Hello everyone,

I updated my Windows 8 to Windows 8.1 tonight and unfortunately had a BSOD when trying to boot into the new 8.1 for the first time.

I attempted to fix the booting issue with my Windows 8 recovery disk and it said it couldn't help.

Anyway, I fixed it by powering down the computer, unplugging all USB cables accept the mouse and keyboard and then turned the computer back on. I booted straight into Windows 8.1 without any problems.

Once at the desktop, I started to plug in my usual USB devices (Mix Amp, G13) and found that my keyboard had stopped responding, so I unplugged it and plugged it back in only to find my mouse has stopped working but my keyboard is fine. So I did the same to my mouse and now all devices are working again.

Thought this process might help some people out.
