Laptop shuts Down

[Mohay]

Hello, I have a Lenovo t510 laptop,
When I turn it on, it's normal, but when it gets to the "starting windows" it shuts down, and after a couple of seconds, it turns on and do the same thing
It is windows 7.
Can anyone please help me

Disable automatic restart on failure by pressing f8 during startup and selecting that option. When it restarts again it will stop on the error screen whose information will assist us in finding the problem.

Thanks for the answer, but when I press f8 when it start, it says error stuck key, so I think f8 don't work with this PC

Win8 may startup too quickly to see the press F8 option during startup so you could also use the Advanced Boot Options in the system startup settings.
This should guide you thru it.

Finally I made f8 work. I switched the hard drive from the laptop who didn't work, and put it in my other laptop, and so I went into control panel, and activated safe mode starter, and out the hard drive back in the laptop who didn't work, and the laptop turned and I made it in to safe mode... Now what??
I tried to look at system restore, but apparently I don't have any restore files.
But now I can go to the normal windows, without safe mode, but sometimes it also turn off and goes crazy...
But if you have suggestion to do something in the normal windows, u can say

The laptop just shuts down if I use last known good configuration, and nothing happens when I disable automatic repair
