Windows 7: Sudden onslaught of BSODs

Sudden onslaught of BSODs

I have had 6 BSODs in the last couple of hours, after weeks of almost trouble free usage. I have attached a zip file, and would appreciate someone taking a look for me.

Hi and welcome

this one was probably caused by memory corruption. I would download memtestx86 and run it for 5 passes

run a system file checker
type cmd in search>right click and run as adim>sfc /scannow

Many thanks for the welcome and the very quick reply - I will do as you suggest straight away.

I burned memtest86 to DVD and did 5 passes. I was a little confused about what it was doing as it went straight to reboot after each test, but I take it that it would have halted on an error?

I then did a system scan, with no integrity problems.

Is there anything else I should do?

No problems seen today.

It could all be down to power supply issues in this area, with us having white-out conditions and neighbouring villages cut off completely.

I am still not entirely sure that I am using memtest86 properly.

Memtest will run until you turn it off. If you don't see errors at the bottom of the screen (in bright red), it's usually OK. Here's an image w/errors:

Please try running Driver Verifier according to these directions:
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"
- 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.

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.
