I'm not sure I'm posting in the right place, but I'll ask anyway. Today I decided to clean my PC, and everything seemed fine until it got to loading Windows. First, it takes a really long time to load, and then the screen goes black and nothing happens. I can access the BIOS without any problems, all my peripherals work, the monitor is connected via the graphics card, and the PC doesn't turn off immediately after pressing a button, only after holding it down. I'm running Windows 10. Does anyone know what could be wrong? (Sorry for the errors in the text, I translated it using Google Translate)
