Windows 7 Any idea why my Windows 7 keeps crashing, randomly, kernel-power?

[Invertalon]

Hello,

I have been scanning the internet for a while now trying to solve my W7 crashing issue... I have updated all my drivers, BIOS, and whatever else I possibly could. I don't know what to do from here.

It crashes at random times, with no rhyme or reason. It does it every few days, or every few hours depending on what I do... Which is usually have AIM, Itunes, Photoshop, and Firefox going. I get the Blue screen with a memory dump prior to it shutting down and rebooting.

For example, nothing was running but Itunes and Windows Defender right now, and it crashed. Here are the errors it shows...


Critical Error: Kernel Power - Event ID 41 - Task (63)

The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.

This is the same error and crash I get, routinely. I noticed many others have this same issue, and curious if Windows is working on getting this figured out? It is getting old. My computer was perfectly stable on XP, overclocked, etc... I am running completely stock, with no adjustments anywhere.

Running Windows 7 64x Professional - Nvidea 8800GT - Intel E6750 Core 2 Duo - Gigabyte GA-P35-DS3L (R2) - 8GB Mushkin 1066 Ram

I have tried updating audio drivers, video drivers, monitor drivers, HD drivers, motherboard versions, printer drivers, everything and anything. Nothing seems to work.

So help me out here guys...

Thanks

I only show one audio device, and it is up to date.

So sadly, that doesn't work

Perhaps, if you could, zip and attach, maybe your two most recent .dmp files I could take a look and see if anything more specific is mentioned in them.

System spontaneously reboots, Kernel-Power, Event ID 41, Task Category (63)

Attached are my last two dump files...

Thanks for the help.

This is gonna sound a little strange, but try disabling windows defender for a while and see if that makes any difference. If not you're probably going to need to do some memory diagnostics. If as you say, you're not overclocking, and you have made sure that system temps are well within acceptable parameters. The memory dumps themselves were not individually definitive
from the first one
IRQL_NOT_LESS_OR_EQUAL (a)
An attempt was made to access a pageable (or completely invalid) address at an
interrupt request level (IRQL) that is too high. This is usually caused by drivers using improper addresses.
If a kernel debugger is available get the stack backtrace.
Arguments:
Arg1: fffffa80337eaabb, memory referenced
Arg2: 0000000000000002, IRQL
Arg3: 0000000000000000, bitfield :
bit 0 : value 0 = read operation, 1 = write operation
bit 3 : value 0 = not an execute operation, 1 = execute operation (only on chips which support this level of status)
Arg4: fffff80002ca4065, address which referenced memory
CUSTOMER_CRASH_COUNT: 1
DEFAULT_BUCKET_ID: VISTA_DRIVER_FAULT
BUGCHECK_STR: 0xA
PROCESS_NAME: MsMpEng.exe
from the second one
BugCheck DE, {2, fffff8a01063fae0, fffff8a00c63fae1, 5d77a8c0}
Probably caused by : ntkrnlmp.exe ( nt! ?? ::FNODOBFM::`string'+2d2e0 )
POOL_CORRUPTION_IN_FILE_AREA (de)
A driver corrupted pool memory used for holding pages destined for disk.
This was discovered by the memory manager when dereferencing the file.
Arguments:
Arg1: 0000000000000002
Arg2: fffff8a01063fae0
Arg3: fffff8a00c63fae1

BUGCHECK_STR: 0xDE
PROCESS_NAME: MsMpEng.exe
After checking a lot of information on the net with even more information from the debug files then I provided above, it seems that as in a lot of these cases the actual problems can come from anything from heat, to bad memory, to leaking capacitors on the MoBo, to conflicting software causing problems with device drivers. I don't know if it was just coincedence that Defender happened to be doing its' thing when these two blue screens happened or if there is another antivirus / malware program competing with it and causing this issue. Sorry I couldn't be more help.

Interesting... I will try disabling defender and see how everything turns out. I will report back to you tomorrow with any new dumps, if any. But it seems like Defender acts strange on my computer... And it almost always locks up when I try to use it. So this could be the reason, I will give it a try.

Thanks

I've been having a similar problem since I installed Win 7 Home Premium 32 bit back in October. For no apparent reason, the screen will go black and the computer reboots itself. This was happening completely randomly, and I was getting completely sick of it and ready to ditch Windows 7. However, after much trial and error and reading of these forums, I do seem to have improved on the situation and the last crash of this type I had was 7th January.

The first thing I did was to find some redundant sound drivers in Device Manager and get rid of them. This helped a little bit. I installed all the latest drivers for everything that I could find, but there was no improvement. I then bought new memory, which made no difference. Windows Event Viewer didn't give me much of a clue as I am not knowledgeable enough to understand what it was saying, but in the end I downloaded BlueScreenView which gave me a better idea of what was causing the crashes.

I have two types of crash, the 'black screen/reboot' type and the traditional BSOD, which sometimes occurs when I am using my TV card, but that doesn't worry me too much as I don't use it a lot; the one that was really bothering me was the frequent 'black screen/reboot' crash. BlueScreen View always tells me that it was caused by an Unexpected Kernel Mode Trap and involves atikmdag.sys. A lot of searching showed that atikmdag.sys causes a lot of problems in Vista and Win7 for many people, and there seems to be no definitive answer. Anyway, I tried disabling Aero and this helped a bit with a few less crashes. After a while I noticed BlueScreenView occasionally named a driver called snp2sxp.sys, which it said was my USB2 camera driver. I had been keeping my webcam plugged in, but after I saw this I disabled the driver and unplugged the camera, and since doing this I haven't had any more problems. Until, that is, I switched Aero back on and the crashes restarted. Disabled Aero again, and everything has been OK since 7th January (fingers crossed!).

I'm relieved that the random reboots seem to have stopped, but I still don't fully trust my system, and I would love to get Aero on again, but I don't want to risk it at the moment. I don't know if my experience might be of any help to anyone. Hope so.

My specs are:

Asrock ALive SATA2 GLAN motherboard
AMD64 x 2 6000+
Radeon Sapphire 4670 512Mb
2GB DDR2
Win Home Premium 32 bit
AVG ver 9.0
Windows 7 firewall

Thank you for your input... I will give that a try next.

I ran Prime 95 Stress Test for several (5) hours and no problems detected... UNTIL at the very end, I started itunes just for giggles and it ended up showing some failure along the way.

I then ran the extended memory test through windows and it gave back no memory errors.

Windows defender did not stop my issue by disabling it.

So next up, I will try disabling Aero and see how that goes for me, and get the blue screen viewer.

Thanks everyone, I will get back to you.

Results:

It found their were currupt files but unable to fix them. I attached the CBS Log.



Also, I did get blue screen viewer, but little idea on what to look for... If somebody could lead me in the right direction I would appreciate it!

 

[Invertalon]

A little update...

Decided to swap memory sticks around and remove half of them, and it turns out my problem was in the memory after all. Took out two sticks and have not had a BSOD since, and now I can overclock again. Before, it would not allow me to do ANY changes and boot.

Funny thing is, this was our second replacement pair of this ram. I wonder if the motherboard memory ports going bad? Is that possible or is the ram just that bad?

This was the mushkin enhanced ram, blackline... I was running 4x2GB sticks.

Well for now, it looks to be healed. Thanks for the help everyone. Sorry I didn't do this earlier, but I swear I did and still had the issue.
