At first it happened when I would click the minimized Google Chrome window to bring it back up. Now it happens randomly, or so it appears. I'm not new to computers and computer repair, but the circumstances appear vary from crash to crash. If anyone has any ideas, could you please share?

P.S. As a side not, to fix the BSOD on Chrome window, I rolled back my video drivers and it fixed that, yet it still appears to happen randomly.
Also, my sfc /scannow was clean and my drivers are all good and up to date except graphics drivers as the newest drivers for my GPU cause an issue.

Hello Connor, and welcome to Seven Forums.

Please read the instructions here: Blue Screen of Death (BSOD) Posting Instructions, and post back with the needed information. One of our BSOD experts should be by later when able to further help.

When you upload the dump files I will take a look.
But until you upload them there is not much we can do to help.

 

[Connor1186]

Unfortunately it says Invalid File when i attempt to upload it.

Click on it ....



It will download the DM log collector. Right click on the application and run as administrator. It will generate a .zip file on your desktop. Upload the .zip.

Sorry, hadn't had time to read the posting instructions, got it now. Thanks for being patient with me.

There's little useful information. Can you please enable driver verifier by following these instructions.

crashed on start up, couldnt boot with verifier running. tried several times. "A problem has been detected and windows has been shut down to prevent damage to your computer."

"The IO manager has detected a violation by a driver that is being verified. The faulty driver that is being verified must be debugged and replaced with a working version."

how would i go about locating and fixing the faulty driver? i have all of the information that was displayed but im not sure if it's useful.

Can you boot into safe mode? If so upload the dump files and go to start, verifier.exe then delete all settings.
You will have to do a system restore from the advanced boot settings (F8). Then you'll have to go onto the start menu, type "msconfig". Then go onto boot and untick all startup programs that aren't your AV.

And yes, it is very useful, driver Verifer has located the driver that's crashing the system (hopefully), it should tell us in the .dmp files.

 

[Connor1186]

problem is, i was able to boot up right after by using "use last known good configuration." but no actual dump file was created, or its not where it should be. and as for msconfig, it is set up with selective boot, as it has been for the past year, and nothing starts except my graphics drivers, Microsoft, and Dropbox. but without a dump file how do i find out whihc one is having a problem?

 

[Thedoctor44]

Sorry I made a mistake, it's not the boot option, it's the startup tab. Please disable all unnecessary programs except for your anti virus. The reason why the dump file wasn't saved was because you loaded the computer to a point before you even enabled driver verifier.
Can you enable Driver Verifier after you've disabled the startup programs.

Followed your instructions, disabled the last couple startup programs I had, I enabled driver verifier, and tried to boot, no good, then I tried safe mode, still no good, no option except to boot from last known good config. but when loading in safe mode, it would get hung up on classpnp.sys file, then reboot itself...does that mean it's that file?

 

[Thedoctor44]

classpnp.sys is the plug and play manager which manages all devices. That doesn't really help us.
Hmm. And no, it's definitely not that file. That is a critical Microsoft OS file that should never be modified or deleted. That is not the root cause, there is another driver that's causing problems.

 

[Connor1186]

Any more steps for me to try?

 

[Thedoctor44]

Disable Driver Verifier, then enable it again by following the instructions but this time when you enable the drivers make sure you don't select any drivers for Microsoft Cooperation, Unknown or Macrovision

Tried that, same result, no .dmp file and I cant boot in safe mode. any other troubleshooting steps I might be able to take? side note, I got another page fault bsod when opening my chrome window to save the opened pages. but no .dmp file was created. any ideas?

 

[Thedoctor44]

Hmm, from my experience page faults are generally created by faulty RAM. I would highly recommend running memtest86 for at least 8 passes.
Follow these instructions.
