Windows 7: contast BSODs

contast BSODs

Hey there guys, I'm fairly new (oh, this is my first post. I thought i had posted here before!), I'll try to be as specific as possible here, hopefully someone can help!

I've been running various builds of Windows 7, 7000,7100,7137, and now 7229.

7229 was running great for me until a few days ago. I've been getting BSODs on the regular. Sometimes 2 minutes after booting, sometimes it'll go 3-4

hours. It'll happen while playing a flash game, typing something in notepad, playing a fullscreen video.... anything really. no pattern. I've tried

playing a game with networking totally disabled to see if it was iffy network drivers, (i had that issue at first, downloaded new ones from asus), but

still got a bsod. In fact, I'm typing this in notepad, because I'm afraid it'll crash while trying to type this into the web form, and ctrl-S-ing every

30 seconds lol.

But I digress. After checking many forums, including this one, I've tried a few things. the sfc /scannow option reported 3 broken files, chess.dll and

two files relating to windows natural speech. I assume it has something to do with this not being a final build, and in fact have never even used that

service. My BSODs give me errors ranging from IRQ_NOT_LESS_OR_EQUAL to something like WINDOWS_SERVICE_ERROR. Sometimes they point to a (seemingly

random) dll file, sometimes they are flagrant STOP errors pointing to nothing.

I have tested my memory using the windows checker and another one on a boot diagnostics disc i have, memory checks out. I tested the motherboard using

another program (can't remember which, came on hirens boot CD), no errors there. chkdsk came back with a few bad pointers, but that's pretty normal, and

i've still had issues since those got fixed.

Analyzing my minidump files gives me pretty much nothing, since the modules (or whatever they're called) aren't designed for windows 7... it pretty much

just errors out and tells me ntoskrnl.exe is broken. its not. I've checked. Even if it was, that wouldn't allow me to boot, but wouldn't cause BSODs.

Anyway, heres my hardware:

ASUS P5Q SE2 socket 775
Q9600 2.66 quad
corsair 800mhz DDR2 2GBx2 (4 total) (tried at stock 1.7V, and 1.8V, maybe it was 1.8/1.9. either way, tried upping it by .1 volt)
650 watt antec power supply (my 12V reading is a bit iffy at 11.62, but i've always heard 11.5 - 12.5 is more than fine)
ICE-Q Radeon HD4650 1gig RAM (tried with latest, and second latest Windows 7 drivers)

I'm banging my head against the wall. I've tried everything. Any help will be greatly greatly appreciated.

Here's a link to 2 crash dump reports, which provide very little information.

PS: It's not overheating. I couldn't FORCE my cpu temp over 52C, and couldn't FORCE my video card over 60C.

My son's system has an Asus M4A board and crashed BSOD like that with 7232, so he went back to 7100 (we don't jump into every one that comes out). We tried to diag the prob a bit, but it wan't that big a deal, so he went back to 7100, which worked fine for us since it's release. Two other machines here have 7232 and are fine.

It's very difficult to get anything from the unsupported builds. But it is possible.
I can't seem to open the link to where you've stored the minidumps - could you check to see if it's functioning?

The link looks like its still active. I'm sorry if it's not working for you. pastebin.ca occasionally goes down for 10-15 minutes at a time, so that might be it.

My computer is no longer crashing constantly, though I'm not sure what I've done to make it more stable. I've changed so many things, its really hard to tell. I've changed all of my system drivers to the newer Intel ones for the G45 chipset, and that seems to have had mixed effect. My computer seems to "drag" now on basic tasks, such as window and menu redraw rates, and games (Mass Effect) seem to take nearly 3 times as long to load initially, and in-game as well.

Checking my Windows Experience Index still shows me at a 5.9 for HD, and 6's and 7's for everthing else, and Mass Effect still runs at a very smooth framerate, however. I'm not really sure where this bottleneck is, but there are very interesting side effects now.

Examples: CTRL-A in notepad actually shows the entire "blue" selection process. For a maximized window, it'll take about 2 full seconds to redraw. Programs using custom drop-down menus (such as PHPEd) will take a full 2 seconds to draw the menu items after clicking "File" or "Tools" or something of the such. Hitting CTRL-Tab in Firefox gives me a solid 1-2 second delay before redrawing the window. It seems my 2D performance has disappeared entirely. Even if it was software rendered, with a 2.66 QC, it should be faster than that. Yet, Windows gives me a 6.7 in the index for 2D performance. Something is just very wrong here.

I did finally get another blue screen, but after having a game running for 16 hours before it happened, I think I can live with that. (No, I didn't play for 16 hours, I left it running to test it. I only played 8 ;-) )

Thanks in advance for any insight.

There's a lot missing from the dump file(s) that you posted (I finally got into the site to look at them). The headers and excess information often provide clues as to what's going on.

The 1st dump that I saw pointed to dxgmms1.sys which is a Windows file associated w/DirectX. So, it's most likely (in no particular order):
- PSU issue (? - I saw a few of these posts when searching the web)
- video card issue/malfunction
- driver issue (video card or other video programs)
- Windows issue

The second dump didn't tell much, pointing to ntoskrnl.exe trying to use the "Special Pool".

Could you zip up the latest dump file and then upload the .zip file in your next post? Maybe an indepth look at the analysis will reveal something we're not thinking of.

