STOP: 0x0000007В : How To Fix STOP 0x0000007B Errors (INACCESSIBLE_BOOT_DEVICE)
It's a harddisk driver that's faulty or missing. Most of the time when switchin from IDE to AHCI mode in bios. Or you need a special SATA driver which isn't installed yet.
All of this is ridiculous in this case. I think many thing are corrupt and that's why it can't find/load the sata driver.
Why not simply enable system restore points? Install 5 updates.... test if system is still stable. If not do a "system restore". install updates 1 by 1 after system restore. So you know which update caused it!
