BSOD - EVENT 41 after CPU upgrade

[biosol]

I had a stable system Win7 64 bit (with the specs in my profile/sig) with a E6750 (actually 2 months ago the system was about 2.5 years old and the psu, motherboard, and video card were all problematic, so I replaced all of them and got (more) new RAM at that time. I put my E6750 into the new MB and it was stable for 2 months). Wanting more multitasking power, last week I got a Q9550 and swapped out the cpus. It seemed to run fine for a day or two, but over the last 3 or so days has BSOD and various programs like media center have crashed. It have a 2250 TV tuner card, so I reseated it, and yesterday I reinstalled Win7 64-bit so this is now a fresh install. It's BSOD 3 times today. I ran the Sandra burn-in test on it a couple days ago and the cpu and RAM passed the tests, the HDD(s) and DVD failed I think it said they needed to be empty.

I've reset the MB setting to "load fail safe defaults". Please help me discover what's wrong. Attached is are my files.

Thanks.

All 3 dumps seem to be memory related. If you haven't already done so, run memtest86+ (overnight preferably).

http://www.memtest.org/download/4.00/memtest86+-4.00.iso.zip

Burn it to CD using imgburn or similar and boot off the disc.

Good luck!

Get a program called core temp and check to see how hot your cpu is running...sound like your fan might not be properly seated with your new cpu.

 

[biosol]

Ok, got core temp. Just started the system up. Cores 0 & 1 are 36c with 0-2% load, Cores 2 & 3 are 43c. Does that mean anything? What should I run to test out temps?

 

[Mayotruck]

prime 95

makke sure you dont hit the TJmax in core temp when running prime.. it will fry your cpu...keep it 20% lower than the max

whats your current tj max?

 

[biosol]

Tj. Max is 100c. Where do I get prime95 from? I didn't get many/any BSOD for the last 2 months with the same memory, so if the dump indicates memory could the cpu heating up cause it to look like a memory problem?

Also, during Sandra the other day, it reported the temp range from 42-54c, but I guess you're saying if the HSF is a little off maybe 1 or 2 cores, but not necessarily the whole cpu is overheating?

Prime95 (32bit) - 25.8 Download - EXTREME Overclocking

 

[Mayotruck]

43 sounds about right for your core but just check when your system is under load it will go up fast as soon as you start prime95 so be carfull please

 

[biosol]

What should I use as a max, 60 or 65?

Which test should I run, small FFT, large FFT, Blend?

 

[Mayotruck]

set max to 70 ...just be ready to shut down prim..blend

 

[Mayotruck]

you could even run sandrasoft if you perfer but whats the cpus under 100% load temps hitting

 

[biosol]

Ok, it's running. 55-58 on 3 cores. 1 core is not used prime said error.

 

[Mayotruck]

temp are fine then.

update your bois. Then try a memtest83

On the MB Bios page there is an update last 11/09. Here's the description - Fix DES version error Would that help?

And I'm running Prime again. This time all 4 cores working @ 100%. It took 17 minutes until Core #0 hit 70c, the other 3 right 63-66, Core #0 67/68 hit 69 a couple times and came down, then finally hit 70 so I stopped the test.

What does that say about the HSF/CPU connection and the RAM?

 

[Mayotruck]

it might, and updating your bois many times will fix errors(but then agian sometime it will not hah)

I would install it. upgrades are good XD

As for will it fix your problem not for sure no. but if you do update ypur bois make sure you are ready with a backup bois disk (google it) just incase something goes wrong.

I would update to the newest version and then check system stabilty...go play a game or run passmark benchmark.(google)

I was initially thinking it was temps because you recently re-seated your core... your temps seem fine but if you are leary just look up your processor and check it against other people's temps.. the max for your processor is 100 so, if you can hold prime for 20 minutes your pretty good.

but yah upgrade your bois. rember to have a backup ready unless you have duel bois but a backup is something you should have anyways ...just incase.

try lowering your memory speed (133Mhz worked for me) or try switching RAM Dimms/Simms. There errors are usually symptoms of memory problems. Also try to test you RAM using memtest-86 (Memtest86.com - Memory Diagnostic), it found some errors while my RAM was using a higher clock speed but none with my current 133Mhz.

If you look back at the diagnostics earlier just click on the link

[FONT=Segoe UI, Arial]This was likely caused by the following module: [FONT=Segoe UI, Arial]win32k.sys

If you click the win32k. it will bring you to google. and read there are lotrs of people having the same issues. If you have done anyhting to your ram lately reset it to to stock..

I actually had a simular issue so I pulled out my ram and moved them around from slot a to b and b to c and c to a.. upgraded bois and my problems went away..

it apears to be ram but I think windows 7 has some issues with ram which haven't been fixed yet.. because this is VERY common..click the link and read what your dump file told yah

btw I use [/FONT][/FONT][FONT=Segoe UI, Arial]a program called whocrashed(google) to read the dump files... its super easy 1 button

and its free.. i highly recoommned it

What do you mean by 133Mhz for the RAM? It's on auto now at 1066 I believe.

Actually cpu-z says DRAM Freq. is 533. Yeah, that's 1066.

Update: Ok, I just turned it down to 800.

 

[Mayotruck]

the 133 mhz ram thing was just cut and pasted from a forum i read about this error..
but i did have this issue and it was from playing around with my ram settings in cmos.if you set to stock and reset your bois. (upgrade as well) your problems might stop that what i did.

 

[biosol]

Ok, thanks a lot. I'm going to wait on the bios and cross my fingers turning down the RAM speed fixes it. Plus I have to record with WMC American Idol for my wife right now for the next two hours...
