What happen to my Hp printer? It always says that it is not connected but the USB chord is brandnew, is there any advice that you can give ?

Hi Gurus,

My modem was working perfectly fine when just a while ago I got this error message.  I haven’t changed nor touched the SIM inside it and so I wondered why I got this error.  

Need your help as I couldn’t connect to the internet and still have to go to an internet café.  I wouldn’t want to buy a new one since this modem in error is fairly new.  

Please help resolve.

Only the specified SIM/USIM card be used on the device!

Hello,

There has been a recent problem relating to sound. I have set the sound levels at max. But there is no sound at all. I cannot understand whether this is a problem with the settings or it is a problem with hardware or speaker device. For you information I have done any operating system setup either. Kindly someone help me get me out of these problem.

When I connect a USB device with front side of the CPU, I cannot access this device. But I see the confirmation message of USB device recognition in the notification area of Taskbar. On the other hand, when I use back side of the CPU for the same USB device, it works perfectly. How can I make the CPU’s front side workable for USB Devices?

When I press the Eject Button of my computer’s DVD-ROM Drive, it opens a bit and closes again automatically.

Now it became useless.
