I have two PCs and a radio in my office. One of the PCs (my new one) causes terrible static on the AM band. The guy who built the computer for me says this is normal, but the older computer doesn't cause static. Any suggestions on how to fix this?
Make absolutely sure your case cover and all panels are firmly connected together. Make sure your power cords are all grounded/earthed. You may need things called "ferrite cores" on your video cable. Move any antennas as far as possible away from the PCs. Also make sure any shielding is firmly screwed in place.
