I recently purchased a Logitech wireless keyboard/mouse set. I installed everything and it worked fine. I installed the driver, and all was good. I decided to uninstall the driver, and I restarted the computer. Everything starts up fine, but there is no cursor! The keyboard also has no effect! I'm typing all this on my slave giga machine as I can't fix my main machine.
Install the driver with the keyboard and mouse from your Giga computer. If the cursor doesn't come up even with a normal mouse try installing the driver in Windows Safe Mode (press F8 after BIOS checks on startup). You might get the cursor there.
