BSOD without evident cause (don't know the code)

Hello everybody, I have this bsod that appears like... anytime and with no obvius cause. I atach the log for minudump, and not the system health report, because the last didn't have anything on red or orange, in other words, nothing to say.
Well, here are some of the specs of my system:

windows 7 ultimate x64 retail
the motherboard wich appears as "unknown" on dxdiag, is an gforce 6150 nForce 430. But as I sayd before, the health report doesn't say that there's no driver, and the device manager either.

Greetings everybody, I hope someone can help me

These crashes were caused by memory corruption/exception (probably a driver).
Please run these two tests to verify your memory and find which driver is causing the problem.


* If you are overclocking anything reset to default before running these tests.
In other words STOP!!!

* If you have Raid update its Driver.




Memtest.
Quote:
*Download a copy of Memtest86 and burn the ISO to a CD using Iso Recorder or another ISO burning program. Memtest86+ - Advanced Memory Diagnostic Tool

*Boot from the CD, and leave it running for at least 5 or 6 passes.

Just remember, any time Memtest reports errors, it can be either bad RAM or a bad motherboard slot.

Test the sticks individually, and if you find a good one, test it in all slots.

Any errors are indicative of a memory problem.

If a known good stick fails in a motherboard slot it is probably the slot.

RAM - Test with Memtest86+



Driver verifier

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 "Special Pool", "Force Pending I/O Requests" and "Low Resource Simulation" and click "Next"
- 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.

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.

Hi, thanks a lot for the reply. I've ran both test, and both show me errors. The memtest shows several errors, but I didn't use all combinations, so I don't know if is the slot or the card. But the other test, the verifier, sends me directly to bsod when I try logging on windows. So, I think it could be both, a driver and a memory problem.
I attach the new dump after all bsod.
And again, thank you a lot.

You are not supposed to run them at the same time. Memtest needs 6-8 passes and that takes quite a while. How many did you run?

These vere driver verified and Related to dtsoftbus01.sys Virtual Bus Driver from DT Soft Ltd. It is a known problem and needs to be removed. If you are running Daemon tools you can use this removal tool.


Please remove any CD visualization programs such as Daemon Tools and Alcohol 120%.

They use a driver, found in your dmp, called sptd.sys, that is notorious for causing BSODs.

Use this SPTD uninstaller DuplexSecure - Downloads DuplexSecure - FAQ

when you're done you can use this Freeware:

MagicISO Virtual CD/DVD-ROM (MagicDisc) in its place

Using MagicISO to create ISO image files
