Windows 7: BSOD on new PC

02 Aug 2010   #11

Microsoft Window 7 Professional 32 bit

The results from the DMP files do not give a definitive answer. While we investigate further here are a few things that you can do.

1-Run a system file check to verify and repair you system files. You do this by typing cmd in search, then right click and run as admin. SFC/ SCANNOW

2-Download a copy of Memtest86 and burn the ISO to a CD using Iso Recorder or another ISO burning program. Boot from the CD, and leave it running for at least 5 or 6 passes.

3-Event viewer
Go into event viewer (type eventvwr in search). Go to the windows log>application tab.

You want to look for critical errors (they have red in the left column ).

When you find them you want to look for critical errors that say app hang, app crash, or anything that relates to the problem.

When you find them please note the event ID, and the source codes and tell us what they are.

4-Device manager
Please go to start>search>type device manager.
Are there any "unknown devices" with yellow triangles on them?
Is you driver there , listed, and working?

If y our driver is missing, or there is a yellow triangle on it, you will need to update it.

5-Driver verifier
please run Verifier with these settings:
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:
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

Nothing in device manager, sfc /scannow came back ok. I ran memtest over night...9 passes no errors and still the blue screens. 3 after my last post.

Anyway, I've just been on the phone to the company that I bought it from and it's been RMA'd and going back today for testing etc

If it had just started happening after having the PC for a while then I would have stuck with it but the fact that they have been happening from the moment I got the PC on Saturday then something is wrong somewhere and I think it's up to them to sort it out.

Thanks again for your help, much appreciated.

Ok, quick update.

Sent machine back last week...turned out to be faulty RAM. They replaced it and it's now working perfectly :)

Thanks again for the help.

Another update....I spoke too soon, blue screens started again so I'm sending it back and getting a refund.

What is it with "new" computers these days they just don't seem to be as reliable as they used to be.

I'm now back on a temporary 6 year old celeron that is so slow I keep thinking it's about to stop but it works...has not had one thing go wrong with it since the day it was bought. Hmmm that's tempting fate a bit

I agree! hard question to answer but yes, new computer these days are not as reliable as before. I have heard somewhere a joke that, in order not to have BSODs, you should not install any 3rd party software, far away from your computer
