Hi! I have a real problem going on with my machine. I have a Dell Studio 1558 with 8GB of RAM, Intel i7 Processor Q 840 @ 1.87 GHz (8M cache), 64-bit Operating System and ATI Mobility Radeon HD 5470 1 GB Graphic Card with Windows 7 Ultimate edition. Now, my computer use get shut down automatically with a blue screen error message. Initially I didn't have any idea what could be the cause of the problem, so I had Dell engineers changed the motherboard, cooling fan and thermal pad of the machine thinking that it might be some hardware issue but it didn't really help. I even installed a new fresh copy of Windows, formatting the whole HDD and that even didn't go for a penny So, after all the research work, I came to know about "Windbg" tool. I tried to debug the files that were left into the "C:\Windows\Minidump" folder. (NOTE- I've absorved that my computers only gets shutdown only after I try running Utorrent. It happens after sometime, when I try runing Utorrent). So, here is what I got as a result:- Microsoft (R) Windows Debugger Version 6.12.0002.633 AMD64 Copyright (c) Microsoft Corporation.

Update the Network card drivers. if this doesn't work, upload the dmp files. I look at them."A programmer is just a tool which converts caffeine into code" Want to install RSAT on Windows 7 Sp1? Check my HowTo: http://www.msfn.org/board/index.php?showtopic=150221

@ Andre :- Mate, can you please tell me "How to update Network Card drivers" 'coz as far my understanding I went to Device Manager, clicked on the Network adapters. Under it there were 5 adapters given as below:- 1.> Bluetooth Device (Personal Area Network) 2.> Bluetooth Device (RFCOMM Protocol TDI) 3.> Dell Wireless 1520 Wireless-N WLAN Mini-Card. 4.> Microsoft Virtual WiFi Miniport Adapter. 5.> Realtek PCIe GBE Family Controller. I right clicked on every single of these, then clicked on "Update Driver Software". As a matter of fact it says all are already up to date. Please tell me if I have been doing it in a right way or not? If not please tell me how to do that. Thank's in advance.Amandeep Singh Gill

Heah Andre, Mate, did exactly as you said, but it really didn't help. I've updated all the network drivers, but still the same. I've uploaded all the files. In every single file WinDbg shows "NetIO.sys" as a faulty file or driver. Here is the link, please have a look. https://cid-487a2d38f32825c8.skydrive.live.com/redir.aspx?resid=487A2D38F32825C8!149&authkey=0HQkrIMUozo%24 See, if you can do something about this please.

Seems the same thing with me Nori. I got the same problem after I installed Windows 7 service pack 1. Wonder what's wrong with this. Can't find the solution and what makes matter worse is that MICROSOFT says we still don't have the solution for this one.Amandeep Singh Gill

Download the Latest Network-Hardware drivers (maybe some are provided trough Windows Update? ) After installing the new drivers; open a command promt window (CMD) then type; sfc /scannow Reboot your pc when ready. If the problem still exists: Option One: Boot into Safe Mode (F8 during system start up), uninstall all the network hardware (LAN-Card and other adapters etc.) Restart now, and let Windows install them again ;) Option Two : Re-Assign IRQL numbers in BIOS (switch them around a little). That should do the trick most op the time ;) Wanna know what will be a good pc to buy? Create your own!

@ dutch_commander Dear, I was wondering, if you can walk me through, as to how to "Re-Assign IRQL numbers in BIOS, 'coz as a matter of fact I never messed up with these kind of settings in BIOS. So, really not sure, how to do it and don't want to take risk. Thank'sAmandeep Singh Gill

Completly get you there, i'll do my best ;) i'll get back to you ;)Wanna know what will be a good pc to buy? Create your own ;)

Thank's mate.Amandeep Singh Gill

well, i called a friend of mine who owns a Studio 1557 laptop (same BIOS design/layout/version), But he sold his one. So i can't give you any excact instructions. Luckly Dell offers an alternative; without looking in to the BIOS. It's located here: http://support.dell.com/support/downloads/driverslist.aspx?os=W764&catid=13&dateid=-1&impid=-1&osl=EN&typeid=-1&formatid=-1&servicetag=&SystemID=STUDIO1558&hidos=W764&hidlang=en&TabIndex=&scanSupported=True&scanConsent=False If it can't find anything, you can look it also up in Windows itself: Click on START, click on CONTROL PANEL. Click on System Click on DEVICE MANAGER/Hardware(-Management) (i don't know what its called in the English GUI) button. Once you have Device Manager open, select VIEW from the toolbar menu, and then click Resources by Type. Check if there are any conflicts; if so, you should call Dell in order to change the IRQ adrresses. If it doesn't work out for you, just enter the BIOS and look up the IRQ Assignments; change some especially the network stuff. When you find it too risky or Windows won't boot or the problem still excists; again enter the BIOS and choose for: Restore Factory Defaults ;) This is the best that i can do for you ;) Good luck!

Sorry for my bad English, I'm Dutch ;) :$Wanna know what will be a good pc to buy? Create your own ;)

Don't worry about the English part, my friend. Thnak's for writing in. Let me see it :-)Amandeep Singh Gill

@ dutch_commander Couple of questions for you mate. First thing in BIOS of Studio Laptops, there ain't any option of "Networking" or "IRO Assignments". Other thing my friend is that I just did whatever you asked me, but how can make out if there is any conflict in "Interrupt request (IRO)" in Device Manager? I mean all I can see is some numbers and (ISA) written everywhere. Any suggestions?Amandeep Singh Gill

P.S I've seen that all the number mentioned in bracket, they start from (00) then (01) and jumps to (08) then (12) following (13) then jumping to (20) and then all the way to (81) and then continuously without a break till (190). NO NUMBER IS REPEATED.Amandeep Singh Gill

I'm having the same problem when running bittorent after win 7 SP1. I also have a Realtek NIC. I was told by Microsoft Support that because it's netio.sys it must be the nic driver. I've been in touch with Realtek support that say it's a problem with netio.sys. This is after I upgraded to the most recent driver. The issue is with the large number of connections in bittorrent. I typically have it set to around 600 max connections. I don't have an issue (at least for many hours) when I lower max connections to 10 in bittorrent. I'm trying to find some kind of diag tool that will stressed test based on connections and not just send/receive.

As a follow up, I get BSOD after about 9 hours even at only 10 connections. This is the thread I opened for my issue: http://social.technet.microsoft.com/Forums/en-US/w7itproperf/thread/dab0cff0-0288-4c86-b66c-ad1e731b1e05/#d2d5e59b-26d4-40d4-be0b-52d89b0569e4

Turns out the problem appears to be with McAfee! I uninstalled and was able to run Bittorrent at high load for a couple hours.

Got the same problem (it happened when the Win7 machine get more then 9 connections to the computer, torrent, unc browsing) i stopped McAfee (Virusscanner enterprise v.8.8) and problem solved. Just submit a case in McAfee hopefully they patch is I've got exacly the same NETIO.sys BSOD messages after installing Win7 SP1 and running uTorrent. I've also got McAfee v8.8 Enterprise running, i'll turn it off and let you know how it worked out.

It seems that the same problem has started with Norton as well. I started having this exact BSOD problems with Norton right after I came back from a break yesterday, and noticed that there were multiple posts on several other boards describing the same problem in connection with Norton in the past few weeks as well. Restoring the system to the last version before I left town (early/mid December) seems to stop this, altho that can't be the permanent solution.... :/

just ket u guys know i rolled back the network adapter driver to orignal and u torrent wasnt causeing blue screen yes result
