A few days back my laptop suddenly went blue and thereafter started receiving 3FO Error stating 'Boot Device Not Found' and when I tried Hard Disk check (after pressing F2) it said no hard disk found. The service centre guy said that the hard disk (SSD) has crashed and you need to replace a new one.

I purchased a new SSD and installed it (using the bootable I created and installed windows). But now again, the same thing happens. Out of nowhere, the screen turns blue and the system restarts stating the same 3FO error. Although now if I press the power button and restart the laptop, it starts working fine, and the loop continues.

 

Please help. I don't understand why the problem still occurs (now that I changed the SSD).

FYI: The laptop has been heating more than it used to for a couple of weeks.harddisk3f0_sod.jpg
