Win 7 USB drivers mouse and keyboard drivers not working

Win 7 USB mouse and keyboard drivers not working:
KNOWN GOOD mouse and keybd allow INPUT TO bios, and in thumb drive windows (HIREM MINI WINDOWS) session.

Green lamps on keybd are lit during post/ extinguish when Win 7 PRO starts.

How to gain access to OS, and what to do once in?

Booting into F8 world is no help....same business.

Thanks

Use a kb/mouse USB/PS/2 adapter, if you don't have a working PS/2 kb (I assume you only have a single PS/2 port).
Then delete the kb and mouse from device manager and let Windows re-install the drivers.

HTH,

check if keyboard and mouse is working on another machine ?

if not...........answer is simple

if working.........means there is some problem with USB ports.......
try front \ rear USB ports...........

Thanks

test first if it works ok when booted from a live cd, or bootable USB
here a nice live cd : ftp://mirrors.kernel.org/knoppix-dvd/KNOPPIX_V7.0.5DVD-2012-12-21-EN.iso

if it works in the bios - and not in the os - it looks like a driver problem
you can delete - or update the driver then

**are you sure there' no malware on the pc?
scan it with the offline defender, or Kaspersky cd :
