Hi,
Recently I changed some components of my PC, but kept the architecture, so simply switched on the computer after the change and everything worked smoothly. Next, I changed my 500 GB sdd system disk (C:) by a new M2 NVME 1 TB one. With a cloning program, I did the change, started up the system and, again, everything worked well. The computer (Windows 10 PRO 1909 release) has been working without any issue for one month or so. Last 25th September, I opened a program (it doesn't mind which, it is a game), and after a few seconds it throwed me to the desktop, Tried again, and to the desktop. So I restarted windows, thinking that would work it out. On restart, the system said it had found errors and was trying to repair them. When finished, restarted automatically and BSOD with code 0xc00021a. From them on, nothing worked to start the system again, I always ended with that bsod. I tried every repair option by windows troubleshooting environment.
As I do baremetal copies of my system everyday, I restored to the day before. Again, at start, BSOD with same code. The day before, same BSOD. Finnaly, I was able to restore to a backup from 6 days before. System started up, and everything worked again. Next day, I opened Word, and tried to open a document. At the moment I choosed Open, it crashed to the desktop. This time, I was able to see a notification in notification bar: Restart system to repair disk damage. And from them, everything begun again. BSOD, and nothing worked.
So I thougt it should be a virus or a disk failure. I recovered a working copy, and made a full scan with Windows Defender and Viruscan, Nothing found. So I proceeded to change the disk. I recovered to the working copy, and reinstall windows keeping data and programs. It seemed to work, because while the damaged disk message appeared after just a few minutes, this time it was four or more hours without the message. But it finnaly appeared. This time, however, when restarting, a repairing C message appeared and after that, system starts and no BSOD. But message keeps appearing again and again.
Now, CHKDSK /Scan reports 'The volume bitmap is incorrect'.
sfc /scannow find some errors and tells they have been corrected.
DISM /Online /cleanup-image /scanhealth find errors, and DISM /Online /cleanup-image /restore-health tells they have been corrected.
CHKDSK /F /R tells that errors have been corrected.
Today, all those commands report no errors. But I am afraid it will happen again. What can be the cause and the solution for not happen anymore?
Format and begin from zero is a big headache, because I have tons of applications and configurations. And it doesn't guaranty not happen again if I don't find the cause of this.
