Solved bsod bad pool header - netgear driver

[rkcrusha]

Hi Folks,

Thanks in advance....

I read all the solved "bad pool header" posts and couldn't find this specific issue, so I was hoping someone could help.

I recently purchased a Netgear A6210 wireless adapter and ever since the first time I power on the PC it goes to bsod straight after windows screen in startup. However when I switch pc off and restart in normal mode it starts (it does take longer than normal).

I have done system restore and without the netgear driver the system runs fine. as soon as I re-install the problem re-occurs.

I have done mem tests, removed ram, updated windows, updated all drivers, tried all 3 drivers for A6210 from Netgear website. Strange thing is everytime I try something new the PC tends to start 1st time but then I come back the next day and its bsod again.

One other strange thing I noticed was when I tried to uninstall my old Belkin wireless adapter it came up with a message saying "uninstall unsuccessful - unable to uninstall setup.exe"

I'd really like to keep the netgear adapter as my network speeds are awesome so I was hoping we could find how to resolve the conflict rather than ditching the adapter.

Hello, rkcrusha. I will try to help you with this error. Many of your dump files could not be opened, for some reason. All of the ones I did open said the same thing:

That is the Etron USB 3.0 Extensible Host Controller Driver And can be downloaded at the Asrock Site for your Motherboard, (ASRock > Z68 Extreme4 Gen3). As you can see, the driver is pretty old. It does name your Netgear, but does not blame it. Try updating the Etron driver and see if your results improve any. I would also unplug anything plugged into the USB 3.0 ports, if possible.

Hi Essenbe,

Thanks for your help.

You were spot on, there is certainly conflict between the netgear & usb 3 host and pondering back I don't think this is the first time I've had issues with my usb3 and devices.

I did what you said and re-installed driver and started the pc with nothing in usb3 and "bang" bsod again.

I had a quick think and asked myself, "do I really need the usb3 ports?". So I tested network and internet speeds via usb2 and with desktop extension cable attached to netgear my speeds were actually faster than before.

I then uninstalled usb3 completely, restarted and the pc was back to normal. repeated process 4 times and all good.

It does eat at me a little knowing I have 2 ports on the front of the case that don't work, but no more bsod is a pretty good trade off.

thanks again
