I notice appreciable flicker at 60Hz. Electromagnetic interference from other sources is a possibility, and the power line you mention could be a source, though I would be a little surprised. If it is electromagnetic interference, you should be able to pick it up as static on a radio, and it should be affecting other devices like a TV. In that case, you could try moving the location of the computer to see if it makes a difference. Shielding is a possibility, but problematic with a CRT that puts out a lot of heat. For refresh rate issues, you could try updating the driver, or using a different one. Most monitors, and graphics controllers, even on-board ones, should be able to do 1024x768 at better than 60Hz. Look up the specifications for yours. The other alternative, of course, is to buy a dedicated graphics card, but first check your monitor specifications.
