Looking for merciful soul that would help me analyze few BSOD minidumps :)

I have updated the BIOS, have latest NVIDIA drivers and all works OK even under load testing. But from time to time (1-3h) a BSOD with random message will appear.

System info Windows 7 x64 RTM

AMD Phenom II X4 820
8GB of DDR3 RAM(4 x 2) Kingston
Gainward GTS 250 512MB DDR3
HDD1: Samsung SATA 320GB
HDD2: Samsung SATA 1TB
MOBO: Gigabyte MA770T-UD3P

Memory diagnostic does not show any problems...

You can get the memory dumps (link is dead now)

Any suggestion on how to trouble shoot this further?

UPDATE

WinDbg !analyze:

Probably caused by : ntkrnlmp.exe ( nt!KiInsertTimerTable+13b )

Blame MS? :) I guess Ill start swapping RAM in and out.

More details:

SYSTEM_SERVICE_EXCEPTION (3b)
An exception happened while executing a system service routine.
Arguments: Arg1: 00000000c0000005, Exception code that caused the bugcheck
Arg2: fffff80002c8894b, Address of the exception record for the exception that caused the bugcheck
Arg3: fffff8800b148bc0, Address of the context record for the exception that caused the bugcheck
Arg4: 0000000000000000, zero.

Debugging Details:

EXCEPTION_CODE: (NTSTATUS) 0xc0000005 - The instruction at 0x%08lx referenced memory at 0x%08lx. The memory could not be %s.

UPDATE 2

memtest86+ showed an error with overnight testing - time to swap out the rams :) hopefully its them not the mobo or cpu.

Thank you for your imputs!

pls, specify your BSOD error – MicTech Aug 22 '09 at 16:29
    
Done, I didn't specify it earlier as I was getting a new each time, now it seems I get the SYSTEM_SERVICE_EXCEPTION for last few times. – Kamil Zadora Aug 22 '09 at 16:41

082309-14742-01.dmp indicates that you have faulty hardware:

CONTEXT:  fffff88008876fc0 -- (.cxr 0xfffff88008876fc0)
rax=0000000000000001 rbx=fffffa800953ec20 rcx=0000000000000001
rdx=f7fff880009ea868 rsi=00000000000014e0 rdi=fffff880009e7180
...
nt!KiInsertTimerTable+0x13b:
fffff800`02cd094b 488b42f8        mov     rax,qword ptr [rdx-8] ds:002b:f7fff880`009ea860=????????????????

Note that rdx=f7fff880009ea868. That's a non-canonical x64 kernel mode address. Valid x64 kernel mode addresses range from 0xffff800000000000 to 0xffffffffffffffff. The '7' digit looks like a single bit error. All of the other dumps display the same stuck bit. I'd try swapping out your RAM first and running Memtest86+, but it could be the motherboard or CPU as well.

Also, the crash associated with 082309-24663-01.dmp occurred while executing VirtualBox.exe, but I think that's a red herring. Nonetheless, virtualization software is worth mentioning when posting about a bugcheck.

Thanks, VirtualBox was one of many BSODs :) – Kamil Zadora Aug 22 '09 at 20:19

Yup, after a night of testing with memtest86+ - error found... – Kamil Zadora Aug 23 '09 at 6:15

BlueScreenView from NirSoft might help you determine which files caused the BSOD.

It is compatible with Windows 7 and 64bit.

Load it up in WinDbg, do '!analyze' look for the module with the star next to it and blame them.

The best way to debug this issue is to strip the motherboard down to the minimum components that allow the install, then swap components out one-by-one with known good components which were tested on another system first until the issue goes away. Start from the minimum baseline, then make changes one at a time.

This may not be the most fun way to find the offending component/driver, but it is very effective.

I tried without the second hdd and dvd-drive - all else I can strip are DDR3 modules. – Kamil Zadora Aug 22 '09 at 20:18
