I've had this issue for a while now, sometimes my PC would crash (and sometimes freeze in the middle of a session which I would then hold the power button to make it go to sleep and then again to wake it back up) saying UNEXEPECTED_STORE_EXCEPTION or CRITICAL_PROCESS_DIED, and then my PC would reboot saying "Hard Drive Not Installed", what I kept doing each time was opening the device and reseating the SATA connector and then it would work. Another issue with my device is that if I left it alone for several minutes, it would restart by itself, sometimes into the BIOS diagnostics test (which would then beep a really annoying tone afterwards). Any solutions?
Possibly a hard drive problem. Restart the system and at the Dell splash screen start tapping F12. Run full diagnostics and pay attention to the hard drive results.
I ran all of the BIOS diagnostics for the hard drive, and no errors have been found, other than the log saying "Fail PSA, v4306.13 error 2000:0155, hard drive - not installed" for each time I came across the issue. I also performed some chkdsk commands and they all said no errors.
