Just had my desktop crashed again. This time I doubt it's hard drive related.
Looking up 9f code, this BSOD is likely caused by some drivers not able to support sleep mode, which my station is doing this time, since the new fresh OS install.
Blue screen of death was not observed, but I realized it once I saw a message popup after login in when I came home just now.
I'd have to take the sleep mode off. (from 2 hours to Never)
