Post subject:  Random System Freeze....Nothing Works

After installing latest 64 bit UberStudent xfce on my HP Pavelion 15 notebook yesterday after an hour system freezed,Nothing worked.by mean nothing I mean keyboard,mouse,alt+ctrl+dlt , atl+ctrl+(f1 or f2 or any other tty) , alt+prt sc+REISUB . even after doing an first update problem persist.problem sometimes occur even in lock screen.This is a ubuntu related problem.previously i tried Ubuntu 14.04 LTS,Linux Mint Cinnamon Sarah.These two also had same problem.But latest 64 bit LXLE which is also Ubuntu based ran very smoothly.
tried latest debian 8, 64 bit with gnome,kde,xfce,cinnamon everything on a single system but never had a single problem.
CPU usage is mostly below 10%
thought might be ram problem so I tried overloading my 4GB RAM.but even at 100 mb free ram system worked perfectly.
I think might be a GPU issue.
so i attached some log files from /var/log and output of lshw on terminal.
This is a great distro and dont want to leave it.pls help me ASAP

This seems like your machine may be dying. How old is it?

How long ago were you running Debian with KDE, Gnome, and Cinnamon?

I don't see anything in the logs that looks like a crash. If it's possible to run the system again until it freezes, reboot and then immediately re-uplod the logs, I can look again. You can just run this line to gather the logs:
mkdir "$HOME/Desktop/logs" ; sudo cp /var/log/syslog "$HOME/Desktop/logs" ; cp /var/log/Xorg* "$HOME/Desktop/logs" ; cp /var/log/dmesg "$HOME/Desktop/logs" ; sudo chown -R $USER "$HOME/Desktop/logs" ; chmod 755 $HOME/Desktop/logs/*
