blue screen bios error


I have an L55 running windows 7. Blue screen appeared, said something about Bios, cache, shutting down computer.

Not sure if related but recently updated to windows 10. Lost computer functions and reverted back to windows 7.

Seemed to be fine for a few days then got the above blue screen message.

On startup after error I can see the logo for a brief second then black screen.

Restarted while tapping F12, ran diagnostic,  got pre boot system assessment build 4129 error code 0142.

I look forward to comments.


Hit continue and it is finishing now.
