After upgrading our desktop from Windows 7 Ultimate 64-bit to Windows 8.1 Pro 64-bit, I sometimes get weird characters shown as I type. The gibberish superimposes briefly on the last few characters only, then switch back to the normal characters. Additionally, FF hangs quite often. Not sure what causes it. Any idea?
