do have an AMD cpu.

If you do want to make changes to /etc/apt/sources.list, then open a text editor as root.
For example:

su

Hit enter and input your root password.
I always use gedit so:

gedit /etc/apt/sources.list

This will open your sources.list file on gedit.
Make your necessary changes, press save and close gedit.

I don't think you have a driver issue.
Why does your pic show package aptitude from the debian page?
This package comes pre-installed with Debian.

What desktop environment are you using?
Consider changing the desktop environment on the initial debian login menu - and see if that makes a difference.
Also refer to ondoho's post.

I Belive i was just exploreing the Debian site at the time to learn about the os.

Im useing xfc as my environment.

Also i seem to recall some one saying some where that my system is loading from my cpu? whats THAT mean?

I I used you advice and can now use nano to edit my sources, Thank You
