Random Windows 7 BSOD's - Pls help

post #1 of 6
Thread Starter 
Hi,

Please help with my problem as I am running out of ideas and a bit (well, quite) desperate by now. So, a few weeks ago I built a new computer for my wife from parts. And I am keep getting (seemingly) random BSOD's. So far I put together more than a dozen computers during the last ten or so years but I never had this problem before (maybe I was lucky?). First, the system specs:

- Zalman Z9 case with 5x120mm fans and with a Alpine 650W Quiet PSU
- Gigabyte H55M-USB3 mother board (on-board LAN and sound used, on-board graphics disabled - everything with newest driver)
- Intel I3 550 (not overclocked) with Akasa 2x3 pipes cooler
- XFX Radeon HD 5850 Black Edition video card (with newest driver)
- 2x2GB Corsair Vengeance DDR3 1600MHz PC3-12800 memory
- 2x 1TB 7200rpm HDD (SATA-2, in AHCI mode)
- Samsung WriteMaster optical drive (with newest driver)
- PS/2 keyboard, USB optical mouse
- Microsoft LiveChat USB Headset
- Windows 7 Home Premium 64-bit, Windows Update On, fully up-to-date
- Comodo free firewall (Windows firewall disabled) and Microsoft Security Essentials
- Opera, Firefox, Internet Explorer 64bit, SKype (all newest versions)
- TotalCommander 7.5
- LibreOffice (newest)
- VLC media player, BlazeDVD, Movie Maker
- Sims 3 with all expansion packs (my wife's favourite)

That's it. The problems with the BSOD's:
1) That they happen only once in every 6-10 hours and I can't reproduce them, they seem to be random (one happened when browsing internet, one when tried to open a folder, one when nobody used the computer and screensaver was on, one when my wife played a game on the computer etc.). So I the "uninstall/refres/etc. something and see if it works"-method does not really work as I would need three days of continuous computer use without a BSOD before I could say the problem is solved...
2) Moreover, I cannot find the memory.dmp file! I turned on visibility of hidden and system files, tried to locate it manually, run a search for it on entire drive C and - nothing! BUT, on the BSOD screen I can see the percentages going up as it is saving it. Yet, the file is nowhere. I checked the system settings, it should be in System Root, named as memory.dmp. Not there...
3) And to make it even harder, the BSOD screen is different each time. Sometimes it just says that it had to be done to prevent damage to the computer. Sometimes it says "BAD_POOL-HEADER". Sometimes it say that a driver is incorrect and that I should run Windows Driver Verifier. Etc...

So I would say, random BSOD's, at random times, at random operations (or
even when system is idle). It can be any driver, firewall, BIOS (did not update it yet, it is pretty recent already!) etc. etc.

There is one more "interesting" thing as well, namely, that at random times and at random operations (approx. once in every half an hour on average) the application my wife uses (it can be anything, Firefox, LibreOffice, TotalCommander, and even Notepad!) stops responding completely for approx 12-15 seconds (other applications run well/normally in the meantime). Sometimes (but not always) the entire application window "greys out" (but this does not affect any other application). And, even more "interestingly" whenever this happens the HDD LED is solid on, as if it was doing some file copying or whatever. But what could Firefox or Notepad copy (or do, whatever) for 12-15 seconds so intensively that the application stops responding?? But (seemingly) there is no connection between this and the BSOD's, i.e. no BSOD ever happened during these interesting 12-15 seconds, nor immediately before or after.

The system is stable, I pressed it with Orthos and other similar applications, no processor error. Did two different memory tests too (one being Windows's own test), no error. The temperatures are very low, 25-40°C (CPU, memory, HDDs, Video), no problem with that. Drivers were all okay. The only thing was the mobo's LAN driver, Windows 7 did not sensed the attached LAN cable for some reason, so I downloaded the newest one, Internet access is great since that.

So, I have no idea. To change something and the wait to "let's see", takes a day each time. Memory dump file is missing. Strange 12-15 seconds of HDD led on periods with application not responding. Blue screen death in every 6-10 hours. All seems as random as possible. Have no idea... Probably I would uninstall Comodo now, turn Windows Firewall back, use the computer for another 10-12 hours and hope it was the Comodo... (If I google "application name + BSOD" I get hits for everything, so it can be anything...)

There must be a way to solve this problem. I spent a lot of money and time on this computer, and yet it produces these BSOD's that never any of my computers did...

Please help. Any idea is welcome.

Thanks,
Attila

Oh, I did not run Windows Driver Verifier yet, because
A) I am not (yet) sure how to do that
B) http://www.sevenforums.com/drivers/5...-verifier.html I read quite a number of posts like this saying the Driver Verified junked the whole system. (Shouldn't it just verify - why does it change things?)

Oh, just one more thing, Comodo and MSE was installed as soon as I had the internet connection, never went online without them, and we did not visit any suspicious/"dodgy" website (visited only sites that we have been visiting for months or even year), so I would not suspect any virus or similar pesky thing. (Unless something came through Comodo and MSE from the websites we know...)

Thank you. I ran it. Nothing. All empty. It says "0 crashes"...

I have just set AlwaysKeepMemoryDump in Registry. Maybe now it will save the dump file.
