Minecraft Version Trouble

Hello, I am BlissfulKnight. I have been having a problem for the past month or so, where the versions 1.3.1-1.5 will not load up. If delete my whole .minecraft folder, which I've tried, the versions will start to load up just fine, display the Mojang screen, but then a crash screen will come up. Here is the log if you need to view it. I used version 1.4.5.

Minecraft has crashed!
----------------------

Minecraft has stopped running because it encountered a problem; Failed to start game

A full error report has been saved to C:\Users\Cy\AppData\Roaming\.minecraft\crash-reports\crash-2017-04-04_17.57.58-client.txt - Please include a copy of that file (Not this screen!) if you report this crash to anyone; without it, they will not be able to help fix the crash :(

If I already have tried and failed at starting up any of these versions, if I start it up, the launcher will simply stop responding, and Minecraft will not start up. I have tried deleting the versions in the versions folder, I have fully deleted the .minecraft folder, and I have tried many times on all of these versions to start them up. If there is anything I can do to get these versions to start up and function again, please inform me about it. I do enjoy playing these versions of Minecraft.

Sincerely, BlissfulKnight.
