Windows 7: BSOD problem need help

BSOD problem need help

Windows 7 x64 Ultimate full retail version

- What is the age of system (hardware)?
3 months
- What is the age of OS installation
1 week

Worked smooth for first two months. Then don't know why PSU died. Got a new one from manufacturer. Maybe after that(not quite sure), often random BSOD.
What I did tried to solve it:
1. Software test (stress test, memtest86+), All pass
2. Reinstall windows 7 and install as few softwares as possible. Still BSOD.

Most BSOD happened after I logged in Windows and often continuous BSOD.
After quiet for one week, today it had two BSOD.

Need help and thanks!!!

Hi dxhcom and welcome



these two were both caused by memory mangement. I know you have run memtest but dont know for how many passes, etc.

It may very well be a driver that is causing the memory problem but it has not yet been identified.

You can


1-run a system file check

Run a system file check to verify and repair your system files.
To do this type cmd in search, then right click to run as administrator, then
SFC /SCANNOW

read here for more information SFC /SCANNOW Command - System File Checker

Let us know the results from the report at the end.

2-enable driver verifier to identify which driver is causing this problem.

Beyond that, please run Verifier with these settings:
Quote:
Using Driver Verifier is an iffy proposition. Most times it'll crash and it'll tell you what the driver is. But sometimes it'll crash and won't tell you the driver. Other times it'll crash before you can log in to Windows. If you can't get to Safe Mode, then you'll have to resort to offline editing of the registry to disable Driver Verifier.

So, I'd suggest that you first backup your stuff and then make sure you've got access to another computer so you can contact us if problems arise. Then make a System Restore point (so you can restore the system using the Vista/Win7 Startup Repair feature).

Then, here's the procedure:
- Go to Start and type in "verifier" (without the quotes) and press Enter
- Select "Create custom settings (for code developers)" and click "Next"
- Select "Select individual settings from a full list" and click "Next"
- Select everything EXCEPT FOR "Low Resource Simulation" and click "Next"
NOTE: You can use Low Resource Simulation if you'd like. From my limited experimentation it makes the BSOD's come faster.
- Select "Select driver names from a list" and click "Next"
Then select all drivers NOT provided by Microsoft and click "Next"
- Select "Finish" on the next page.

Reboot the system and wait for it to crash to the Blue Screen. Continue to use your system normally, and if you know what causes the crash, do that repeatedly. The objective here is to get the system to crash because Driver Verifier is stressing the drivers out. If it doesn't crash for you, then let it run for at least 36 hours of continuous operation (an estimate on my part).

Reboot into Windows (after the crash) and turn off Driver Verifier by going back in and selecting "Delete existing settings" on the first page, then locate and zip up the memory dump file and upload it with your next post.

If you can't get into Windows because it crashes too soon, try it in Safe Mode.
If you can't get into Safe Mode, try using System Restore from your installation DVD to set the system back to the previous restore point that you created.

If that doesn't work, post back and we'll have to see about fixing the registry entry off-line:
Code:
Delete these registry keys (works in XP, Vista, Win7):
        HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\VerifyDrivers
        HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\VerifyDriverLevel
More info on this at this link: Using Driver Verifier to identify issues with Windows drivers for advanced users

Also there are several drivers that while not involved in these crashes are known to cause them.

SPTD.sys used in daemon tools and alcohol is the first that comes to mind. I always recommend its removal.

I also see some USB drivers (for what appears to be hubs) how many un-powered usb devices do you have?

Thanks very much, Ken.
I will try what you suggested.

I have maybe 3 unpowered devices connected: mouse, keyboard, flash drive.
My motherboard has two USB3. A driver was installed for them. But I never use them.

1. First time ran sfc, BSOD; second time, pass. No repair made.
2. After enabled driver verifier, start up several times all with BSOD. The dump files are in attachments. A drive named usbfilter.sys showed on screen.
