Can't install Linux Lite

[harryf]

I have been using Lite for a few months with no problems, but recently my motherboard died and after I replaced it I could not get the PC to boot up (black screen). I tried the Installation DVD to get live mode and that only works in safe mode. I tried to install from safe mode and it seemed to install ok but after the re-start it hung up with a black screen. Is there anything I can check when in safe mode to find this fault? Please keep any advice simple as I am not very good with Linux.

Update:
I got Lite to install finally by removing the Graphics and wi-fi cards. I then replaced the wi-fi card to get updates, but I get an error. Here is the error log it gave me:

===========================
Install Updates Error log
===========================
Install Updates could not fetch the package cache information lists.
Go to https://www.linuxliteos.com/forums/ and paste the log below into a new or existing thread for assistance.

============ Log ===========

Reading package lists...
E: Could not get lock /var/lib/apt/lists/lock. It is held by process 2774 (apt-get)
E: Unable to lock directory /var/lib/apt/lists/

I have no idea what that means - can anyone help?

I think there was another update or process running and locked the files.
If you see another Terminal opened or an update/driver update/app update window opened, close those.
Worst case, wait maybe 30 minutes (that should already be passed looking at the time ), reboot your computer, try again when everything has loaded.

Maybe my post is useless but at least I tried

Thanks Dead, I don't what I did but I got update to work. The motherboard video seems to o/p hi res so I may not need to fit the graphics card now.
