I experienced my first BSOD on my W7 PC this afternoon, yay!
Everything was running fine, I started encoding a DVD and let it work (usually it takes from 1.5 to 2 hours to complete). When I returned about 1 hour later the monitor was showing this wonderful blue screen of death. Sooner or later...
Unfortunately I didn't take note of all the numbers, this is what I remember:

KERNEL_DATA_INPAGE_ERROR
0X0000007A
win32k.sys

I restarted the computer and I got this:

NTLDR is missing
Press Ctrl+Alt+Del to restart

I did it and I got the same message again, and again. So the computer doesn't boot anymore.

Can anybody suggest me how to proceed?
Any help will be appreciated.

Your HDD is likely failing.

Thanks for the reply.
 
My system drive is a SSD (Crucial M550), I have two Western Digital HDDs also. 
After the BSOD occurred I left the computer off for a couple of hours, then I entered the BIOS to check if the drives were detected correctly, everything looked ok so I tried again to boot and again I got the NTLDR missing message. Restarted, finally it managed to load the OS.
I ran sfc /scannow but no violations.
CrystalDiskInfo says all my drives are Good. I checked the SSD with HD Tune and the Western Digital utility (Data Lifeguard Diagnostic):
 
th_Crucial_reallocated_event_count_20160 th_Crucial_end_to_end_error_rate_2016032

I have been suggested to install Crucial Storage Executive and check the RAM with Memtest86.

Have you checked BOTH of the Western Digital drives with the long/extended test?

It is also possible for a failing hard drive to pass the short/quick tests and still fail the long/extended one.

 

SMART is just a predictive technology and often isn't very accurate (IME)

But, it's giving warnings on the SSD, so I'd have to wonder about that.

 

Here's a list of some free diagnostics (to include Memtest86+:  http://www.carrona.org/hwdiag.html

 

If it were my system, I'd pursue the hard drive angle first.  The warnings on the Crucial SSD are ominous IMO.

 

You also may want to check on any available firmware updates for this drive.

Hi and thanks to you too.

 

As a matter of fact yes, I checked both the WD HDD with the DLD utility (Extended Test) a few days ago (before the BSOD, in relation to this issue), they both passed the test.

I'll give a look at the link you posted, thanks.

After a couple of days off I started the computer today and I got the "NTLDR is missing" screen again.

I tried to restart a couple of times with no success.

 

@usasma

if I am undestanding correctly the site you linked, I should run one of Bootable Hard Drive Diagnostic programs since I can't access to Windows at the moment. But I don't see a specific utility for Crucial SSDs.

 

Any suggestion on how to proceed?

 

P.S.: the drives are all visible in the BIOS. Does this rule out possible faulty cables?

There are no specific bootable utilities for an SSD.

 

I would test by substituting a hard drive (or even another SSD) for the SSD and installing Windows on that (this is only temporary, so you won't have to worry about activating it)

Then see if the problem recurs.

If you don't have a hard drive/SSD to try this on, you can always purchase one from a store that will allow returns (that way you can get your money back if you don't need it).

 

Hard drives can still be visible in the BIOS, even if there is a problem with a cable.

BUT, if you don't have any cables handy (or can't borrow them), then hold off on that for now.

You can always purchase them from a store that will allow returns (that way you can get your money back if you don't need them).

I was planning to buy a HDD to replace one of my backup drives that seems to be at the end of its life so I could buy this hard disk, use it for testing and then use it for my backups. The only problem is it's a 5400 RPM drive (so no good as a system drive).

You can use that to test.  And if it's too slow (but fixes your problem) then you can get a faster drive (or SSD) and then wipe the slow drive and use it for storage.

I managed to boot Windows again (for some unknown reason one of the two hard disks was set as the boot device in the BIOS).
I checked the SSD with Crucial Storage Executive and CrystalDiskInfo, both programs reported the drive health status as good.

According to CrystalDiskInfo and Western Digital Data Ligeguard Diagnostic (Extended Test) both my HDDs are good.

 

So I'm back to square one.

Your choice on how you proceed.  I'd still worry a bit as the first tests called your SSD's health into question.

Summarizing:

- HD Tune reports Reallocated Events Count = 16. According to some readings I have been doing on the Web this could be normal for a SSD

- WD Data Lifeguard Diagnostic reports a red value for End to End Error Rate, I don't know what this is but as far as i understand its ID should be B8, not B4.

- CrystalDiskInfo reports all values ok

- Crucial Storage Executive reports all values ok (still Reallocated Events = 16 and Read Errors = 47, probably these values are considered normal)

 

I suspect that some of these programs misinterpret S.M.A.R.T. values because they are designed for HDDs not SSDs.

I would consider the Crucial program as the most reliable since it is from the manufacturer of the drive.

 

Tbh I don't know how to proceed, maybe I'll keep using the computer until I get another BSOD.

Tests are just tests.  They give you clues on how to proceed, but I never consider them as 100% accurate.

As the issue seems related to the SSD/HDD, the next test would be to try a new drive (either an SSD or an HDD).

If you don't have one to try, you may want to purchase one from a shop that will accept returns (and give you your money back) if it doesn't fix things.

 

As it's just a test, don't bother to activate the OS on it right away.

Only activate it if you're going to keep the drive and the OS installation.

 

Good luck!

The computer works fine right now so I wouldn't see any difference even with a new drive.

That's the problem with BSOD's - until they appear you don't know if there's a problem or not.

Good luck!
