I can't use keyboard with Windows 7 Ultimate??
I had windows xp sp3 there was no problem but when i installed windows 7 i can not use my keyboard .I dont understand why, something like usb problems.In device manager seems no problem but i dont see any driver about keyboard.In control panel there is no keyboard options.When i push the power bottom windows starts normally num lock or caps lock keys are working until windows 7 screen comes.İ updated my bios i did lots of things but i couldnt solve.I had asus p4s800 mx-se mainboard p4 3.0cpu 1gb ddr ram sapphire 1950 gt graphic.
