MacBook crashing during login

My Macbook keeps crashing while loging in, or even before I enter my password to log in. Sometimes it comes up with the writing on the screen as per the app ached photo, but often doesn't even get that far.

It started when I was transferring some files via LAN and the transfer froze, so I tried to cancel it, but then it wouldn't cancel, so I relaunched Finder via the 'force quit' menu.

Could somebody please tell me what I could do to stop this happening and resume using the computer? I have many files that have not yet been backed up.

It is a mid 2013 MacBook Pro:

Processor: Intel Core i7
Processor Speed: 2.3 GHz
Number of Cores: 4
Memory: 8 GB
Video Card: Intel HD Graphics 4000
Video Memory:
Video Card: NVIDIA GeForce GT 650M
Video Memory: 512 MB
OS: latest update as of 17 July 2015

Thanks in advance for any help with this issue!

Try to boot into the recovery partition. From the 4 option menu select Disk Utility. Run Disk Utility>First Aid.

Ciao.

Thanks OGELTHORPE, I did that and said volume appears to be fine. I tried reinstalling OSX with recovery partition, and now it's stuck logging in and doesn't appear to be loading any further over the past few hours. Will leave it there overnight to see what happens.

OK, for whatever reason the computer completely froze when installing the OS, and was unresponsive even after leaving it for over 24 hours.

I crashed it by holding down the power button and ever since that everything seems to working perfectly fine, which is about two weeks now.

Still unclear what the issue was, as all my files and settings have been left untouched.

Thanks again for your suggestion, though.
