960 Pro 512 GB M.2 SSD - inaccessible boot drive error - Help please!

[ Edited ]

I have a 960 Pro 512 GB M.2 NVMe SSD installed on a Gigabyte GA-Z270X-UD3 motherboard (latest F7 BIOS) in a system built about 2 months ago.  Also installed are 16GB Corsair Vengeance DDR4 RAM, a Samsung 850 Pro SSD, and three HDD's.  The 960 Pro is the boot drive with Windows 10 loaded.  The motherboard has only one M.2 slot.

 

This system has been working very well for over two months, including last evening.  This morning, the system would not boot up.  The Gigabyte logo screen stays on longer than normal, one beep (normal) is heard from the motherboard, the Windows spinning dots spin longer than normal and eventually the system gives an inaccessible boot drive blue screen, with restart and other options.  On selecting restart, the motherboard beeps 4 times and boots into the BIOS screen, which shows a no ROM loaded message.  (I believe the 4 short beeps may be a "real time clock malfunction" - I'm not positive though.  The system time shown in the BIOS is accurate.)

 

The 960 Pro does show up on the various BIOS screens having to do with drives installed, boot drive order, etc.  I've tried loading optimized default BIOS settings, reinstalling the BIOS software, removing and replacing the CMOS battery (voltage tested above 3V), and made repeated reboot attempts in both normal and safe mode through the windows tool.  But the system just won't boot up - always behaving the same as described above.

 

There were no lightning strikes or electrical outages overnight.

 

Is something wrong with my 960 Pro drive?  Help please!

 Hi userHefAI9Xbew,

 

In order to test the SSD itself, have you tried a clean install of windows? the issues you are having may be OS related.

It´s related to the latest Firmware bug....

 

-mod edit-

OP's issue is unrelated to Firmware issue.

Hi MisterAT,

 

Unfortunately, Thats incorrect. The Original poster's issue is a booting issue after the drive was working fine. Not a firmware or freezing issues as other affected users have reported. I believe the OP may have already contacted us over the phone for further assistance.

Thanks for your replies.

 

I did contact Samsung support by phone and described this issue.  They authorized an RMA of my 960 Pro, but suggested that before I send in the drive, I try a reinstall of Windows.

 

I tried a Windows Reset, rather than a clean reinstall, in an attempt to preserve as much of my software setup as possible.  The Reset appears to have fixed the boot problem, and the system now boots normally.  I am very pleased with that.

 

The system is now running normally.  However, Windows Update seems to have something wrong with it, as it repeatedly fails to successfully install the most recent update of Windows 10, Build 1709.  It is installing other updates, though.  I hope I don't have to do a clean reinstall of Windows, but that may be necessary if the Update issue continues.
