Windows 7: Windows Unexpected Shutdown

Windows Unexpected Shutdown

Hi everyone; mind you that this is my first post and I'm pretty well computer-oriented but unfamiliar with Windows 7 (its a pretty different from XP).

I keep getting unexpected shutdowns from my system when I leave it idle and its happening faster and faster. It started with when I leave it at night (even though its set for auto-standby after an hour) and now its after maybe 30 minutes. I've never seen it happen but I come back to my computer shutdown constantly.
I found a similiar thread but its not specific to my system and didn't help much further than recognizing it as a related issue (but is probably totally different).
But here's the real details:

I turn on my PC and get a random message (every time) that security has been shut off, but its just an error message with no details of what files or programs are associated; which leads me to think I may just have a Windows 7 virus (I have scanned with ESET NOD32 and found nothing on either of my two main HDDs yet my PC is funkedelically shutting down and acting slowly).

Here is the windows error details:

From what I understood in the thread I found that lead me to this forum; some of my hardware is faulty/glitching/failing. I think it may be my RAM because there was a mention of a file with "RAMdump" in the name, so maybe at idle the RAM gets overactive and the system failsafes and shuts down? --Mind you I built this PC at Christmas time and only slightly skimped on prices for my PSU (though it was a budget build), my RAM was $105 for 4GB and I specifically bought RAM that is under the 1.6V limit of the i5 CPU.

System specs:

-Intel Core i5 750 (2.67GHz) CPU
-Intel P55 MoBo
-Windows 7 Professional 32bit
-XFX GeForce 250GTS GFXcard
-Apevia ATX-JV650W PSU
-Seagate Barracuda 320GB 7200RPM (exclusively OS and programs)
-Seagate Barracuda 750GB 7200RPM (data)
-G.Skill (2 x)4GB DDR3 1600MHz Dual Channel RAM


I'm trying to be as thorough as I can, sorry for a lengthly read...the only other thing of note is that I have a Sound Blaster Audigy sound card and I didn't take any precautions to disable the onboard sound card/settings.

Thanks for any help I can get with this mysterious hardware failure (or whatever it may be).
-Edward
PS: Mind you that my PC was running find for over two months and starting doing this about two weeks ago.

Lets check the important things first and move on from there.

Run an anti virus scan.

Then download and run malwarebytes.

Once you are sure there are no nasties, run is safe mode. If that works we will do a clean boot to find the cause.

Hello JezusSaurusRex, welcome to Seven Forums!



As you mention the RAM, here is a good, free app to test the RAM, download it and burn it to a CD and boot to the disk and do at least a couple passes to see if you get any errors.


Memtest86.com - Memory Diagnostic

Be sure to post back after you find something out.

Usually, a bad or failing PSU just crashes the system. no BSOD. Causes a game to exit to Windows etc.

BSODs typically tends to be hardware or driver issues.

I would however, upgrade that PSU to a better one as soon as you can.
The Apevia in't a very good PSU, especially for your build.
4 rails @ 13Amps each. Unfortunately, you cant just add them up for a total of 52Amps. It just doesnt work that way as its splitting the Work load into smaller values.


it could possibly be a PSU issue, But, first thing I would do is try to check if the RAM is good.

Download MEMTEST86+ here:
Memtest86+ - Advanced Memory Diagnostic Tool
burn the ISO to CD or put it on a USB Drive whicever you prefer, and run it.

this should tell you if theres a RAm problem.

Also check the drives for corruption:
open CMD prompt as Admin and execute the cmd :

sfc /scannow

Let us now what the results are.

Thanks for the warm & informative welcome guys.

Malwarebytes caught an open command line in a file and when I clicked the suggestion it removed it and my computer shut down and gave me a BSOD...here's the screenshot I took before shutdown:



And the same weird security error (my basic reaction in the background every time I see this error message):




As for cmd sfc /scannow, it didn't find any errors.

I'm going to run the other memory test but I have to boot from it, I'll update this post when I see the results.
Thanks,
Edward

Well I burned the iso of the memory tester to a CD-R both as suggested by Windows 7 as to be used as a USB and to be used in only a CD/DVD player. Neither disc would boot at startup...so I went into bios and changed the boot order and still couldn't get either disc to start instead of the OS. I also put a boot latency on the HDDs and that did nothing. So now I'm stepping back and scratching my head on how well I can actually use Windows 7.

Something of note:
When I rebooted, every time I would get a BSOD right when the "Windows is shutting down..." screen came up and it would dump the physical memory by failsafe and shutdown.

Sounds like a ram problem or is this not enough information to prove it? I'm on the fence of it being a virus and memory problem.
Any suggestions? How can I properly run the memory tester?
Thanks again,
Edward

Is there any chance a program / app you've recently installed is hanging at shutdown, have you installed anything recently?

In the last month I installed Uniblue Registry editor...could it have #%&*ed my files? It made a backup of my registry...and now that I think of it, Malwarebytes found a registry error and crashed when it repaired it.

I recorded the crash with my camera and paused at the BSOD and found this:
Quote:
A problem has been detected and windows has been shut down to prevent damage to your computer.

If this is the first time you've...blablabla...

Technical information:
Stop: 0x0000007E (0xC000005, 0x95E5529C, 0xA12C0B40, 0xA12C0720)
usbhub.sys - address 95E5119C base at 95E3E000, DataStamp 4a5bc8a6

Collecting data for crash dump ...
Intitializing disk for crash dump...
Beginning dump of physical memory.
Dumping physical memory to disk:
etc.
The numbers aren't totally right but--well now that I wasted all that time typing it out, I got a screenshot of the video of the screen...I don't think that sounds like a waste of time.



Any help?
