Error starting/installing Linux Lite 3.8 and 4.0

[Feainnewedd]

I have a Dell Inspiron laptop with 4GB of RAM and an i3 processor. It used to run Linux Lite 3.8 just fine. Now I installed Linux 4.0 and it hasn't really been working since then. I was able to run it on 4.0 at first, but now it doesn't boot and just shows a black loading screen.

I tried inserting the flash drive installer to boot my laptop in safe mode, but each time I do so, the machine just freezes as shown in the photo below. The same thing happens when I insert my 3.8 flash drive installer and attempt to boot in safe mode.

Can anyone please help? I can't use my laptop
