I open Photoshop, I open an image, I start editing colors. I think to myself "I need to change units to pixels instead of inches". I open the "Preferences - Units" menu. I approach the mouse and click on the selection box for units.... My screens go crazy suddenly and I get a BSOD...
The computer reboots, refuses to repair, complains it can't write on the disk. I launch UBCD, start TestDisk, it tells me my MFT and the mirror MFT are both completely messed up and the partition contents as well... Wow wow... What the...?!
Complete reinstall.
Thank you Intel GFX system driver.
