While using the system, mostly when browsing the web using the Chrome browser, the system crashes - the screen goes black, but on the background there is activity, so the system works, just the GPU "dies". Tested OSes include Linux and the ChromiumOS. Crashes are mostly random, but "sure way" is browse to http://codeanywhere.com/ and logging in using latest stable/beta/dev Chrome, or trying to enter Chrome Web Store using ChromiumOS.
System hardware is Toshiba Satellite L300 laptop.
I am attaching relevant crash file from /sys, dmesg and Xorg.0.log
