hi
a bad dc adaptor can cause this issue
check the dc connector
remove the keyboard
check the thermal paste or the silicon pad
remove the memory module and try with another good ram

Re: Toshiba C660 shutdown

it seem to be GPU issue, but before going there , try to see with your DMM if you get 1.05v
