Computer shuts off at startup

[smeezekitty]

has anybody ever thought that the new graphics card may be ether overheating
or malfunctioning causing tee system to shutdown?
do you happen to have onboard video?
if so enable it in the bios and remove the video card
if not do you still have the old one?
if so  try it instead
