Good afternoon ladies and gents I really hope someone can help me out as I am out of ideas myself. I will post the specs below but essentially, My computer has worked fine with all USB wireless keyboards and even a perix touch pad for over a year on windows 7. I recently downloaded the windows 8 update only to find that the perix pad now no longer seemed to work. I bought myself a lovely new b.unlimited M85-26000 wireless rechargeable keyboard and mouse by a company called cherry hoping this would solve the issue however the keyboard and mouse work perfectly in bios but nothing happens at all when windows 8 loads. I have tried every single USB port on my computer, with legacy turned on and off, the motherboard bios was updated just before the windows 8 install, the keyboard itself comes with no specific documentation or driver cd. Please help me get this resolved!
