How to reset black screen PC for hardware problems
The first piece of advice I would like to give you to solve the problem of black screen starting up, is that of start your computer with just the basic components, that means RAM e processor. Everything else must be disconnected.
Therefore, remove hard disks, optical drives, such as CD and DVD readers, media for reading memory cards, any PCI Express cards and finally the graphics card if your computer has a dedicated one. In this way, the system will load the internal one.
If the problem is resolved and the screen turns on, you will be stuck on the first screen. Since there is no hard disk, the boot procedure will not be able to continue, you will therefore be informed of the lack of a storage medium. In this way, you will have the opportunity to understand which component is causing the error.
Try to reinsert the previously removed devices from time to time until the malfunction recurs.
Found the manager, check compatibility with other installed hardware. Lists are usually available to consult on peripheral manufacturers' websites. If, on the other hand, the screen continues to remain black, focus your attention on the RAM. A failed module can prevent the computer from starting correctly. If you have more than one, remove the rest leaving only one bench mounted. At this point try them all individually until you find the corrupt one that doesn't allow your PC to boot smoothly.
If even so the PC screen stays black during startup, brings the PC to assistance where they can verify the perfect functioning with advanced tools.
