I had this exact problem. What worked for me is to go the "Device Manager" and click on the "Human Interface Devices" tab. If you have something called "Microsoft eHome Infrared Transceiver," uninstall it by right clicking. It worked for me. Apparently the transceiver affects the tilde key. Hope it helps.

I'm not really sure what to say if you're still having problems. FO3 had resolution problems with the console not be3ing visible. MAybe try increasing the resolution if you can. Other than that, I don't know.
