Windows 7: Three BSODs in the last year. No activity connection.

Three BSODs in the last year. No activity connection.

In the last year, I've had three BSODs at various times. Once, it happened while I was playing a game, and I assumed the problem was with either my graphics drivers, my graphics hardware, or with the game itself. The second one, however, came while I was using Writer, and the third happened this morning, when I was browsing the internet. (I think I have those first two right. I might be wrong, and the .dmp files might show it. After all, it's been a while, and I'm old and my memory is faulty. *chuckles*)

I know three BSODs might not sound like a lot, but I'm moderately concerned, and have no idea how to read .dmp files. I've attached the files, in case that helps, all in one handy .zip.

Thank you, in advance, for your assistance.

Win 8 Release candidate 8400

Three different dates (Sept, Nov, and now) and three different causes. The only one relevant is the most recent and it was caused by memory management (probably a driver).

The first was hardware, the second inconclusive, and now memory management. These might all be one offs and the cure might be worse than the disease.

If you want to follow through these tests will help you find out which driver.

These crashes were caused by memory corruption 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 a Raid update its Driver.

*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 5-7 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.

Driver Verifer

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.

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).

In Windows 7 you can make a Startup Repair disk by going to Start....All Programs...Maintenance...Create a System Repair Disc - with Windows Vista you'll have to use your installation disk or the "Repair your computer" option at the top of the Safe Mode menu .

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.

If you are using win 8 add these

- Concurrency Stress Test
- DDI compliance checking

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.

BSODs on seemingly any activity, error 0x00000124
Hey all, Just started encountering bluescreens after about 6 weeks of none (the previous bluescreens were caused by RAM which is now RMA'd, and I have not inserted any new RAM). These BSODs happen when I'm idle, gaming, browsing, etc. My hardware is still relatively new and I do not have any...

BSODs during long periods of activity, 4-5 hours.
I just started having bsods on a brand new harddrive (and 8 gb ram) that replaced a bad one. Recently, the bsods happen randomly after about 15-30 minutes of activity and have changed to just black screens, then restarting the boot process.

BSODs constantly regardless of current computer activity.
It is a computer that I built myself and it has constantly blue screened on me since it was built. Sometimes it will go a couple days in between and other times it will just be one after another after it reboots itself. I believe I correctly attached the dump files. Any help would be appreciative.
