I have been fighting this same problem for about 5 months.

I have the Wireless Optical Desktop 3.0 (Wireless Comfort Keyboard & Wireless Optical Mouse 2.0). Three or four times a week it stops working at random intervals. The driver DLLs simply disappear. I can see this by going to Control Panel -> Keyboard Properties -> Hardware -> Properties -> Driver -> Driver Details. The two dll files are there when it works and the dll files are gone when it stops, gone, no drivers at all. An old PS2 will still work in a pinch.

I wonder if the problem may be caused by my Windows Live OneCare or by a Windows Update that keeps reinstalling itself and failing. Alternatively, could it be that some malware is trying to gain control of the PC?

Reinstalling the software & rebooting fixes the problem --for about a day.

press button on all three devices. the light blinks on kbd and mouse. then go ahead and do the add device. It should do.

This is sort of general but it just may help.
Make sure your batteries are in correctly.
Make sure the transmitter dongle is in the USB.
Look on the transmitter and the mouse and keyboard
itself (bottom) for a little tiny button that says connect
or reconnect. Move the mouse about six inches away from
the transmitter and press both the transmitter and the mouse.
That should reestablish the signal twixt the two.(or three KB)

If you're lucky, the coffee did not penetrate into the key membranes. Remove the battery, then try rinsing the affected area with clean water the same way you spilled your coffee. That way the water will go into the same areas. If you try some upside-down-on-an-angle rinse, the water may not get into the sticky areas. Dry immediately using a hair dryer set on low/medium.

Chances are it's ruined, but a few minutes of rinsing and drying might save your keyboard. Not much to lose by trying.

try re syncing it to the base, press and hold the button on the base at the same time you press it on the keyboard and hold for about 15 seconds, then repeat but with the mouse this time

you need to install the software that came with your mouse or find it on Microsoft website:
