I've flashed the rom by myself,i ddidn't bought it from Gluglug.
I've tried various distros(Gnewsense,Musix,Debian,Trisquel 6,even Mint).The
only two that booted in Live mode without problem were Trisquel 6 and Mint.
At one point i kept the laptop on the Libreboot menu few times for 5/10
minutes and it was shutting down as well due to overheating.
After i've done a proper fan cleaning with an aridust can the problem seemed
to be solved.
Then again shutdown while i was using:
Icecat
Abrowser
DosBox emulator
for the browers seems to be caused by Gnash
let's see what's happend next
