I have a new ivy bridge setup with an Asrock Z77 Extreme4 mobo. Every time I want to enter BIOS I have to bring out my old ps2 keyboard again. The weird part is that all the usb drivers are installed, and I can use my mouse in BIOS but not my keyboard. Ive tried switching from the usb3.0 and 2.0 slots with the same results. Any help is much appreciated.

You're lucky, I just put the same combo together yesterday and when I booted it up for the first time and got in the UEFI setup, my cursor floated around the screen and when I tried to move it , it would dart back to the center of the screen. I loaded windows 7 and installed all the drivers for the MB and updates from microsoft I went back into the UEFI and the cursor was only 50% better.

In the UEFI I clicked on advanced and mouse USB power was disabled so I enabled it also PS/2 keyboard was disabled so I changed it to any key ( I have a microsoft wireless keyboard with both PS/2 and USB connection, so this would free up a USB port and I use a USB microsoft mouse).

I exited the UEFI and shut down the computer unplugged the keyboard from the USB and plugged it into the PS/2 booted back up and let the computer go right into windows , windows recognized the PS/2 right away and installed the driver. Then I went to the microsoft downloads and downloaded the latest driver for the mouse, windows did not install the latest driver in the setup or the updates I had to do it myself. I went back into the UEFI and like magic both the keyboard and mouse functioned normally. I'm not sure if there was just one of he things I did or the whole combination but it,s working now.

I wish i only had a keyboard problem. When overclocking I am experiencing freezing on the CPU OC screen. It will freeze and I cannot go anywhere else. If I go to a different screen it works fine but when overclocked and when I am on the main oc screen it just freezes.

The OC Screen of the UEFI BIOS. There is a tab that says OC tweaker I believe.
