Solved BSOD help (bad pool header & irql less or not equal)

[adabisi]

Hello,

I have a new pc:

CPU: Intel Core i7 4770
SSD: Samsung 840 EVO 120 GB
HDD: Western Digital caviar blue 1TB
Memory: G.Skill 4X4GB
GPU: Zotac GTX760

After installing windows 8.1 and official drivers from the web and discs, twice, I keep getting BSOD, bad pool header & irql less or not equal randomly. I installed windows 7 Ultimate 64 bit, hoping it would solve the problem, but i keep getting the same blue screens crashs.

could it be a hardware related problem?
is it possible that Zotac GPU and the on board GPU clash? becase i disabled the on board device.


Thank you.

Fix bad pool header bsod

I faced this problem 2 weeks ago. But i have fixed it with the help of my friend's instructions. I would also suggest you to follow these steps to fix your problem.

- Disconnect External Devices
- Safe Boot Windows
- Update Device Drivers
- Repair Windows Installtion
- Disbale Security Software
- Repair your Registry with Reginout or Ccleaner

Thanks, hope it will works.

Thaks for your reply Glenda.

I've returned the pc back to the store for a checkout.
They found a problem with the GPU, which they have replaced and also did a BIOS update.

Unfortunately after I reinstalled windows 7, I connected a TP LINK (USB), before any driver installation, I downloaded Chrom, and during its installation I got a blue screen.

So, by this cronologic order, in which the drivers handn't been installed yet, on what could I blame the BSOD?:shock:

Please post an up to date relevant SFDT .

After a second checkout at the computer lab, in which they did different tests and ran it all night long, without the computer crashing even once ,I took it back home and replaced all devices conected (screen, mouse, keyboard) without connecting the TP LINK device at all.

I used only the USB2 plugins to connect the mouse, and connected the keyboard threw a PS input.
And so, I checked each and every USB input with a flash drive, giving each a couple of hours.
Although it was not immediate, after pluging in a USB3 on the front of the pc I got a BSOD.
all other plug ins where fine except another USB3 exit on the back.

Don't know if I'm going with a good lead... heres the lateset report.:huh:

Thank you

an updated SFTD

Two more bsod.

one during a Mdsched.exe memory check, and another during an error-check scan on my SATA drive.

I've rescanned both and they turned out to be fine.:shock:

 

[adabisi]

I have abandoned the USB test that was not decisive and started a RAM test.
first stick out of 4 was BSOD free for 3 days.

fingers crossed...

 

[YoYo155]

Sorry I couldn't reply sooner.

Since you removed one of the sticks did you try to trigger a BSOD when using the USB3.0 ports?

 

[adabisi]

I tried to connect all the "bad" USBs with which I have experienced a BSOD, but I haven't gotten any crashes.

How can I try and trigger a BSOD? beacse all I do is work on Lightwave and surf the web...
any attempts to repeat actions that caused a BSOD failed.

Well that's good news then!
What I meant was that try to use the USB3.0 ports as you did before which resulted in a BSOD,
now that it doesn't that is a pretty strong lead that the issue is the stack you removed.

Keep us updated .

Hey,

I have tested all of my four 4GB RAM stick individually, and I did not get a BSOD during each test.
But, when I plugged in 2 RAM sticks to the first Dual channel, I got a crash after an hour.

Now I have one stick in each channel. waiting to see how it goes now.

note:
when windows started while I had 2 sticks plugged in ( one channel and dual channel both)
the system was fidgety for a couple of seconds and a weird noise that sounded almost electric was coming out of my speakers during that.

here as an up to date crash report that includes the new latest crash.

Ok let's start fresh and make sure we are configuring the RAM the correct way.

Take out both modules and look at them from the thin side so you'll be able to see in-between the heat-spreader and the chips themselves. Do you see chips on both sides of the stick (I believe
that the F3-12800CL9-4GBRL should be single sided)?

Now that you have that information about the modules follow this diagram according to the type of
modules they are (Single-Sided / Double-Sided).

View attachment 298463

Please install the modules in DDR_1 & DDR_2.
DDR_1 & DDR_2 are referring to the light gray slots which are the furthest away from the CPU socket.
After doing so please enable the RAM XMP profile in the BIOS.

 

[adabisi]

The modules are double sided.
I have installed two modules in the slots you said and changed the ram xmp from "disabled" to "profile 1", hope that is what you mean.

By the way, I have conducted a "memtest86" for five hours,while all of the modules were connected, and it turned out to be OK as far as I understood.

Yes that is what I meant .
Memtest is by no-means the gold standard and faulty modules can pass without a hiccup,
but it's good for most cases. Also five hours doesn't say much we count passes not run time.

 

[adabisi]

it was two passes

Do you mind explaining what the XMP status is?

Say I don't have any crashes now, the next step is to check the other modules in the second channel?

That is not nearly enough .

XMP stands for eXtreme Memory Profile,in a nutshell, supported memory modules have profiles assigned
to them by intel and implemented by the motherboard to set timings and speed of which the specific
module model should operate under, as the motherboard defaults to running the RAM at 1333MHz for better compatibility XMP is set to run the RAM at it's tested speeds. Most mainstream have modules have only XMP profile but more high-end ones have two or three which overclock the RAM.

No, as you can see in the diagram above, two modules are to be used only in DDR_1 & DDR_2.

Happy new year

I have checked all four modules pair by pair, with the XMP enabled using the right sockets, as you said, no crashes at all !
I've re-installed all of the modules tougher, should I disable the XMP now ?

what do you suggest I should do next?

Happy new year .

No no, leave the XMP profiles enabled they are designed to run the modules in the most correct fashion.
Happy you have it sorted now, if you feel the thread is solved please mark it as so.
