I have a really weird issue. The problem is when startup my PC and windows loads the mouse and keyboard which both have p2/s connections they don't work. However there are details to this:
The Keyboard works in the Bios.
The Mouse works when I windows 7 is starting up i.e. before I get the login screen.
When I plug an usb keyboard and mouse all its fine by the p2/s ones don't work in windows.
I have reimaged by pc several times still no success.
