Computer do not normally sleep wake up and the computer hang when external USB devices are connected

Hello

I have a Windows 7 Home Premium 64-bit desktop CyberPowerPC, and there are currently two problems with it:

1.), I have two USB ports in the front of my case. I am connected to my computer. Then I tried to connect my external hard drive using the USB cable supplied with it, but just at the moment where the end of the USB cable touched the port, the screen is black and automatically rebooted and froze when the display shows the brand CPU that is before the login screen. I actually press the restart on my case button to restart the computer with the hard drive already plugged. Then everything should work normally.

It's the same thing when I tried to connect my iTouch 2nd generation.

This problem occurs sometimes, however, but I wonder if someone always has a solution to this?

2.) whenever I put the computer to sleep and he remains asleep for a while and I turn it on it once again, powers for about 2 seconds then it turns off. I have to turn the power supply and light in the order so he could get out of mode 'sleep'.

I was wondering if you have solutions to this problem, as well.

Thank you.

Original title: new Windows 7 problem

Ok.. I'll try again...

The problem is caused by a bad 'ground' between the USB ports of the case and the motherboard. Static electricity is originally the USB device to short on the USB port which is originally the motherboard restart mode.

I had the same problem and got my computer case exchanged. The problem has not entirely disappeared, and I use the USB port on the front on the card reader, just in case.

It can also be a problem with the power supply or even the motherboard. It is very difficult to locate the failure without replacing in turn, a process that happens to be a bit expensive.

The above is the reason why I recommend that you contact the MANUFACTURER. Don't take no for an answer off the manufacturer or supplier. It is a problem annoying which can eventually damage your operating system if it is enough...

  • Windows Vista Ultimate Edition started cutting the computer when certain usb devices are connected

    I had this platform for a few years with no problems. Last week when I went to sync an ipod (which I had already done several times) it abruptly shuts. I can it restarts, but when I try to sync the ipod, same thing happens, no error message full closed.  Also, I noticed that when I am attaching other devices such as an external hard drive or a blackberry it stops.  Today, he does even without fixing anything. All of these devices were working very well.  I have disassembled the computer, cleaned all fans, removed all dust bunnies. I have an ASUS MB, cpu temperature seems good. I think it's a software/driver problem. The thing is I have not installed anything, System Restore does nothing, all the usb drivers say they are up-to-date. All USB ports are affected, even most directly on the MB.  Anyone had this happen?  I think buying windows 7 and try it because I don't want to replace the motherboard, I spent $$ on this a few years ago, raid, etc. of liquid cooling.

    It should last me awhile longer, last year the food out crapped (dust bunnies blocked fan), I replaced with a 1100 watt tagan. This system had worked great for a year, so I don't think it's a matter of P/S.

    Any help or advice would be greatly appreciated!

    Hi Highrever,

    1. do you have the latest Vista service pack installed on the computer?

    You can try to uninstall and reinstall the complete USB hub drivers and check.

    a. Click Start and typedevmgmt.msc and then click OK. Device Manager opens.

    b. expand Bus USB controllers.

    c. the first USB controller under Bus USB controllers right click and then click on uninstall to remove it.

    d. Repeat steps above for each controller USB is listed under Bus USB controllers.

    e. restart the computer.

    You can also check if you get special material related errors in Event Viewer about what is causing the problem.

  • ProBook 4740 s will not feed if USB devices are connected

    G ' Day, I have a ProBook s 4740 and after taking the laptop to the site, when I'm home and plugged things back, by pressing the power button would see it for a few seconds and then od light out. The LED above the power would have flashes once and then turns off. Needless to say, it would not start up.

    After a lot of frustration, I found that by unplugging all (wired Ethernet and USB devices) and by pressing the power button it would start up and even when starting I could plug the devices and everything is OK.

    I had to return to the site today and when I came back again, it wouldn't power up until I unplugged the USB devices. USB devices are external hard drives only, all running through a powered USB hub.

    This configuration has worked without any problems for wells in the year I've had the ProBook.

    This could be the cause?

    Thank you.

    The last update :-)

    After downloading the BIOS update, I decided to wait until I had a break in things until I applied it. Then around one hour before, I saw the red exclamation mark on the HP Support Assistant in the taskbar. Open it, there was an update of the available BIOS, so I decided to let him do. At this point, no indication that it was the F.60 update.

    I hate doing these updates that work at the machine code level where if things go wrong, they can go horribly wrong.

    Well, everything went well. Updated the BIOS and restart the computer. I went back in to the support assistant and got the information on the computer, and he says that it is now the F.60 version. If she went from F.43 to F.60

    I power it off, wait a minute, then restarted with everything plugged in and it worked correctly.

    Thanks again for your help.

I bought a new webcam installed and everything went well, and exactly the same thing happened. (microsoft livecam this time) no sound. Anyone have any ideas?

    Hi Johnny,.

    Perform the System Restore to an earlier date and check if it helps.

    System restore

    System Restore can return programs and system files from your PC to a time when everything was working well. This will not affect your documents, images or other data.

    Hope this information helps.

    I have found a more permanent solution. At the command prompt, type Diskpart

    type

    If the answer says disabled, type

    automount enable

    Once I did, my USB keys have been recognized automatically when it is plugged.

    Why the setting has been disabled? who knows.
