Crashing

Well the story is as follows. Downloaded the iso image for Debian wheezy version of Linuxcnc, put it on dvd with intention of installing it to a newer pc (i3 530 @2.9Gh, HDD wd6400ars, 4GB ram, gt250 gs 1GB). Installation went on just fine and then it just won't open. I read that maybe that maybe partitioning as ext3 manually instead of ext4 might solve the problem, tried it, didn't work. I read that changing sata mode from ide to ahci might work, didnt.
I redid the process with the same results. Because writing every message that popped up would be painful I attached several photos of the system starting up and how it results in a pixelated crash. Has anyone encountered something similar?

there is a Try Without install option on the DVD try that first
then reboot and install

Tried live version results in the same screen. Attached are photos of boot sequence

Thank you all for your imidiate support. Its great for newbie like me to have back up!
Indeed Debian Strecth(linuxcnc-stretch-uspace-amd64.iso) worked. First tried the live version and then installed, both went smooth. However another problem came up, there is no access to the internet, it wont access any internet page. When installing, a message popped up saying that the network is probably not using DHCP protocol and later when asked if i am installing from a netinst CD to choose a mirror i chose no. I would very much like your experience if i did anything wrong and to set it properly.

Today was quite a day. I tried to resolve the hardware issues. At first i changed paste of CPU which hadn't been changed for at least 5 years cause it was like concrete, to resolve the overheating issue, and i think it was a hit. Tried Debian wheezy live version got the same pixelated screen. Then i changed sata HDD because there was am indication of it being damaged, got the same screen. My last chance of a usable pc was a GPU problem. Downgraded to a Geforce 6600 LE, but long story short, 4 hours now, after 5 reboots and everything runs smoothly, memtest came up clean.
Is there a test you would suggest to check the system (cpu temperature etc.)? However the weird Internet behavior continues... for example i have access to linuxcnc forum, youtube, wikipedia, gmail but not linuxcnc.org, yahoo, github, kathimerini.gr (newspaper site from my country-Greece), i get "Server not found". I can't understand what is going on, and i am sure its not a network problem since i connect my win10 laptop to the same network and it's all good. Any thoughts?
Thank you all for your help!

I was also tru=ying to install Linux on my PC while running the process, it was showing that there is a TFGHT error. I have searched a lot on the Internet about the error and finally, epson error code 0xf3 resolve the entire issue.
