Windows 7 BSOD on video playback

[MPC]

I am testing windows 7 on a machine and there are a couple of things that are causing me some grief. One of which is not too bad but the other is a real problem.

The first problem is when I enable the AHCI SATA in the bios windows won't load it gets to the loading screen and then BSOD and reboots. When I disable this and run in IDE mode everything is fine. The experience index for drive data reading is 2.9 which if I am not mistaken is due to the mode that the SATA is being read.

The other is the major issue and its associated with video playback. Whenever I am watching any videos Xvid/DivX I get BSOD after only a few minutes. I have tried many different videos with the same result.

Here are the fixes I have tried:
1. Installed VLC - Still BSOD
2. Tried the windows update driver for GPU and the Latest release from Nvidia Specific for Windows 7
3. Tried 3 sets of Realtek audio drivers for the onboard sound
4. Installed Klite codec pack to try see if it was a codec problem.

None of the above have solved the issue I have reverted back to the original setup and I am at a loss. There is nothing else going wrong so far other than this. No BSOD except during video playback.


System Specs:
Windows 7 build7000 64bit
Q6600 Quad
Gigabyte EP45-UD3R
4GB Corsair Dominator
BFG 9600GT
250GB Sata2 Seagate Baraccuda 7200.10

Thanks for any assistance.

It looks like you're facing two main issues while testing Windows 7 on your machine: one related to enabling AHCI SATA mode in BIOS causing a BSOD during Windows startup, and the other involving BSOD during video playback, specifically with Xvid/DivX files. Let's address these problems one by one:

AHCI SATA Mode BSOD Issue:​

• Symptom: Windows fails to load when AHCI SATA mode is enabled in BIOS, leading to a BSOD during startup.
• Probable Cause: This may occur due to a lack of AHCI drivers in Windows 7 when switching from IDE mode to AHCI mode.
• Potential Solutions:

1. Enable AHCI Mode with Registry Change:
   • You can try enabling AHCI mode in Windows by making a registry change before switching the BIOS settings. This method helps Windows load the AHCI drivers during startup.
   []AHCI Drivers Installation:
   • Another approach is to install AHCI drivers in Windows 7 to support AHCI mode. You might need to manually install the drivers within Windows.
   []BIOS and Driver Updates:
   • Ensure that your BIOS is up to date and that you have the latest AHCI drivers compatible with Windows 7 for your motherboard.

     BSOD During Video Playback:​

     • Symptom: BSOD occurs consistently during video playback of Xvid/DivX files, despite various troubleshooting steps taken.
     • Potential Solutions:
   []GPU Driver Update:
   • Ensure you have the latest GPU drivers installed. Consider performing a clean installation of the GPU drivers to rule out any driver conflicts.
   []Codecs and Media Players:
   • Try using different media players like MPC-HC, PotPlayer, or KMPlayer to see if the issue persists. Avoid using codec packs and prefer standalone codecs.
   []System Stability Check:
   • Run diagnostic tools like memtest86 to check for any memory issues that might be causing the BSOD during video playback.
   []Temperature Monitoring:
   • Monitor your system temperatures to ensure there are no overheating issues causing instability during video playback.

General Recommendations:​

• Windows Update: Ensure your Windows 7 installation is fully updated to patch any existing issues related to stability and compatibility.
• System Cleanup: Perform a disk cleanup, check for malware, and optimize your system for better performance.

Try these steps and let me know if you encounter any specific errors or need further assistance with implementing the solutions.
