Hi - I have either a failing Windows 10 or a dead hard drive. I'm reasonably tech-savvy, but not literate on computer repair. I've googled a lot and read a lot, and tried a lot. Not really sure what any of it does, but I'm trying.
It started about 1 1/2 weeks ago. My pc was running extremely slow, so I restarted it. It spun on restart for a while - probably an hour while I did other stuff - so I forced it off with the power button. Started it back up and it took ewll over an hour to restart. I don't know exactly because I finally just went to bed. I ran a scannow and got one error, which it said it fixed. There were no drive errors and no unresolved problems. The pc was still barely responsive. I tried resetting Windows, but that got me stuck in a "diagnosing your PC" and "automatic repair" loop. I was able to get to advanced troubleshooting and ran a startup repair, then it finally booted. It's generally more resonsive now, but I'm not asking it to do anything. I looked at event viewer and I have a LOT of disk Error 7 and a recurring pattern of ESENT errors 454, 492, 471 - like 1 every second! Error checking and chkdsk show no errors. Ran another scannow and it hung at 58%. Trying to run a DISM cleanup, and it's been stuck on "image version: 10.0.10586.0" for an hour+.
It's a Lenovo IdeaPad Z570, about 5 years old.
