Windows 7 64 bit does not detect keyboard....

I beg to differ, my mobo bios has the choice of 32 bit OS, or 64 bit OS. His might not, but asking ?'s might jog him to something that works. I had too enable USB keyboard functions from the mobo bios. When I first put this system togather, I used W7 drivers for chipset. W7 should have had all the drivers he needed, maybe not the best ones but.......................

Make sure you have latest mobo bios installed. Try enabling everything in bios. Turn legacy bios off???????
Make sure you are looking into all bios options. Try only S1 state?????????

That option only enables the x64 instruction set in the cpu. His computer already has that enabled, or windows would have thrown an error before setup ever started. Enabling the usb keyboard only works for non-PnP aware/non-USB aware OS's. Its a workaround, windows 7 will not accept hardware to be presented to it in this fashion.

In some cases, windows drivers don't work. I've had a optical drive disappear from a windows 7 system, due to a microsoft driver update. Most of the time MS has good drivers with win7, but not always.

S1 vs S3 only affects the computer once it has already gone to sleep, not while its running.

The keyboard works fine in the bios, that means its a chipset driver issue. Once the computer has completed the POST, it hands over control of the system to your OS. Windows accesses the usb devices through the chipset driver.

Just looked at intel's website. A new bios Rev was posted last month. It corrects an unrecoverable buffer overflow error in usbhub.sys. I would try flashing the bios.

Bios:
BIOS Update [KGIBX10J.86A]
