it might help if you post inside a code box...the list of errors...try /var/log/dmesg for a start?
Can you press control + alt + F1 to get back to login messages and see them on the screen?
To get back press cnt + alt + F7
If you can see them on the screen but not in logs....install fbgrab....apt-get install fbgrab
fbgrab -c 1 /root/errors.png
