ASUS P4R800 and PS2 keyboard problems

i've got a ASUS P4R800 mobo (radeon 9100 chipset), celeron 2.6 running Win XP Home and its got a wierd KB problem. it loses the kb in windows, it stops responding. if i remove the KB in device manager and reboot the KB starts working, but after a resart i lose it again. the KB works fine in BIOS. at first i thought it was a bad KB or a bad PS2 port, but it does the same thing with a usb KB. so windows problem? its all updated on a fresh winxp install. i've installed the latest mobo drivers from ati but nothing works. any ideas before i send the board back?

the kb ever work before ?

I didn't know ATI made motherboard chipsets.....

I had a client with a similar problem a few months ago, it turned out to be that accessibility options were enabled, go into the control panel and accessiblity options and make sure sticky keys or none of the other options are checked.

i found my problem, its the Microsoft KB831167 Patch. after i apply that patch my keyboards stops working (yes i've more than one usb and ps2). i do a system restore to before the patch and my keyboard works again. the patch is a IE 6 patch. anyone hear of anything like this?

I had a problem like this when I was setting up my new super computer recently. It turned out that I had the kb plugged into one of the legacy USB ports. It worked on the USB2 port, but not the legacy one. Strange. Heh,.. keyboards these day. Very picky I tell ya. Anyway,.. I ended up resolving this whole issue with a mobo firmware update. Asus rules! :)
