Multiple BSOD daily - Unexpected store exception; critical process died


New Member
Hi everyone,

After a few windows updates i keep getting a BSOD with errors: UNEXPECTED_STORE_EXCEPTION (most of the time) and
CRITICAL_PROCESS_DIED (couple of times).
I tryed to solve it by updating drivers, with restorehealt and also by reinstailling windows but without success.
I ran the run the W7F Diagnostic Tool (result in the attached zip), hoping that someone could help me fix this situation.

Thanks for your time

I only just seen your post so apologies for not answering sooner.

Unfortunately your zip file contained no dump files.

There could be a number of reasons for this but first please check your settings are correct:

Open the run application.

Type sysdm.cpl in the run box and click ok.

Look across the top of the system properties box for 'Advanced' and click that.

Look for 'Startup and Recovery' near the bottom and click 'settings'.

Near the bottom you'll see a drop down menu under the heading 'write debugging information'.

In the drop down menu choose ' small memory dump (256KB)'

Under 'small dump directory' make sure it says %SystemRoot%\Minidump.

Click ok and your good to go

You will of course need to blue screen before a dump file is created.

Other reasons for no dump file can be:

No Pagefile.
The system needs a pagefile in order to create dump files although some SSD users turn it off thinking it's not needed.
If you did this please recreate the pagefile using the recommended amount.

Lastly if your HDD is faulty then this can stop dump file creation too.

try running a chkdsk /r command in an admin command prompt box.

Probably caused by : hardware_disk

this dump file is saying that the HDD was missing at the time of the crash:

ERROR_CODE: (NTSTATUS) 0xc0000006 - The instruction at 0x%p referenced memory at 0x%p. The required data was not placed into memory because of an I/O error status of 0x%x.
Looking at the I/O error we see:

IO_ERROR: (NTSTATUS) 0xc00000c0 - This device does not exist.
This could be happening for a number of reasons like a driver issue or the HDD being faulty. However, I checked your system support page for relevant drivers and noticed this bios update:

BIOS 402 2013/12/12 2.04 MBytes
Fix HDD lost when aging

Your current bios version is:

BiosVersion = X555LPB.301
SystemManufacturer = ASUSTeK COMPUTER INC.
SystemProductName = X555LPB
X550LB Driver & Tools | Laptops | ASUS Global

If you have never updated the bios before you could always take it (the laptop) to a Tec or the local computer shop.

You run a test yourself which will check for and repair broken sectors on the HDD. You need to open an admin command prompt (find command prompt in the start menu, right click on it and run as admin). Type (or copy and paste):

chkdsk /r

The scan works before the system boots into windows so you'll need to reboot when prompted.

Have you recently installed any drivers from sources other than your support page?

Laptops should only use drivers supplied by the manufacturer (apart from some gpu drivers) otherwise it can lead to issues.

If your support page doesn't have drivers for certain components when using Windows 10 it's probably because win 10 already carries the driver in which case don't install anything.

Post any new dump files
