UNEXPECTED_KERNEL_MODE_TRAP - STOP: 0x0000007F

Hello,

sorry for the bad english, I´m from germany.

My problem. I bought an W870CU Clevo based Notebook. Its called mySn XMG7.c .

My problem is, that I´m getting BSOD:

UNEXPECTED_KERNEL_MODE_TRAP 0x0000007f
ntoskrnl.exe
ntoskrnl.exe+70740
NT Kernel & System
6.1.7600.16617 (win7_gdr.100618-1621)
x64

Tested the RAM, tested with 3dmark Vantage, HDTune, Prime95 (blend) for some hours - no errors.

What should I do next? :-(

 

If you can, it would be best to just reinstall windows from a clean OS disc (unless you have installed tons of stuff and have all of your data on it, I'm assuming its "new from the factory").

If you don't have one, you can get it at the guide linked in my sig.

 

Hello v3loc1ty2.0.

Its a fresh original version of Windows 7 on the 64gb SSD I put into the Notebook.

Just the needed drivers, like graphic, realtek 2.51 hd audio, wlan driver and so on. But nothing special. I installed it yesterday, as I received the notebook.

 

That's a bad one, usually a bad driver will do that, but I can count on one hand the amount of times thats happened to me on an NT kernel. I'd almost say it's a hardware problem. When you get an error like this, it's usually something very low level malfunctioning because it's interfacing with the NT kernel and causing it to become unstable.

 

Install "WhoCrashed" and maybe you'll get more information.

The crash took place in a standard Microsoft module. Your system configuration may be incorrect, possibly the culprit is in another driver on your system which cannot be identified at this time.

This happens, when I´m in World of Warcraft, switching to the desktop and then back to the game, then bsod comes.

 

Then it's quite obvious the issue is the graphics driver. Do you have the 5870m or the GTX285?

 

Its a 5870m. But I just have the driver from the website from the online shop where I bought it. Is there a way to find a better one? I downloaded one from AMD.com but I cant install it somehow!?

 

Installed the latest official drivers. 8.762.0.0 now.

Same problem.

Some ppl say, it could be the RAM of the graphiccard too?

 

I experienced random crashes in ntoskrnl.exe because of a faulty RAM module. After replacing it with another all is fine.
All previous RAM tests(memtest86+ for hours) showed no error. I experienced also random BSOD's with high density memory in an AMD mainboard. After changing the memory for low density the BSOD's stopped.

 

I understand the first things. Can you please explain in other words, what high density and low density means, I dont understand what it means.

 

If you can't get the drivers from AMD to work, then try using Mobility Modder to make them work: Mobility Modder - ATI Version, Install the Latest Drivers on your ATI laptop

 

Take a look at
Info: What is the Difference Between Low Density and High Density RAM? - Overclock.net - Overclocking.net

Low density memory is usually compatible with all motherboards, high density is not.

 

Okay, I wanted those - from Kingston:

Kingston HyperX SO-DIMM Kit 4GB PC3-8500S CL5-5-5-15 (DDR3-1066) (KHX8500S3ULK2/4G/KHX1066C5S3K2/4G)

Are those "okay" ?!

 

I don't know. The configurator at
Schenker Notebooks - Xtreme Mobile Gaming | mySN.de - XMG7.c 43,9cm (17,3") Gaming Notebook
offers only 1333 MHz DDR3 memory. Yours is 1066 MHz.

 

Its compatible... 1066 and 1333. I asked the german clevo support. Problem is, I changed to a Crucial RAM and I have the same errors... now im clueless... dont know what to do. :-(((
