Hello All,

I have searched for my problem and am at a bit of a loss. First my system:

Motherboard: A15G V1.0 (nothing else)
CPU: AMD Athlon 64 x2 Dual Core Processor 6000+ 3.00 GHZ
Memory 1GB
OS: Win 7 Pro.
Video: NVIDA GeForce 9400 GT

Everything was working fine, I had winXP pro, was running great, just upgraded to match my other computers on the network. It will not load into windows normally, it gets to the windows animated logo and the computer completely turns off (the logo does not fully load even). BTW this is not a temp issue. If I load it in safe mode, it shuts down after disk.sys is loaded. The only mode it will load with is debugging mode.

Does anyone know what's happening here? I'm working on the computer now, but it's loaded in debugging mode. I also can't get silverlight to work (for netflix), is this related?

Windows 7 is verified and registered.

Any help on this issue would be appreciated.

A few focused troubleshooting steps based on what reported and ’s suggestion — the fact Windows only boots in kernel debugging mode and Safe Mode dies after loading disk.sys usually means a driver or hardware initialization problem (video, storage controller, or power) is the most likely root cause. The Silverlight/Netflix failure is probably a symptom, not the cause, because protected video playback depends on a healthy graphics/driver stack.

From the working debugging session gather evidence first:

  • Enable boot logging (msconfig → Boot → Boot log) and inspect C:\Windows\ntbtlog.txt for the last driver loaded.
  • Check Event Viewer (System logs) for errors at the time of shutdown.
  • Turn off automatic restart on system failure to see a stop code if Windows attempts a BSOD.

Try these targeted fixes (in debugging mode or WinRE):

  • Uninstall the NVIDIA driver from Device Manager (remove driver software) so Windows falls back to the standard VGA driver, then reboot normally.
  • If that fails, power down and remove the discrete GPU, connect to onboard video and test. As suggested, this isolates any GPU/PSU interaction.
  • If Safe Mode always stops at disk.sys, change BIOS SATA mode to IDE/Compatibility (or the opposite, depending on how the OS was installed) and run offline checks:
    chkdsk C: /f /r
sfc /scannow /offbootdir=C:\ /offwindir=C:\Windows
  • If hardware is suspected: test with a known-good PSU, run Memtest86 on the RAM, or boot a Linux live USB to verify hardware stability.

If these steps don’t restore normal boots, back up user data and consider a clean Windows 7 install (upgrading from XP can leave incompatible drivers). Update chipset drivers and BIOS only from the board vendor and only if the update specifically addresses stability for your model.

Did you UPGRADE or Clean install Windows 7?
It sounds like once the Graphics card is initiated the system faults and powers off.

I suggest removing the video card and booting off the onboard video, see what happens.

What is the size of your Power Supply?
In debugging mode is Windows Aero being used?

I found your board online here:

I hope this helps in some way. Let me know what happens or if you have found a solution.
