I have a Dell Optiplex with 512mb ram & 1.8 P4 - We used a Microsoft Wireless Desktop Elite (keyboard - PS2 & mouse USB & PS2. I upgraded the machine to Windows XP Pro - now, only the wireless mouse works on bootup. The wireless KB freezes & you cannot perform CTRL+ALT+DEL. The mouse continues to work but the KB is frozen & you can only power off. The same thing occurs under safe mode. Is there some glitch with Microsoft products under XP Pro Upgrade? I connected 3 different PS2 keyboards to no avail. Any suggestions??
