Windows 7 not recognizing Arduino Uno on USB/Serial (or at all).

-

i've been working on arduino project , had arduino uno w/ wifi shield connected windows 7 computer via usb.
i able send sketches arduino, open serial monitor , watch output arduino without difficulty.

i use arduino stack on macbook pro , jump between 2 computers (the win7 stays home, , remote desktop modify sketches , check temperature readings via serial monitor).

a few days ago, arduino got wet while still connected windows 7 machine , both powered up.
i able clean arduino , wifi board successful , removed corrosion isopropyl alchohol. connect macbook pro's usb port, , able push sketches arduino, view serial monitor , successfully.

however, when connect windows 7 computer , open arduino ide, arduino not getting detected. serial port selection in tools menu greyed out. have since reloaded associated drivers, , uninstalled , reinstalled ide using unified installation posted forum.

the windows 7 machine still unable talk arduino.


did usb cable wet?
