Mouse/Keyboard/USB don't work anymore after turning off computer

[ShaolinMilk]

Hi folks.

Yesterday night I turned off my computer by pressing the power button and now my mouse and keyboard do not work anymore(in Windows). I wanted to see if it was just the mouse/keyboard itself, but I noticed nothing detects when I connect a USB device. I tried plugging it in every port and it's the same. I thought it was a hardware issue, but now I realize that it is not.

I restarted my computer and tried to get into safe mode; it worked(I was able to go up and down to select which mode I wanted to enter). Once inside safe mode and windows is loaded, the keyboard just freezes. It does not work at all. I then decided to go into bios to see what is up and everything seems right. I even screwed around and messed up my overclock settings.

So now I know my keyboard still works and it's probably a Windows issue. I wanted to see if my mouse would work. I went into Windows Repair(I might have gotten the name wrong) and voila, my mouse worked! I'm not sure if it's a virus or what not, but can someone kindly help me?

Thank you.

ps. I do not have any system restore save points unfortunately.

Hello once again.

I managed to find a ps/2 keyboard lying around and I figured out my problem. It was because I installed libUSB and it messed everything up.

That's good news. So I take it after uninstalling libUSB everything is in 100% working order?

hi, can you please elaborate more? because I'm also having the same problem with my keyboard, when entering setup before startup, keyboard works fine. After entering windows keyboard doesn't work, but some shortcut button does (like calculator, volume, mute, etc.)

where did you find ps/2 keyboard?
are you using usb port keyboard?

Hi,

My computer feels more unstable than before. I'm not sure what's up, but I'll have to look into it.

iksyaj: I have an old ps/2 keyboard lying around in my house and I found it. If it was a usb port keyboard, I would not be able to use it in Windows.

oh, I see.. I really don't have any idea how to fixed this.
Temporarily I'm troubleshooting the keyboard everytime I turn on my computer.
