Windows 7: tdx.sys causing BSOD - Fixed!

31 Jan 2009   #11

Windows 7 7000 32-bit


Just found you guys and this thread. My AVG 8.0 updated this morning and now I get the tdx.sys BSOD every 5 minutes or so. It's the ONLY update that has been done to this computer in the last 24 hours. Win7 has been rock solid up to this point.

I am running on a 780i chipset board with an nVidia NIC.

Windows 7/Vista

Hi guys,

I thought I'd sign up to try and help since I was havin a bsod with that tdx.sys ever couple of minuites

Try following this and see if it works for you:
Why can't I access my NAS (Network Attached Storage) share, Macintosh (MAC) share, linux share, or a share from an old version of Windows

after following that I haven't had a bsod since with tdx.sys and thats with AVg running smoothly

Windows 7 beta
still BSoD

Hi, tried it all but it did not help.
I'm runnig Win7 on a DELL inspiron 1525 with a Marvell Yukon networkadapter. The problematic part ist my NAS: d-link DND-323. If I turn it on, I get the bsod after about 5-10 minutes. Firmware of NAS is uptodate. Driver ofe networkadapter dito. What can I possibly try?
Thanks for any ideas.

Windows 7 64bit / Vista 64 / Vista 32

Same issue here with Win7 64 bit, Avast antivirus and Nvidia 680 chipset with 2 Nvidia NICs
However, it only happens when I have mapped network drives from my synology NAS (DS209+, with firmware DSM 2.0-0731).

It happen with in 10 minutes everytime I booted up Win7,
but after disabling my login script, it haven't made a BSOD since

In Vista 64, I never had this issue

Windows 7 Beta build 7000
BSOD tdx.sys issues

I seem to be encountering my own share of BSOD issues relating to the tdx.sys file. Unfortunately, they occur withing about 5 minutes or less, so there's not a lot of time to dig deep into what's happening. Additionally, whatever is happening doesn't seem to require that I even be doing anything with the computer at the time. Sitting idle is enough to cause the BSOD.

The computer in question is an HP dv9005, upgraded to 1.5 Gb memory, with an AMD Turon 64 x2 processor (1.6 Ghz, I believe).

I would love to get a chance to try out Win7, but so far, I've barely gotten a chance to see more than the desktop. I'm almost considering a reversion back to Vista (which ran really slowly, but never went to BSOD on me), or even further back to XP.

Windows 7
tdx.sys BSOD issue

I am dual booting between XP and Windows 7 build 7000. (32bit)
My System is a dell Dimension 4600 with a Intel Pro 100 VE Network Card. I am also using a NAS (DLINK NAS 323) connected to my Router and My pc connects to the network using a cable (not wireless).

Recently I started getting bsod and I have tried reinstalling the windows 7 fresh and still no use. I was having this BSOD every few minutes. Then I read this forum and disconnected my NAS drive mappings and the BSOD disappeared. But If I am working on any files from my NAS I still get the BSOD error. I am using Avast home Anti virus. My NAS firmware and drivers are updated. I have also updated the Intel network driver. If anyone finds a permanent solution for this issue please post it here.


I think I got it under control now. Basically I un-installed Avast and reinstalled AVG Free. (Initially AVG gave me issues with online updating, but after a reboot and restart of Modem and router it fixed though). No BSOD in the last 2 hours. I have mapped the drives and it looks good.

Windows 7 x64 RTM

Update: BSOD with TDX.sys returned after changing antivirus to Trend Micro :-(

Going back to Avast for now but this is annoying. I have also tried several NIC drivers and do not have VMware installed anymore.

Windows 7 Beta

Some detailed information:
Usually happens when acccessing NAS and if some other firewall is installed than windows own or other application that can control network (use tdx.sys).

Now I use Avira Antivir, Windows Firewall and Windows Defender without BSOD problem of tdx.sys

I have tryed these Antivirus + FW + Internetcontrol softwares.
- Norton
- F-Secure
These all had BSOD tdx.sys problems

That was it indeed - I removed NORTON 360 and now the NAS is running as it should. What antivirus solution would you recommend? Would not like to spend hours installing and removing..... As far as I could take it from this thread, Antivir seems to be the only nonproblematic program. Is that so?
