Windows 7: BSOD during startup, "BAD_POOL_HEADER".

BSOD during startup, "BAD_POOL_HEADER".

I recently reinstalled windows for the first time since I bought this computer from it's previous owner. I installed a legitimate version of Home Premium, instead of the pirated Ultimate version that was on it before. I also installed it to a different hard drive.

Now I get a BSOD almost every time that I start up. It happens during boot, before the login screen. Says "BAD_POOL_HEADER". I'm on Windows 7 Home Premium 32bit. I've already updated graphics drivers to the latest version. Minidumps and other relevant files are attached. Thank you for your time

There seems to be a corrupt pool header, which is usually related to drivers causing buffer overflows.

Are you able to boot into the computer at all?

Hello and welcome to SF .

Your bugchecks appear to be caused by a very old WLAN driver.

Code:
BAD_POOL_HEADER (19)
The pool is already corrupt at the time of the current request.
This may or may not be due to the caller.
The internal pool links must be walked to figure out a possible cause of
the problem, and then special pool applied to the suspect tags or the driver
verifier to a suspect driver.
Arguments:
Arg1: 00000020, a pool block header size is corrupt.
Arg2: 86629000, The pool entry we were looking for within the page.
Arg3: 86629180, The next pool entry.
Arg4: 18300000, (reserved)
We see a usermode program calling into the kernel and using ndisuio

The raw stack doesn't reveal anything concrete as well, but by association of ndisuio (NDIS-uIO)
we can look at the active network related drivers.

This USB adapter is active:
Code:
Product Type    ZyXEL G-202 Wireless USB Adapter
Using this driver:
Code:
Driver    c:\windows\system32\drivers\wlangzxp.sys (1.7.3.38)
The driver is as I said is very old!
Code:
lmvm wlangzxp
start    end        module name
97a1f000 97ad2800   WlanGZXP   (deferred)             
    Image path: \SystemRoot\system32\DRIVERS\WlanGZXP.sys

I'm assuming you're able to boot into the PC long enough for you to post
this thread, please use that time to update the driver.

Yes, I'm using it right now. If I restart it enough times, it eventually will get to the login screen and work perfectly after that. Also, if it helps at all, it boots up every single time if I use safe mode.

I might be screwed then. Those drivers are actually the newest ones on the website. I bought that wifi adapter somewhere around 2004. It worked fine on my last windows 7 install. They are said to be compatible with 7 on the website.

EDIT: It looks like Zyxel has multiple driver pages. The last one I looked at only had the 2008 drivers. I will update those and report back if I have problems. Thanks!

Ok, Zyxel is doing something stupid. I downloaded what were labeled as the 2010 drivers, but windows told me that those weren't any more current than what I already had (2008).

So, out of curiosity, I read the .inf file in the new drivers I downloaded. They appear to actually be the same driver version I already have, from 2008.

WTF Zyxel? Is this some kind of joke?

When you do please post a new instance of the MSINFO32 file .

In MSINFO32 go to, File> Save> name it your user-name and upload.

I can't update my drivers, windows won't let me since the drivers I just downloaded seem to be identical to what I already have, despite being labeled differently on the manufacturers website. I've attached a new MSINFO32 anyways.

Have you checked for Realtek driver updates?

I updated Realtek drivers to the latest version, but to no avail. I'm going to assume that it is the WiFi adapter's fault.

I've already purchased a new Ethernet cable to run wired internet to this PC, something I've been planning to do for a long time now. I'll just deal with the errors until I can uninstall that driver and throw that aging adapter out. I'll come back here if the problem persists after I remove the driver. Thanks everybody for your help!
