BSODS, The continuing story Part 2

[Chalky Skipper]

Hi Tuan and Tews,

Hopefully you might remember my previous thread, which finished 2 days ago on an optimistic note.

Following on from tests performed etc, I restarted my system almost 48 hours later to test cold start. Unfortunately system had 3 blue screens and black screen before stabilising.

I have attached as much info as could muster from the blue screens. Somewhere in there might be a solution

Thanks again,

Regard,

Chalky

Hi Chalky

This one is pretty straight. Its your PCTools, specifically PCTCore64.sys. I would uninstall it and see if the problem goes away. You can always re-install it later

Sorry if I forgot result last time, but it would be best if you can run memtestx86 for at least 5,6 passes to eliminated memory corruption

Hi Tuan,

THanks for quick reply, will uninstall Spydoctor and wait another 48 hours.

You obviously don't sleep,as, according to my clock it would be around 0450 hrs in your neck of the woods when you posted the reply.

Will advise result.

I'm home in Vietnam for summer. You live in Australia right? So probably we are not much different in time. I'm going back to United State in September and time will be much much different by that time. Hopefully remove PC tool will solved the problem.
What other antivirus software are you using? Again, third party software especially antivirus, are potential cause for BSODs, no matter it is blamed directly in the dump file or not?

 

[Chalky Skipper]

Hi Tuan,
Looks like only about 3 hour difference.
I had Kaspersky on system,however it appeared to be playing up so uninstalled, tried Comodo but had problems with that as well and looks like Spydoctor also travelling same direction. Now wondering what protection I can put on without causing problems.

Regards,

Chalky

 

[Jonathan_King]

Install Microsoft Security Essentials: http://www.microsoft.com/security_essentials

Guaranteed not to cause problems.

 

[Chalky Skipper]

Hi Jonathan,

Thanks for advise. Will certainly give it a go

The Story so far

Hi,

Need help to sort out ongoing problem. Have have 2 previous threads with this problem but still no luck in sorting it out. Last thread was about 3 weeks ago, so thought it better to start new one.

Have been having BSODS for months,having initially built system in February.

The system is Windows 7 x 64 ultimate, it was purchased retail at same time as other computer components.

Following is a list,as best I can remember, of what I have done to try and rescue system.
1.. Reinstalled OS on 2 occasions
2.. Clean install with new hard drive.
3.. Changed Video card
4.. Run disk check
5.. HD diagnostic,passed short and long
6.. Memtest x86, 6 passes no errors
7.. Sfc/scannow, all clear
8.. Repair install
9.. Tried different protection software, including Kaspersky, Spydoctor,Comodo, Norton and currently using Microsoft Essentials.

Have attached zipped files for Bsods and perform. Hopefully these might give enough info for rectification.

Thank you for your time,

Regards Chalky

I see you have run memtest but the DMP's are still pointing to memory. Did you run it one stick at a time, and did you test the mobo slots one at a time with a known good memory stick?

Hi Zigzag,

Thanks for looking at problem for me.

I took both memory sticks back to store for testing and they confirmed both sticks o.k. . I then run my own test , first, with both sticks and then individually. I used only mobo slots 1 and 3 when testing.

Regards, Chalky

 

[Jonathan_King]

PC Tools still needs to be removed.

Update your nVidia drivers: Drivers - Download NVIDIA Drivers

Update your Intel Wireless drivers. Check on your computer manufacture's site.

 

[CarlTR6]

Chalky, Jonathan is right. Win 7 does not need any third party tuneup utilities or tools. It is a new OS, not at all like XP. These third party utilities usually cause far more problems than they resolve. Windows 7 is very good at taking care of itself; it does not need tweaking.

 

[Chalky Skipper]

Hi Tuan,Tews, Jonathan,Zigzag3143 and Carttr6,

Just like to give update on my Bsod problems.

You continued to suggest memory as the primary cause so,

after last post I decided to run memtest again and did so with up to 9 passes ,testing sticks together and individually, using channels 1 and 3. The result was still no errors.

At this point I decided to spend some more money and bought 2 new sticks,exactly the same as what I already had. I figured that if it wasn't memory then I could at least increase memory size on system. Using the new sticks has changed the system to the point it actually acts like a computer should. NO CRASHES. I also tried using the old sticks with new ones, however, once again it started to become unstable, things like Internet Explorer shutting down for no reason etc. Reverted to new sticks only and ,once again, success.

