Whenever I am in the process of shutting down Windows 7 and if I removed the USB modem(ADSL) cable, Windows 7 crashes with blue screen(some times system simply gets turned off without proper shut down).This happens only during the shut down process, If I removed USB cable any other time there is no problem. I've not tried removing any other usb devices during the shut down process. I will try later to see if this is problem only with USB modem or all USB devices.I am using HP 2133 Mini Note with VIA C-7 processor 1.2Ghz, 2 gb RAM. Has anyone else faced this problem? Please let me know if there are any fixes/workaround to this problem.

Hi What is the error message details on the blue screen? How are you removing the USB modem cable? Are you using the Safely Remove icon in the Notification Area? Let us know. Ronnie Vernon MVP

Why are you pulling out USB Cables as the computer is shutting down??????? Unplug them, "Remove Safely",before you start Shutdown. The System has its own orderly shutdown, which you are interfering with.

I am removing the cable physically, I am one of those impatients lads; I've removed cable similarly with windows XP machine there is no problem whatsoever.I know it is not ideal scenario for test, but I believe that a software should never crash if at all in any scenario. Thats a real sign of a stable software and stable operating system.I dont remember exactlly what was shown on BSOD as it was usual something unreadble by humans :)Hope this helps!Thanks for your interest and help.

Hi TanLoves7 I'm not sure why you would be removing the modem cable? Removing the cable is not the problem, the system can handle that, however the system requires that it be removed properly. This is definitely something that needs to be done properly, using the Safely Remove Icon that appears in the Taskbar or waiting until the system is completely shut down. The system can be as stable as a rock, but if something is intentionally done that affects that stability, then anything can happen. Regards, Ronnie Vernon MVP

Well, Thanks for letting me know how the device should be removed BUT point is not that!! Point is that Windows 7 crashes and Windows XP doesnt with the same device and with the same action!!!When windows is shutting down, why would I care using "Safely Remove Icon"?? It doesnt make sense either, for me I've started the shut down and I am not going to use that PC and I want to connect that device to some other PC why do i've to wait till the PC is shut down? I know I sound bit impatient and not following rules kind of person here, but my point is Windows 7 crashed and for silly reason like removing the USB cable! If i was doing something like removing harddrive cable or something I would have noted your point!!!Anyway thanks for your effort telling me how should I remove USB device!Cheers

So being an impatient, "not following rules" kind of person means that the OS is at fault? I guess that means if you throw your computeroff of aledge as it isshutting down, the OSshould be able to withstand the physical impact as the case and other components shatter. Likewise, the OS should be able to shutdown in an orderly way as you remove a memory module or any PCI/PCI-e card. There are proper and improper methods of doing things. A programmer just cannot use an improper method of declaring a variable or defining a class just because he or shedon't like following rules. Nonetheless, you are, or course, free to do as you please with your stuff. This is not a fault of the OS.

Have you ever heard of "Regression Testing"?? I guess you must have! Programmers do code following "Proper" methods, they test using "Proper" methods i.e. Happy Flow!!! When testers starts testing it, they consider all scenarios, "happy flow" and "Naughty Flow"!! You are suggesting as if i've removed the power cable or removed the hard disk cable and then i am compaling about PC stopped working! I just removed the USB cable, why should OS abnormally crash? I've never heard this case being with older Windows OS XP neither with Linux or MAC?As far as I am concerned there is a fault in Windows 7 which does not handle removal of devices properly during the shutdown! Programmer may not code improperly, but a good programmer must handle all exceptions! When exceptions are not handled the proper flow gets interrupted and program crashes!!!

TanLoves7: You have a legitimate question. Some peoplewait for the last light to go out and some don't.Because you get a blue screen you should be able to capture some details to submit in, say, a techincal forum. Paul

Hi TanLoves7, The best thing to do here is to wait until the system has finished shutting down. Then, remove the cable to avoid the BSOD. Then, before you turn your computer back on, re-insert the cable(s). Eventually,(hopefully),Microsoft will be able to fix this in time because I too would find it inconvenient to have a BSOF occur each time I shut down and remove a cable.Yes, I am here with you too ;-) I am impatient as well and I don't blame you. I always remove USB and networking cables from my laptop all the time. I hate having to bother with going to the Safely Remove icon in order to remove anything. I should be able to remove something when I want without it being screwed up. However, this is just a precaution to ensure that we don't lose any important files or stop a process right in the middle of it happening. However, I do also agree that W7 should not show a BSOD while removing a modem cord, partly because the network connections have already been closed on the logout! :D Hope this helps, btb42693

I get a BSOD (Stop Error) when I try to run the Windows Experiance. This is the error I got Stop: d0000144 Unknown Hard Error

Could it simply be down to incompatible drivers for the modem? I've heard of this issue before, even when unplugging cables whilst Windows is still running, and its usually down to older drivers been used. Has the modem manufacturer not got any Windows 7 drivers, or Windows Vista drivers that you could install?

If the sudden removal of a device (which is what ripping the cable out is) causes the driver to crash (the most probable cause of a BSOD) then it sounds like the device driver is not detecting the removal cleanly. That device driver may, or may not, be part of Windows. You say this doesn't occur in XP. Does it occur in Vista? The reason I ask is because Vista uses a different device driver model to XP. A copy of the BSOD would be useful (you may be able to find details in the event log after the system comes back up - otherwise, it sounds bizarre but can you take a photo of the BSOD?) but at the very least it should give an error code which looks a bit like 0x00000000 and the name of the failing module/driver. I agree that the rest is pretty inintelligable but it's not complete garbage! If you're able to post this information then we might be able to have a go at working out what the issue is. I'm not saying that it's you're fault for being impatient (many other people will be too!) but we do need to understand if this is a device driver issue or a problem in the Windows code. Finally, As BBFC-UK suggested, making sure you have the latest applicable drivers is always good advice if you are having stability issues.

TanLoves7: to find out the answer to your issue first we need to know some things first. Have you installed any drivers or are you using the drivers that came with Windows 7? What kind of computer are you using is it a home brew or a prebuilt IE dell HP or so on? What are your hardware specs? You know pulling the USB cable is not going to make your computer shutdown any faster. It could damage the USB hardware. Thats why you have the little icon in the taskbar to shut them down properly. You would probably be better off using the onboard NIC with some cat 5 cable to hook your modem to your computer. USB to network is not the best network data solution. Especially on older computers and if your computer does not have an onboard NIC it would fall into that category. The bsod your getting is a bad driver if you have installed any remove them and see if that works. Or give us the specs and that will give us somewhere to start so we can help you will your issue.
