Vista - Random BSOD

Sorry if this is posted in the wrong section.
Maybe someone can help me with my problem.
I have been getting random BSOD ever since I built my computer.
I have reinstalled drivers and programs numerous time looking for
the cause but have come up empty handed.
My most recent BSOD is as follows:

Problem signature:
Problem Event Name: BlueScreen
OS Version: 6.0.6001.2.1.0.768.3
Locale ID: 1033
Additional information about the problem:
BCCode: 3b
BCP1: 00000000C0000005
BCP2: FFFFF960000AC669
BCP3: FFFFFA600D94DB60
BCP4: 0000000000000000
OS Version: 6_0_6001
Service Pack: 1_0
Product: 768_1

My system Specs are:

Gigabyte M59SLI-S5
AMD Athlon 64 X2 6400+
Nvidia Geforce 8800 GTX
4 Gigs of Corsair CM2X1024-6400C4
Creative X-Fi ExtemeMusic
WD Raptor 74Gig HDD
Samsung writemaster DVD-RW
Windows Vista Home Premium 64

Nothing is overclocked and temperatures have always been normal.
The BSOD are random and cannot be linked to anything specific.

I have got BSOD that say the following as well:

IRQL Not Less or Equal
Page Fault in NonPaged Area

Does anyone have any ideas as to what can be causing this?
I have run memtest on my memory numerous times and it always checks good.
I have tried old and updated drivers on all my components with no luck.
Sometimes the computer will go weeks at a time without a BSOD and sometimes
it can get numerous BSOD in a day.

After searching the web for hours I still cannot figure this out.
Any help would be greatly appreciated.

Any Ideas?

Hi tiltrotor22, sorry can't come up with definite answers.

Here may be some thing you probably have already done, just take it as a reminder.

I supposed you have reinstalled Vista but problem persists, you have check your SATA cables or replaced them with aftermarket ones (makes lot of different which took care of my BSODs).

What is left, I suspect, is over heat problem. The nice Apeiva case has excellent air circulation, there for I would narrow it down to the CPU HSF unit and the GPU.

I would remove the cover of the 8800GTX and blow it out thoroughly. Next, I would reinstall the HSF assembly to make sure a good consistent contact, not too much thermal paste. The huge Chilltec cooler is way heavy, I may install a small piece of something between the HSF and some where on the case to take off some torque off the CPU and the MB.

That's all I got on this to this point; hope it is better then nothing. Good luck and post back.

Ok, here is an update to my problem. This might help clear things up.

My computer crashed again, this time when I reset it the monitor would not come on. It has done this a bunch of times but usually I wait a while and reset it and it comes back on. Today was a different story though, it would not come on no matter how long I waited.

I decided to remove one stick of ram from the 4th slot. Once removed the computer started normally and the monitor came on and everything worked great.
I then shut down the computer and installed the ram again. The computer again turned on and has been running great.

Ive already done tests on the ram and have done another and it all checks good.
I have read things on the internet about some boards or windows vista 64 having problems when 4 ram sticks are installed. Could that be the problem?

Anymore ideas?

By the way, cooling is not an issue and the heatsink is mounted correctly and is not really pulling on the board. I cant count it out but I highly doubt the heatsink or processor has anything to do with my problem.

That is really strange; I have 4 GB like yours but never has any problem together. I heard the 2 GB sticks give this sort of problem but not the 1 GB sticks. Well, how about start to swap out each ram to see if there is one ram or slot that having problem. How about leaving one stick out for a couple of weeks see it problem ever come back so you can say that is it. I still has slight suspecting the SATA cables because those Raptors are very fast that generates buzzing vibrations which would easily knock them partially loose. Replace them regardless.

One curious question, why didn't you install your OS in the RAID drives? I thought a speedy OS is most important. Well, I did put everything in the RAID, games and all.

irq not less equal video drivers

page fault in non paged area could be anything , mostly hardware related though

next time you bluscreen let windows create a dump file (you'll se it dumoing physical memory its a count down bottom of your blue screen) then make your dumpfile available for download and i can take a look at it for you.

your dumpfile is located in a folder called minidump its in the windows on your c drive

i have fpur sticks of memory and i had to up the voltage to the memory to make it completely stable , you could try that

look up your ram specs most boards bios voltage setting for DDR2 is 1.8v , faster ram runs at 2.1v so you may be undervolt anyway , this would cause alsorts of errors , if the voltage is ok just up it by .1 of a volt see if it helps (Thats .1 ie point 1 not 1 )

Hi tiltrotor22

The only way to really be sure with memory is to check each stick in each slot separately and then in each possible combination - and without a specialised test rig, all the combinations would probably take you a very long time

best I can suggest is test each stick on it's own in slot1 to confirm the ram and then using I stick individually in each slot to check the slots. If all these pass then it's has to be either a compatibility problem between the sticks or a problem with the board not liking all slots filled.

At least this way you should know if you have a bad slot or stick
