Dell Gx270 running WinXPSP2. System recognizes USB mouse & keyboard in bios
but not when Windows loads. Tried boot to last known good config. From
restore cd, ran a chkdsk/r. Ran Dell system diagnostics and both devices
function properly. Each time Windows loads, get Welcome screen and no
response from either keyboard or mouse. Have tried all USB ports (front &
rear) with no response. Any suggestions appreciated and thank you in advance.
