BSODs with no specific pattern -- ntkrnlmp.exe

Hi guys,

I have been getting BSODs at random ever since installing an Intel 520 SSD. I did a clean install of Windows 7 Pro x64, and setup went smoothly, but then the BSODs started pretty much immediately. Windows update and driver updates did not help. These BSODs occur randomly, and I can't find any pattern to correlate my usage with the crashes. Sometimes, I even get blue screens when idling.

I used windbg to try to get an idea about which driver might be failing, and it says ntkrnlmp.exe, which isn't very useful. Can you guys help me out with this one? I'm totally at loss, and I might end up pulling out all of my hair haha . I've attached dumps + debugging info below!!


P.S.: Doing another clean install did not fix the problem. I've ran memtest86+ for about 24 hours and got nothing. Here are my specs:

Intel Core 2 Quad 9550
8GB RAM (4 x 2GB)
HIS Radeon HD 7750
Intel 520 SSD - 180GB

bump!

I've gathered all of the BugChecks: A, 19, 50, F7, 1E, 3B, C2, 7F, 24, FC, and 1000007E.

Please help!! I am totally stumped and really need to fix this as soon as possible so I can make work on my machine a little more bearable :)

Here's a few things I noticed, you have a lot of dumps, I just looked at the last few,

Your last dump is flagging your video driver,

Code:

Have you tried the driver from the manufacturer page?

Also, I notice you are missing a couple drivers,

Code:

PCI Simple Communications Controller	PCI\VEN_8086&DEV_29B4&SUBSYS_02111028&REV_02\3&172E68DD&0&18	The drivers for this device are not installed.

PCI Serial Port	PCI\VEN_8086&DEV_29B7&SUBSYS_02111028&REV_02\3&172E68DD&0&1B	The drivers for this device are not installed.

The Chipset drivers should fix that. It looks like there's only Vista drivers available,

They should work on Windows 7.

And you say you have 8GB of RAM but I only see 4GB being reported,

Code:

Installed Physical Memory (RAM)	4.00 GB

That's a pretty old computer, are you sure it supports 8GB of RAM?

How's the power supply? Can you put that in your specs, it will help others.

Thanks for getting back to me derekimo!

1) Video driver: This problem has actually been happening for quite a long time now (~2 years?!) I have simply dealt with the frequent BSODs but now am fed up with it. I have always installed the latest video drivers, and the problem still occurred all this time. So maybe I should downgrade and use a previous driver? What do you think? I am currently in the process of downloading the latest one to see if it works.

2) Chipset drivers: I just downloaded and installed those. **EDIT: the install doesn't seem to be working. In device manager, the PCI Simple Communications Driver and PCI Serial Port still are not being recognized.

3) Memory size: Oops, this machine really does only have 4GB (2 X 2GB). It's capable of 8GB though! I just have 2 sticks installed at the moment.

4) Power Supply: I have a 305W stock PSU. The model # is L305P-01 for anyone who is interested. I will update my specs with all these new changes.

In the very last BSOD, I had some tabs open, and a video was playing in the background I think. The rest of BSODs seem really varied, with some being graphics, some NTFS, and some ntoskrnl (or the like). If these driver updates don't end up fixing the problem, what may be the culprit??

Video drivers are probably one of the most common reason for BSOD's and sometimes the latest isn't always the best.

It may take trying a few different drivers, the one I linked from the card manufacturer seems to be a bit newer but worth a try if you've been getting them from AMD.

Thanks for adding your PSU in your specs.

Let's cross that bridge when we get there, it may take some folks with more hardware knowledge, but one step at a time for now.

So it turns out that the link from the card manufacturer had the same driver as my currently installed driver. Maybe they just updated the bundled software.

I doubt that the chipset drivers are causing the BSODs (or maybe they are?), but I haven't been able to successfully install it on my system, since device manager is still complaining about them

^Windows Action Center says that my version of Intel Active Management Technology isn't compatible with this version of Windows? That pertains to the chipset drivers.

Try the chipset without AMT, the third one,

You are changing the OS to Vista 64BIT correct?

Yeah, Vista x64 - Intel Chipset Driver (R174616.exe). - Still no success.

This may be a dumb question (I'm still learning this stuff haha), but could the fact that the PCI simple communications controller isn't properly installed and the fact that graphics cards are connected to PCI ports be related to the BSODs?

I think just about anything is possible with computers so I wouldn't rule it out.

What problem are having with the driver? What happens?

You can also try Compatibility Mode

So.. just had another BSOD. This one was a video driver for sure. The dump for this latest one is linked below.
