Keyboard always stops working

Hi everyone, so I'm having a big problem. My keyboard was just fine few days ago, but now it stopped working, it's really annoying because I have to you desktop keyboard or what it is. Sometimes it works for a moment, but suddenly windows starts to show that usb device not recognized. Anyway, I searched for the solution for my problem many times. I tried to re-plug in my keyboard, shut down pc and turn on again, I also tried to search for drivers, but then it showed that there isn't any drivers, I tried to up to date them, but it's already up to date, I unistalled drivers and turned on pc for drivers to be installed again, but it showed that it failed. And ethernet controller, SM bus controller and universal serial bus (usb) controller are with yellow thing near to them, all the time (control panel>device manager>other devices). My other devices plugged in with usb work just fine, but keyboard doesnt do it at all. Can it be the problem or something else, or i just need to buy a new keyboard? Please help!

It sounds as though you are using a USB keyboard? It is not a wireless keyboard is it? Did you try plugging the keyboard into one of the other USB ports for which the devices are working instead of the same one which is not working? Did you run Windows Update to look for drivers? Do you have internet access on the machine still or is it not working due to the Ethernet controller problem? If you have access, and if Windows Update doesn't get you the drivers, you might try IOBIT driver booster free if you are having trouble installing drivers. It will look for missing drivers and will update them for you.

I have a usb keyboard and I tried to plug it to other usb inputs, but it still doesn't work and I also have normal internet connection.

But before, about all year my keyboard just worked fine without those things, buy I'll try them too.

Well, my keyboard is working now after IObit drivers updating, but still ethernet controller and universal serial bus (usb) controller are with yellow things near to them and sm bus controller even gone now. I hope my keyboard will work all the time from now. Thanks for helping guys :)

Hi Welcome to Seven Forums .... You need a Chipset and Earthnet Driver ... They can be found in the Link below ..

Well I can see chipset drivers, but no earthnet :/ I will surely download them if my keyboard start not working again. Thx
