I installed Windows 2003 SBS on a Dell Optiplex GX520 last week. All was working fine until a couple of days ago. Since then, my USB keyboard has been acting weird. I can use some of the keys (Enter, NumLock, ScrollLock, CapsLock, Pause, Tab) but not anything else. The computer just beeps at me when I hit anything else. I've tried different keyboards but they do the same thing which is why I think it's either a driver problem or a virus or something like that. I've removed anything to do with USB or keyboards or HID devices from device manager and had the OS redetect them but that did not do anything. There are no drivers for this on the Dell website for Windows 2003 so I attempted to install the Chipset drivers for XP and it still did not do anything. Oh, one more thing... when I hit <Tab> it scrolls through the different fields (i.e. Username, Password, Domain on logon) backwards (i.e. Username --> Options --> Cancel --> OK --> Domain --> Password).
What else can I try? BTW, I can terminal into the computer fine and the keyboard works perfectly from RDP.