I will take old back to store, for the 2nd time, and show them evidence from this forum that they are obviously dud and hope for replacements.


Just like to thank you guys for all the help offered on the problem.


Regards,

Chalky

 

[Jonathan_King]

Thank you for the update!

If you have a few minues some day, would you mind testing your bad RAM sticks with Prime95? Here is a tutorial: http://www.sevenforums.com/tutorials/100352-cpu-stress-test-prime95.html

The instructions will be the same, except that you will want to select "Blend".

 

[Chalky Skipper]

Hi Jonathan,

As requested I have run a 12 hour Prime95 test on bad sticks and, suprisingly, ( to me ,anyway) did not 'miss a beat'.

When I changed back to these sticks the system crashed twice before it stabilised, so I was surprised when it went the 12 hours without a hitch.

Any further ideas on the problem would be appreciated, however, I think ,even without Prime95 test ,I have enough prior evidence to get replacement ram.( Or at least I hope I have ).

Once again thank you

Regards Chalky

 

[Dave76]

Did you run the Torture Test - Blend?

Prime95 > Options tab > Torture Test > select Blend, number of test threads 4.

Did you check temperatures during the test?

Use Real Temp to check the CPU core temps.

D/L CPUZ and post the memory and SPD tabs, check the BIOS for the DRAM and QPI voltage.

Have you done any overclocking?

 

[Chalky Skipper]

Hi Dave,

Thanks for reply.

Following is info you requested ( or I think it is ).

I used Speedfan with test and the temperatures for 4 cores averaged between 72 and 78 degrees, mainly around 74-75 during the 12 hours.

Used blend test , 4 test threads

DRAM voltage is 1.5, QPI/VTT voltage is 1.100. Both these are set on auto.

Attached are CPU-Z readings of system.

Hope this info ok

Regards,

Chalky

 

[Dave76]

Thanks for the info.

It's better to use the snipping tool and post the picture.

This makes it easier for all of us to see the information.

Is your motherboard rev. 1 or 2?
Your BIOS is F3.
Both rev.1&2 are showing current BIOS version as F13, you might want to consider updating the BIOS.
There was a 'Enhanced memory compatibility' listed a few versions back, the BIOS upgrade may help.
This can be risky, doing it wrong can brick your computer, if you read up on it first you should be OK.
Let us know if you have any questions.


Your DRAM voltage should be fine.
You should bump your QPI/VTT voltage to 1.150 and see if this helps the two suspect RAM sticks, if the BSoDs stop your good, if not then bump the QPI/VTT voltage to 1.190 and check for stability (see if it BSoDs). Max QPI/VTT voltage for your rig is 1.200, same as mine, although mine shows a 1.210 option before they are in red font.
This will make the RAM more stable, maybe even the two sticks that caused your BSoDs.
Unless you have returned the two old ones already.
Then, keep this in mind if there are any more BSoDs.

Intel states the max temp for our i5-750 CPU is 72.7c, I've seen a lot of people that run them up to 80c, but I like to keep mine cool.
With my OC at 3.8, it stayed under 70c when running Prime95. I have a 'reasonably priced' (U$30) Cooler Master Hyper 212 Plus CPU cooler.
Just about any CPU cooler will be better than the Intel stock cooler.
Something to think about.


Let us know if you have any questions or if everything is running good with the new RAM sticks.

 

[Chalky Skipper]

Hi Dave,

Thank you for your very informative reply to my post.

Firstly, in answer to your question ,my motherboard is rev.1.

I have now boosted my QPI/VTT voltage to 1.150 and will now leave computer switched off for 48 hours, as it seems this is period of inactive time required before it ' spits the dummy'. If this doesn't work will boost to 1.190 and see what happens at that level. For your info mine also shows a 1.210 option. I still have the old sticks and will use those with the increased voltage setting.

I thought mid 70's in prime test was a bit above suggested limits and will certainly look at replacement CPU cooler to improve cooling.

I am a bit reluctant to do a BIOS upgrade,risking,as you say, bricking the computer, however, 'if push comes to shove' I will have a go at it. Hopefully it can be avoided.

I will post my results as soon as I can.

Thanks again

Regards,

Chalky