Your PSU likely has enough power to run the rig, unless there's something wrong with it (I don't know of any tests for it).

Your video card may have problems, I've seen systems overheat even though the temps were good (it was an nVidia 250 card). Pointing an 80 mm fan at the card stopped the crashing - so that's the diagnostic test for thst.

Windows? Well, it's an unofficial build and as JeeperDon has stated, he experienced some similar issues. Dunno if it's exactly the same issue, but it's a possiblity.

Finally drivers...Try running Driver Verifier using the instructions that follow. Please read the directions completely before trying it, as it can render your system unbootable:
Quote:
Using Driver Verifier is an iffy proposition. Most times it'll crash and it'll tell you what the driver is. But sometimes it'll crash and won't tell you the driver. Other times it'll crash before you can log in to Windows. If you can't get to Safe Mode, then you'll have to resort to offline editing of the registry to disable Driver Verifier.


So, I'd suggest that you first backup your stuff and then make sure you've got access to another computer so you can contact us if problems arise. Then make a System Restore point (so you can restore the system using the Vista Startup Repair feature).


Then, here's the procedure:
- Go to Start and type in "verifier" (without the quotes) and press Enter
- Select "Create custom settings (for code developers)" and click "Next"
- Select "Select individual settings from a full list" and click "Next"
- Select everything EXCEPT FOR "Low Resource Simulation" and click "Next"
- Select "Automatically select unsigned drivers" and click "Next"



If no drivers show up, then select "Select driver names from a list" and click "Next"
Then select all drivers NOT provided by Microsoft and click "Next"



- Select "Finish" on the next page.


Reboot the system and wait for it to crash to the Blue Screen.

Reboot into Windows, turn off Driver Verifier by going back in and selecting "Delete existing settings" on the first page, then locate and zip up the memory dump file and upload it with your next post.


If you can't get into Windows because it crashes too soon, try it in Safe Mode.
If you can't get into Safe Mode, try using System Restore from your installation DVD to set the system back to the previous restore point that you created.
If that doesn't work, post back and we'll have to see about fixing the registry entry off-line.

Thanks usasma. I had read about verifier elsewhere, but never really understood how it worked. I'll give that a shot now that i have good instructions.

Once thing I did notice while checking off the drivers (it didn't find any on its own), is that two of the Microsoft drivers still had the 7127 build number tagged on them: spldr.sys and spsys.sys. They appear to both be related to low-level security... maybe bitlocker files? I don't know, Google turned up only cryptic answers related to them, but I thought it might be worth noting.

I've also since reverted all of the motherboard drivers to the Microsoft ones. In the process, I noticed that in safe mode, my 2D performance is super-fast, but I still get "laggy" response on everything when not in safe mode. I've also tried 3 versions of my video driver, just to be sure. (2 WHQL certified ATI drivers, and the standard driver included with the Windows 7 install).

The dump files all point to different files, actually. I've rarely seen the same file come up twice on my blue screens. I've seen everything from USB drivers, to ATI drivers, to DirectX drivers to AHCI drivers, to ACPI drivers... everything under the sun. Never the same memory pointers either.

The power supply is sufficient, I'm sure of it. If I had a 65mm core or dual graphics cards, I might suspect it, but I only have one hard drive as well, and I even tried it unplugging my DVD drive and extra (5) case fans, with nearly identical behavior.

The graphics card is not overheating, i've seen it crash with GPU-Z showing very low temparatures, and I do have 2 80mm fans on it besides the monster ICE-Q fan that comes standard... plus my giant CPU fan is designed to get extra airflow on surrounding components.

My first line of troubleshooting would be to upgrade to the 7332 build, even though little has changed, but last time I tried that, it blue screened on me while it was gathering all the install files, and just left me with 3 gig of junk on my C drive.

Oops.

Here is a link to some recent dumpfiles. The 6 files in the folder are all included in the zip file.

Don't worry about Windows files (especially in unofficial builds) - unless there's indications that this isn't the real thing (such as a hacked version rather than a leaked build).

I suspect a hardware issue here - but it's only a guess on my part. Either compatibility issues, or an actual hardware problem. BSOD's all over the place are usually indicative of it - especially if it's a low level incompatibility such as video, chipset, or storage drivers (I've got this issue with my RAID card).

Let's see what Driver Verifier tells us before moving on to other things.

Well, I still had my Vista installation active on another partition, and the 2d slowdown was too hindering to deal with... I build websites... Super-slow text editors makes my computer useless, and Vista ran great for me, I rebooted once every 2 weeks or so on average.

So, I'm back to Vista, and I'll let Windows 7 sit, unused, until I have a full day to just nuke and start from scratch with it. I might even just wait until RTM. I didn't get a bluescreen for a full 24 hours (of course), but still had the slow 2d issue.

In the meantime, if those minidump files offer any insight, I'd love to go back to the super-fast, super-great Windows 7 if i can salvage the install.

Thanks for the help!

Well, this might help with the slowdown - Intel chipset users seemed ot have run into a snag with eralier builds regarding HD access times - it seems that HDs went extremely slowly after a while for both nVidia chipset based machines as well as Intel based machines - you can read the entire thread, but I'll link you to my contribution of it - short story is to uninstall those Intel drivers one by one and see which actually affects your HD performance.

Show Us Your WEI

I never was able to figure out a solution for Intel Chipset-based machines as I don't have one here to play with....
