My first BSOD - System Thread Exception Not Handled

Hi everyone,

Here is the minidump file:

The main task I was doing at the moment of the BSOD (System Thread Exception Not Handled) was watching an mp4 video using Firefox if that matters, but I think it's just a random BSOD, and it's my first one. Never had one using Windows Vista x32 (the original os on my pc, when I bought it many years ago) nor on Windows 8 x32. I switched to 64bit system recently.

This is my computer:
OS Windows 8.1 x64
CPU AMD Phenom x4 9500
RAM 3,00 GB DDR2 @ 332 MHz (5-5-5-15)
BIOS Phoenix - AwardBIOS v6.00PG
MOBO Acer F690GVM (Socket AM2)
GPU Sapphire HD7750 2GB DDR3
PSU FSP Group ATX-250PA 250W
HDDs 298 GB Seagate ST3320820AS, 298 GB Seagate ST3320820AS, 3 TB WD Caviar Green WDC

In the meantime I was writing this post it happened again (System Thread Exception Not Handled - atikmdag.sys), here's another minidump:

Thanks to everyone helping me,

  1. Did you upgrade the established Vista system or do a clean install of Vista and then upgrade. Or, of course, simply do a clean install of 8?

    both bugchecks were in the graphics driver.
    -clean out the fans to the GPU, to make sure it is not overheating.
    - remove the overclocking software driver
    - maybe run memtest86 to confirm you don't have a memory issue that is corrupting RAM.

    actually, looks like your system was running pretty well so I would suspect the overclocking driver.
    (you could run verifier.exe on it set some flags to see if it is corrupting memory but I would remove it and see if you still get a bugcheck)

    You got a access violation in the video driver. I would suggest you remove this driver
    C:\Program Files\ATI Technologies\ATI.ACE\Fuel\amd64\AODDriver2.sys

    It looks like you are attempting to run a generic version of windows 8.1 on some very old hardware (2007) that might require custom drivers and BIOS updates.

    other than that, I would expect you to have problems related to actual bugs in the electronics logic because of the various specification changes that the current drivers are written to. Many of these changes actually require that the BIOS be updated by the vendor and that is not likely to happen.
