I'm having some problems, my computer is shutting down at random intervals, but from today it started to shut off rigth after the login screen.
It's a Toshiba Laptop. I thought it was the cpu overheating, but it's not. I tried also different RAMs and it won't work either.
Then I was thinking that it could be related to the ACPI but I tried adding the "acpi=off" in the boot/kernel and it shut off again.
So I really have no idea about what's happening. I still can boot in recovery mode but with the CLI only, as soon as I issue "startx" it'll shut down, sometimes instantly and other times after 1 o 2 minutes.
Other thing I tried was booting live from an USB drive. It also shut down, after the GUI showed and the drive lost its booting capabilities.
Do you have any ideas?
