computer randomly resetting itself

Hello there.
I am having a little problem hopefully easy to solve.

I have a dual boot system which is the same as previous threads.
One disc (ssd) has a Win7 installation with internet and the other disc has a Win7 installation without internet.

The disc with internet has been restarting itself since about 3 months ago but I did not pay attention to it because it was nothing that bothered me, it was just too occasional.

Today it started restarting until it would not boot up. I saw the startup repair option and I ran it.
I don't remember what happened the thing is that I could only boot to the other disc.

Please see attached picture attached of a message Diagnosis and Repair details.

From here I would not know what to do

Thanks a lot.

Try to do this, that will probably help you.

thanks for reply. Unfortunately bootrec did not work.
I gave up now. I am going to reinstall from scratch tomorrow.
thanks a lot

Strange.
So I went to reinstsall windows but Chekc disk started automatically.
It is still running like for 30 minutes with "file record segment is unreadable" and lots of numbers incresasing, ....

I want that to stop, I am thinking in hard resetting the computer.

The faulty storage is an SSD 160gb. it is like 3 years old.

Any thoughts?

Thanks
