my imac osx snow leopard turns off and wont recover
What model do you have, and exactly what do you mean by turns off? Do you mean it just spontaneously shuts down while you are working? And then you cannot restart?
I have an IMAC 21.5"/3.06/2X2GB/500GB/4670 year2010 with snow leopard MAC OS X 10.6.8 Yes it spontaneously shuts down while working and I cannot restart unless I disconnect the power supply.
Start by doing an SMC reset...sounds like a power-related issue.
