Lenovo Y580 Notebook will not turn back on, just a blank screen and the computer restarts every 3-4 seconds, does not post. No previous symptoms. I tried both sticks of ram individually and removed the hard drive and it does the exact same thing. Could both sticks have died at the same time or is it more likely a MB issue? Each attempted boot lights up the power button, keyboard backlight and spins the DVD player before restarting. When both sticks of ram are out the computer stays on, no rebooting. Its DDR3 1600 ram, a 2 and a 4 gig stick, made by Ramaxel. No idea why Lenovo didn't install matching ram, has worked flawlessly for 4 years though.
