Windows 7: Random Bsod's

Random Bsod's

Hi, I have been having this problem for a while now and am finally sick of it and decided to get some help from the experts. Please take a look at my files and see if you can find anything wrong. It will bluescreen doing almost anything from web browsing to gaming. sometimes it will freeze and not reboot but If I take the memory out and switch slots it will start and is fine for a while till it crashes then I switch it back. Ihave run memtest on the memory. I think it was 10 passes each stick in each slot and it passed fine. Thank you,Bill

Hello Bill701 and welcome to Sevenforums.

BSOD Analyse

I'm throwing you directly into 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/Windows 7 Startup Repair feature) - and create a System Repair Disc (Windows 7) if you don't have a full installation DVD.
You can do this by going to Start...All Programs...Maintenance...Create a System Repair Disc (don't forget to test the disc to make sure it works).

For Vista, you can download the repair discs from different websites. If unable to locate them, shoot me a PM and I'll point you to them.
For Win8, BSOD's are different - and we'll have to adjust how we do this with them.

Also, to ensure that you can recover, here's another couple of additional steps:
- Get to the Safe Mode menu (rapidly tap F8 just before the Windows splash screen comes up). Scroll down to and select "Disable automatic restart on System Failure"
- Get the RED information from this picture (in particular we will need the name of the file that the error occurred in):
Picture of a BSOD

Then, here's the procedure to run Driver Verifier:
- 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 "IRP Logging", "Force Pending I/O Requests" and "Low Resource Simulation" and click "Next" ("Special Pool" may be able to be used depending on amount of RAM and errors being seen. In situations with small amounts of RAM, DO NOT select it),
- 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 locate the memory dump file. If present, turn off Driver Verifier by going back in and selecting "Delete existing settings" on the first page. Then, zip up the memory dump file(s) and upload them with your next post. If no dump files were generated, post back for further suggestions.

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 to stop Driver Verifier from loading (works in XP, Vista, Windows 7):
        HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\VerifyDrivers
        HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\VerifyDriverLevel
Best Regards,
Frederik.

Thank you for the response. I turned driver verifier on and it bluescreened on reboot. I rebooted again and the screen was just black and there was static coming from the speakers. I tried to restart again and just got 4 long beeps and it wouldnt start. I switched the memory to the other slots and it rebooted but still had static from speakers. I disabled verifier and rebooted and the static went away. I have attached the minidump file. Thanks for your help. Bill

Alright, good job.

Combining your crash dumps and the general view of BSODs culprits, I'd suggest you to have a look at your memory, the sticks. Through decades people have been using the bootable tool called Memtest86+ and it's basically very unique in these manners.
Be sure to check your warranty rules and regulations before opening your case.
* Memtest86+ is USB-ready, and can be booted directly from it. Download the flashdrive wizard.
* To ensure that either your sticks OR your motherboard slots are broken, it's necessary to do the below procedure-
* Pull out all sticks except ONE, scan it.
* If no errors, pull the scanned stick into another slot.
* Proceed like this until you've scanned all sticks individually, and all the slots.
Best Regards,
Frederik.

Back in Januaury I ran memtest for 10 passes each stick/slot. It tested ok. Is there any chance it could be an intermittent problem with the ram slots themselves? I have long suspected the motherboard is screwy with this pc. What I really wanted to rule out was having to do a clean install of windows. It doesnt sound like that would help. Thank you again for your help

You can do the procedure I told you about earlier. Said in short, you pull out all your sticks except one, scan it. Pull it to another slot scan it. Proceed to all slots. Grab a new stick, test it in the first slot, proceed to the second and so on and so forth. By this, you'll have an answer if your slots or sticks are failing.
Slots failing is rare, but it happens.

Instead of doing a Clean Install, you can dual boot with Ubuntu from your USB stick, without installing it on your drive - which is clever.

Ubuntu
For a trial, try downloading a copy of Ubuntu and see if your system will crash.
By that, we'd have an idea if Windows 7's drivers and system is broken. You can try it out on a
flash drive if you so desire.
Go to Ubuntu.com | Download the image | See how to create a bootable flash drive
Leave it running for some time and report your results.

Best Regards,
Frederik.
