After startup logo, screen goes black

When I was on my laptop, my screen suddenly became black. And now when I try to startup my laptop, it first asks if I want to do the startup repair or just start normally.
But when I choose startup repair, it just loads and then my screen blacks out again. And when I select start windows normally. The normal windows logo appears, but then a BSOD flashes and then my screen goes black again. It doesn't shut down or anything. My screen just stays black.

What should I do?

Oh, it's just restarting after that. So I'm stuck in a loop, can anybody help?

Troubleshooting Windows 7 Failure to Boot

Okay, I will try this. I will let you know if this worked.

Thanks in advance!

I can't even get into bios menu, and system recovery doesn't start either. Help

You may need to switch to bootable media provided in tutorial. F8 System Recovery Options may be corrupted or the OS inaccessible until you do.

Persist in tapping the key given for BIOS setup to see if you can reset BIOS to defaults.

What is the exact Sony model?

My exact system model is a SVS1511C5E, the hotkey should be F2, but it brings me to a menu where I can choose:
Windows 7 or Windows Memory Diagnostic.
I can also click on F8 to go to the advanced menu.
