Hi technet, I hope this is in the right place, I wasn't quite sure where to post this. :) My problem: Over the past five months or so a computer belonging to one of my family members has had a number of blue screens of death. It's a pretty infrequent occurrence, almost always while browsing the web in Mozilla Firefox, but it also blue screened shortly after startup when Firefox wasn't open on one occasion. I have the system configured to do a full memory dump when it crashes, so that's basically what I'm looking for, someone who knows what they're looking at to analyze the dump and help me identify the source of the problem. I uploaded the dump from the latest BSOD here. Specifications Windows 7 Home Premium 64-bit Gigabyte H55M-D2H mobo Intel Core i5 661 CPU 4GB Apacer DDR3 RAM ATI Radeon HD 5770 graphics card 1TB Seagate HDD DVD reader/writer Security applications in use Windows Firewall Avast! Anti-virus Spybot Search & Destroy These same programs are used by two other very similar systems (also 64-bit Windows 7) in the household, neither of which have had blue screens. Bluescreens Oct 31: Blue screen on startup. Error code: 0x0000003b Nov 19: Blue screen shortly after startup, while opening Firefox. Avast antivirus was updating at the time, too, because it complained that it had been interrupted when Windows booted up again. Error code: 0x00000024 Nov 19: A second blue screen happened a few hours later on the same day. Again, while opening Firefox. Error code: 0x00000019 Brief tangent; I looked the above two error codes up that day. Both seemed to be related to the file system, so I did a full disk check and hoped that would be the end of it. For some time that seemed to be the case, until... Dec 15: Blue screen while using Firefox. The most recent one, and the source of the memory dump I linked above. Error code 0x0000003b Note: I don't know if it's related, but when I looked in the event log to find out which error code the BSOD gave, I noticed there was another error just a couple of minutes before the BSOD, which may or may not be related. Here's a screenshot of it. Thanks in advance for any assistance!

Bug Check 0x3B: SYSTEM_SERVICE_EXCEPTION This indicates that an exception happened while executing a routine that transitions from non-privileged code to privileged code. http://msdn.microsoft.com/en-us/library/ff558949%28VS.85%29.aspx STACK_TEXT: nt!CmpKcbCacheLookup+0x1dd nt!CmpBuildHashStackAndLookupCache+0x328 nt!CmpParseKey+0x2a1 nt!ObpLookupObjectName+0x585 nt!ObOpenObjectByName+0x1cd nt!CmOpenKey+0x28a nt!NtOpenKeyEx +0xf NTOpenKey opens a registry key. So you have an issue with the HDD/Registry. The 0x24 bug check shows NTFS issues. So you should check your HDD with a diagnostic tool from your HDD manufacture and run chkdsk /r /f to fix NTFs file system issues. best regards André"A programmer is just a tool which converts caffeine into code" CLIP- Stellvertreter http://www.winvistaside.de/

Hi Andre! Thank you kindly for the prompt response. I ran a checkdisk as you suggested. A day or so later another blue screen took place, again with the error code 0x3b. I uploaded the memory dump from this crash here . I then downloaded Seagate's drive diagnostic utility "SeaTools" and ran all of the basic tests (S.M.A.R.T. test, short and long self tests, short and long generic tests). Every test passed, so I'm not sure how to proceed.

You have a new crash: STACK_TEXT: nt!ExFreePool WithTag+0x72b win32k!EngRealizeBrush +0x241 win32k!bGetRealizedBrush+0xae4 win32k!pvGetEngRbrush+0x25 win32k!EngBitBlt+0x5a6 win32k!GrePatBltLockedDC+0x2f9 win32k!NtGdiPatBlt+0x2c9 nt!KiSystemServiceCopyEnd+0x13 the PC crashes while Windows tries to free some used memory which was used to draw a Brush [1].

I updated the display drivers yesterday, but this morning it blue screened again (while looking at a web page in Firefox), and when I went to Google the error code (0x0000001a ), Firefox opened the tabs it had open before the crash, and it promptly blue screened again, this time with 0x0000003b . Here's the memory dump from the latter crash. I'm really starting to get discouraged. If there's anything more you can do to help I'd appreciate it. :(

Which RAM do you use? Run CPU-Z and post screenshots of the memory and SPD tab."A programmer is just a tool which converts caffeine into code" CLIP- Stellvertreter http://www.winvistaside.de/

Sorry for the long delay, some other things (not related to computers) came up that made this seem unimportant by comparison, but that's all cleared up now and I'm still trying to fix this problem. This is a memory dump from the most recent crash, which took place today while the computer was idling. Error code 0x00000024 Link Side note: Is it okay if I archive any future memory dumps I might upload with 7zip (.7z file ext)? They're about half the size that way. And here are the screenshots from CPU-Z. http://i.imgur.com/XyKYx.jpg http://i.imgur.com/IAmsX.jpg http://i.imgur.com/0d0n6.jpg Thanks for your patience. :)

ok, you run the RAM with Command Rate of 1T, this is too aggressive for most RAMs. So, enter the BIOS and change the Command Rate (CR) to 2. The latest crash shows Bug Check 0x24: NTFS_FILE_SYSTEM - This indicates a problem occurred in ntfs.sys , the driver file that allows the system to read and write to NTFS drives. Windows crashes while creating a file, so you should also run chkdsk to detect and fix NTFS issues."A programmer is just a tool which converts caffeine into code" CLIP- Stellvertreter http://www.winvistaside.de/

Okay, I changed the command rate to 2 and am running a chkdsk now. I'll let you know how it goes. Thanks for the prompt reply! :)

The computer has been in daily use since the change I mentioned above. Unfortunately, it has bluescreened once more, one week ago. The code from this latest crash is 3b. Here's the memory dump (it's in a 7Zip archive to save space, hope that's okay). Do you have any more ideas?

Will do, thanks. :)

Hi again! I was getting pretty confident that the problem was fixed as the computer went for a couple of months of daily use without any more problems, but it has now blue screened one more time. The crash took place while Mozilla Firefox was being opened (once again), and the error code was 0x00000019. I've uploaded the memory dump here and I'm hoping you can look at it and give me a hint as to what caused it. Thanks!
