Unexpected blue screen. It suggests hardware issues and happens frequently today.

I skipped the ram test because Microsoft said it takes several minutes, but actually takes several hours (64GB).

Each time the system crashes, the foreground process is unresponsive and followed by high disk usage. I enabled bitlocker on my c drive, and it failed to mount in my win to go system (I prepared for emergency), thus it indicates the drive might have a problem (but the smart report everything is ok).

Currently, I'm recovering the encrypted data from the c drive. Then, test the ram and see what's going wrong.
