Windows 7: System Randomly Shuts Off - Since Yesterday [Problem Details Within]

28 Aug 2012   #21

MS Windows 7 Ultimate SP1 64-bit

Your last chkdsk came up clean.

do you only have one partition?

I am still concerned that the hard disk program hung on you.

I need you to run another script so that I can get a better feel for your system. If I wasn't so lazy, I could dig thru all of the files in a file. I find this handier

WIN key | type POWERSHELL | do NOT hit ENTER |
in the PROGRAMS list, right-click on WINDOWS POWERSHELL |
choose "Run as administrator" |
Click on the YES button (if such appears)

COPY the script using CTRL+C,
PASTE into Powershell
---Right-Click at the PowerShell Prompt
---(Ctrl+V does not work)

WIN key = key with Microsoft logo on top

The script will put MySystem.txt on the desktop. Attach to your next post please.

Yeah I was too at the time, the reason I started running dskchks was cause an issue with the HDD was something I'd overlooked, that combined with the fact I'd recently ran Windows Performance and Resource monitor and it flagged up the HDD with a warning - nothing bad though - this has since disappeared and now my system performs great in the health report.

I just have the one partition on C: with the usual 100MB system reserved space.

Here are the results of the script:

Your mobo was excellent when released. There has not been a bios update since 2009 ( you have the latest). there has been an update for the chipset & network. You might want to visit the evga site and see regarding the chipset/network driver.

Did that 2+2+1+1 memory combo come new? Are all of the modules on the memory compatibility list for your computer?

I going to recommend a memory test.

RAM - Test with Memtest86+

Have you ever taken the cover off and blown out all of the dust inside with a can of compressed air? Do NOT use a vacuum cleaner.

I am currently using the latest Chipset & Network Driver (15.58 WHQL) which is listed on both EVGA and nVidia's driver pages. I've been using that driver ever since I installed my current OS. I'm quite aware it's good practise to keep up to date with drivers and software

In regards to the 2+2+1+1 memory combo:
The 2+2 modules were bought new.
The 1+1 modules were given to me from my brothers build who happened to have them laying around as spare - coincidentally they are the exact same make and model of the 2+2 I already had in use (except these are 1GB versions) or I wouldn't be using them all together.

Not sure if the exact model is on the compatible list for my Motherboard but I can assure you that they're set to the correct speed/timings and Voltages under my BIOS settings and I've had this system issue free for years up until now!

I blew some dust out with some compressed air when I started this thread, I tend to dust it out every once in a while to prevent heat inducing/fan slowing dust build up.

I've troubleshooted plenty of issues with family and friends computers but for the first time ever I can't for the life of me work out why my own system is shutting off when it pleases!

I'll set Memtest86+ to run over night soon. I've used that same software in the past to diagnose a faulty motherboard which used the same RAM as I'm currently using today. The last time I scanned my current system with Memtest86+, the modules all passed fine - let's see if they can do it again - I secretly hope they don't so we'll of worked out what this damn issue is!

Just starting my day. Will be back to you in about 2 hours.

Glad to hear that memory passed.

you did test all memory sticks, correct?

Since your file did not include any .dmp files, I would like for you to go thru this carefully.

As true is that not all freezes and crashes generate dmp files, but an amazing number do.


Enable automatic management of the Paging file
WIN + PAUSE/BREAK 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

WIN + PAUSE/BREAK key combo |
Advanced system settings (left-hand side) |
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:
Under Write debugging information, select Kernel memory dump
Uncheck Overwrite any existing file
Under Write debugging information, select Small memory dump
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.

Scroll down to Windows Error Reporting Service |
Rt-clk on Windows Error Reporting Service | Properties |
tab | for Startup type, choose Automatic |
In Service status, Start button (unless grayed out) | OK

CCLEANER | Cleaner icon | Windows tab | System category |
Uncheck Memory Dumps
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
