Hello, I made some posts here a while ago that my PC not displaying anything (black screen) after leaving for a while and coming back, and even after restarting there’s still no display…

Now I have restarted it a couple times and waited for some hours

And now it works again

I turned off fast startup and changed some settings in the sleep mode and I hope it works

Now I have read that the problem is my BIOS version, now I’m trying to update it however I don’t have a USB, is there any other alternatives?
