That's a hardware error. Can you try running the diagnostics? (tap the F12 key at start-up and select diagnostics from the menu)

If the system has a graphics card, remove it and use the on-board video to see if the error goes away. If possible, try swapping in memory from a similar working system. If you can rule out memory and graphics, it's most likely that the motherboard is faulty.

I am having a blue screen error and anytime I restart my laptop it's always showing automatic repair , but nothing  happens afterwards it just switched off. If I turn it back on the same thing it comes up for some seconds and tells me it wants to restart when I try to restart it shows that I don't have any account on my laptop I've been trying it since and it's not working. What do I do?

I have tried multiple advice from the internet but nothing seems to work.
