Rebooting, sometimes get BSOD, sometimes not

Your most recent dump file is from early August.
The experts will see what they can do, but look at what they will be working with:
Attachment 232845

While they are perusing your dumps, then

Help us to Help You.

Fully and completely fill out your system specs please.
Update your SevenForums System Specs
User CP (located on the top menu bar) |
Your Profile | Edit System Spec (left-hand column)

To gather info, use Speccy (my favorite) or SIW or System Info

In the System Manufacturer Block, enter:
Ø Manufacturer and Model OR Custom build.
Ø ADD the word laptop, desktop, netbook or tablet.
For example:
Toshiba Satellite L305D notebook.

Provide full windows version info, for example:
MS Windows 7 Ultimate SP1 64-bit

Use the “Other Info” block for Optical Reader,
Mouse, touchpad, wifi adapter, speakers, monitor, etc

Scroll down and click on SAVE CHANGES.

With Speccy, you can select with your mouse/touchpad info from the display
and paste that info into your specs.

SIW is a marvelous program, but the free version does not offer
this capability.

I see you have Malwarebytes : Malwarebytes Anti-Malware removes malware including viruses, spyware, worms and trojans, plus it protects your computer installed already.
Have you run a full scan with it recently to check if you're infected? If not, do the full scan.

There is a possibility that the reason for no recent dumps can be due to certain settings.

work thru this list and make sure that ALL settings are as specified:
MEMORY DUMPS – REQUIREMENTS


CREATE MINIDUMP FOLDER
WIN | type %systemroot% | ENTER
If Minidump is not shown, Then
CTRL + SHIFT + N keycombo |
CONTINUE button | type Minidump | ENTER

Enable automatic management of the Paging file
WIN + PAUSE key combo |
Advanced system settings (left-hand side) |
Advanced tab, Performance section, Settings |
Advanced tab, Virtual Memory section, Change |
checkmark Automatically manage paging file size for all drives |
OK | OK | OK



STARTUP AND RECOVERY SETTINGS
WIN + PAUSE key combo |
Advanced system settings (left-hand side) |
Advanced tab, Startup and Recovery section, Settings |
System Failure section | checkmark Write an Event to the system log
| uncheck Automatically restart |


Under Write debugging information, select Small memory dump |
in the Small dump directory: box, enter %SystemRoot%\Minidump| OK

If Overwrite any existing file is checked, then:
Ø Under Write debugging information, select Kernel memory dump
Ø Uncheck Overwrite any existing file
Ø Under Write debugging information, select Small memory dump
Ø OK button
If you get a crazy message from Win 7 about your paging file being too small, then just ignore the message since we have already made sure that the paging file is set to be managed by Win 7.

ENABLE THE WINDOWS ERROR REPORTING SERVICE
WIN key | type SERVICES.MSC | ENTER |
Scroll down to Windows Error Reporting Service |
Rt-clk on Windows Error Reporting Service | Properties |
General tab | for Startup type, choose Automatic |
In Service status, Start button (unless grayed out) | OK


ASSURE THAT CCLEANER IS NOT DELETING DUMPS
CCLEANER | Cleaner icon | Windows tab | System category |
Uncheck Memory Dumps


WINDOWS ERROR REPORTING SERVICE must NOT be disabled!
· WIN | Services.msc | Enter
· Under Name, locate Windows Error Reporting Service
· If Status is not Started, then
Right-click on Windows Error Reporting Service |choose START
· If Startup Type is not Automatic, then
Right-click on Windows Error Reporting Service |
choose Properties | General tab |
set Startup type to Automatic
· Close Services.msc (I like to use ALT + F4)

After a crash, the minidump file will be in %SystemRoot%\Minidump
%SystemRoot% is generally C:\Windows

Good.

To make sure that the dump file settings are correct,I'd like for you to run a script for me.
