NOD32 problems

Hello to all,
I just installed NOd32 into my computer and used to work fine until i turned off my computer. Everytime I turn off my computer I receive a message stating that Drive A is not ready to close...but I do not have a drive A. TO solve this I unchecked the diskette option in Amon settings but I still get this message.

One more thing, for some reason it crashes for no reason at all and the screen turns black. After restarting my computer several times I noticed my usb stick was still connected, I disconnected it and my computer magically turned on. My usb drive is essential, any ideas on how i can fix these problems?

For the "Drive A" problem, try looking in your computer's BIOS setup for an option to disable the Floppy Controller or to change "Drive A" to "None". The BIOS may also have other settings that have to do with the Floppy and/or Drive A. Try playing around with those.

For the USB problem.... hmmm.... I am not sure. Could the computer be trying to boot to the USB stick for some strange reason? Double-check the Boot Order settings in your BIOS. I am not sure why it would cause a problem now and not before, though.
