Keyboard and Mouse work in BIOS but do not work in OS

My graphics card was having issues with windows 10, so I used my windows 7 disk and installed windows 7. After the installation process occurred, my mouse and keyboard were unresponsive and not lit up. I finally managed to get into my bios and I don’t really know what I did, but it turned my keyboard and mouse back on. Then I did my 192 windows updates and installed my graphics drivers.. once I finished installing those, I restarted my computer to finish the updates and i came back to my computer on my desktop and my keyboard and mouse were not responding. Then I went to my bios and made sure my settings were defaulted and still nothing has happened.

Motherboard: MSI b150a Gaming Pro

  1. Are your keyboard and mouse both USB or PS/2? The problem is probably your USB drivers in Windows.

  2. The MSI b150a Gaming Pro its a usb issue, that motherboard is suppose to have windows 10 running on it. You can try the usb under the PS2 port, if that doesnt work then find usb header cable and plug your keyboard and mouse directly into the USB 2.0 header on the motherboard.

    if all else fails find an old PS2 keyboard and plug it in, the ps2 port should still be working and you can install whatever drivers you need to get the usb 3.0 ports working.

    I found out from an IT staff that the problem is driver based. I need to figure out now how to install a exe file from my flash drive before I log on. If you know anything about that any help is appreciated. Thanks for your time.

  5. If your mouse and keybd are already in the usb2 ports and win7 is not running them with the default drivers you have a few possible issues.
    You may need to try using basic/cheap usb keybd and mouse in case you have gaming ones that also need drivers before they can work.
    Another could be that win7 does not have basic drivers for this newer usb2 chipset and you will need to slipstream them into the 7 install.
    Win7 will definitely not have your USB3 drivers so be sure to install all your motherbds drivers from the link I posted on your other thread. This is also why you should be plugged into USB2 ports until then.

    I install drivers in the following order: Chipset, Graphics Card, Network, USB, Sound, and then anything else. Reboot when prompted too.
