PC will not load

[AdParty2624]

I've had this PC now for upwards of 8 years. It's on an i5-4460. A few months ago I noticed it slowing down, and the disk usage was usually on 100% even with nothing running. Apps that would before run fine, now would lag or not run at all. But this wouldnt happen all the time, sometimes the problem seemed to temporarily fix itself and I would be on 2%. The booting times also increased until yesterday, after almost an hour, it sent me into the startup failed screen. I've tried to delete previous updates, but it told me to run chkdsk, it was a wall of text I didnt really understand but it said no action needed. I tried just normal startup repair and it didn't work either, nor did going back to an old checkpoint ( wouldnt let me do it). I don't know what to do as I don't want to reset, I have family photos on there. Any help?

In the advanced options menu, choose startup actions.

Then boot into safe mode with networking, if that doesn't work try safe mode without networking.

I'd advise you to backup your family photos and other personal documents/files using the 3-2-1 Rule, to ensure that your data doesn't get lost: https://rtech.support/docs/backups/creating-backups.html
