What's wrong with my computer? And can I fix it?

My windows 10 desktop is acting up. My mom told me there was an update so she tried to update it. We can sign in but it's black with a mouse. Sometimes beside the mouse there's that loading thing. And if we let it sit over night or a few extra hours it will load my background phot but that's it. No icons, no interaction that's possible. We can't even click start, or get task manager open. Any ideas? I've tried a lot of things already, nothing seems to work. At this point I'm ready to factory reset it but my brother has all his iPhone photos on there, I do also.

See if you can start it in safe mode.

It seems like the computer is having a hard time loading the operating system. That means that there's probably a problem with the hard drive or the RAM. I would recommend trying to start the computer in safe mode (press f8 while the computer is booting). Sade mode only loads the basics of the operating system so you might have better luck there. If you are able to load into safe mode you should be able to at the very least transfer your photos to another drive. I would also recommend logging on to your icloud (same as itunes) account to see if your photos may be backed up there. I think that it is most likely a hardware problem, so a factory rest would not benefit you at all. If you are uncomfortable troubleshooting/ working on your computers hardware I would take it to a local repair shop.
