BSOD UNEXPECTED_KERNEL_MODE_TRAP 0x0000007f after graphics driver

Hi,
Your crashes were caused by the generic monitor.sys which Windows loads for your monitor, and it seems to be related to the brightness calculation causing a EXCEPTION_DIVIDED_BY_ZERO fault.

Code:

UNEXPECTED_KERNEL_MODE_TRAP (7f)

STOP 0x0000007F: UNEXPECTED_KERNEL_MODE_TRAP

Usual causes: Memory corruption, Hardware (memory in particular), Overclocking failure, Installing a faulty or mismatched hardware (especially memory) or a failure after installing it, 3rd party firewall, Device drivers, SCSI/network/BIOS updates needed, Improperly seated cards, Incompatible storage devices, Overclocking, Virus scanner, Backup tool, Bad motherboard, Missing Service Pack

I would suggest uninstalling AVG and as an alternative:

Microsoft Security Essentials.

Recommended from a strict BSOD perspective, compatibility & stability
compared to other antiviruses/internet security software.

Microsoft Security Essentials - Microsoft Windows

   Note

Once downloaded, update and run a full system scan

Super hybrid engine is an overclocking software for Atom CPU's, this maybe causing
issues with your display, try updating to the latest version and then re-install the Intel drivers?

If updating Super Hybrid Engine/reinstalling Intel drivers does not work then:

Take memtest. Run for 8 passes and test each stick in a know good slot for an additional 6 passes.

   Tip

Run these tests overnight

Post back any results.

Hi,

Thanks for the feedback.

Was Windows XP the original O/S of the machine? As upgrading from XP to Win 7 can cause
driver issues, especially graphics. I installed Win 7 onto my mothers Asus eeePC 901 and had issues
with the graphics, the issue was that I had upgraded the BIOS which it did not like, so I had to
re-flash the BIOS with an earlier version, (I think it was Chipset issues), then I managed to get the
correct graphics drivers (Vista ones i think).

Also I see the driver you have installed from your msinfo32 file is:

Code:

 
IntelIntel® Graphics Media Accelerator 3150
Version: 8.14.10.1972
Dated: 10/15/2009

If you havent already try this later driver:

Version: 15.12.75.50.7.2230
Dated: 10/20/2010

Hi,

I would say if everything runs fine with XP/mint installed then as you say it is unlikely to be hardware issues.

I will ask for assistance with the monitor.sys issue, as monitor.sys is a protected system file,
it probably wont be directly causing issues rather something related, and once that is
sorted i believe it will stop your BSOD's.


It maybe wise to run SFC to check the integrity of all Windows 7 system files:

• Click on Start > Type in search cmd
  Right-click cmd after results are displayed and Run as Administrator
  Type SFC /scannow at the prompt
  (Note: There is a space between SFC and /scannow)

SFC Tutorial

   Note

Select option two. If any problems are found, run the scan 3 times and immediately
reboot the computer after each scan.

In addition, I have asked another member about monitor.sys and he suggested
that you may have more than one Intel driver installed.

After looking in your msinfo32 file, under "Problem Devices", it indeed shows that
2 different drivers/devices are present?

I would suggest to uninstall both devices in Device Manager, reboot and install the driver
I suggested in post #4

cheers

Hi,

If you found errors with SFC, then run 2 more times rebooting inbetween.
If you are unable to repair the SFC errors let me know.

I believe the solution to this issue is driver related...have you installed the 2010 driver i suggested? Same issue?

cheers
