The dreaded Blue Screen of Death titled Bad_Pool_Caller

I've started having this happen recently (within the last couple weeks or so).
I can run my computer 24/7 if I want and never have this happen.
However, there are two community/social oriented websites that I visit where I will experience this issue at what appears to be random intervals. I might get the BSoD logging into my account for the sites. I might get it after some extremely variable random period of time browsing the site. Or I might not get it at all.
These two sites are sites I've been visiting for a long time, and never had problems with before a couple weeks ago.
And again, I can surf the net all I want and never encounter this issue on all the other sites I visit, but these two I do.


Any preliminary thoughts? The only thing I can come up with is that there's a potentiality that around the time this issue started Adobe Flash Player updated to version 11 from 10. I can't be sure sure that these things line up perfectly but it's the only thing that even remotely comes to mind...but if this were the case, why only two of X number of regularly visited sites causing the problem?

The problem is pretty generic, does it contain a driver name, or was any software installed or removed during your last session that could have caused this error? has there been any recent hardware changes to the PC, particularly related to memory? Please provide more details about your machine so we can get a more clear view.

wifi driver issue? I still can't figure out why it would only happen on select websites.
Went into the event log and this is what was happening at the exact time of the crash.

In the security even viewer it shows 4 events at this time.
"An account was successfully logged on" followed by "Special privileges assigned to new logon."
The same two events repeat making the 4 total.
There are a crap-load of these events in the list that don't correspond to crash times.

In the application section nothing is listed at the exact time of the crash but the last thing before the crash was some software security stuff. "The Software Protection service has completed licensing status check." plus other events related to this protection service. It looks like these events were the last events before a previous crash this morning as well.

In the system log at the exact time are two entries
"The Multimedia Class Scheduler service entered the running state."
"The Windows Event Log service entered the running state."

I have not/did not update my wifi drivers so they shouldn't have changed. I'll run that next step and repost. Thanks

[rshaffer61]

OK that next step will let us know if the Wifi drivers are out of date so we can then update it.

[Steric]

I can't get the utility to run on PCpitstop. I tried all their general troubleshooting tips and still can't get it to run...lol

...and I was in IE

OK we can do it a different way. First is this a laptop or desktop?
Is it a brand name system and if so what make and model is it?

Download DriverMax and have it scan your system. It will open their website with all the out of date drivers you can update. With the free version you can update only 2 drivers per day so if you have a lot of them it will take a few days to get everything updated. I have been using it for about 4 months now and like it better then any other utility out there for keeping my drivers up to date.
If you want you can post screenshots of all the drivers in the list that need to be updated and I will suggest in what order to get them.

[Steric]

Ok here's the list...there were a handful of USB drivers at the bottom of the list that were green lighted as up to date that I didn't include in the images. I think I can kinda see the direction this will take based on what's supposedly outdated lol

OK the first two I want you to get is the Yukon and the Realtek ethernet controller drivers. Those two should take care of wireless issue.

[Steric]

Updated those two...everything appears to be good.

[rshaffer61]

OK test it for a few hours or even a day and see if the BSOD shows up again. If not then you can start updating anything else that is on the list if you would like to. If not then uninstall Drivermax and update me then. Good job and I will wait for your update.

[Steric]

Haven't had a crash since, thanks for the help!

[rshaffer61]

24 hours and no crashes...that is good news for sure.
We will wait at least another day and if everything is working correctly and you are happy then we will consider this topic resolved.
