What causes monitors to get wobbly wiggly screens?

the only times i've come across such was when my power supply was dying, or using compiz.

Yes, both computers have their own desktop speakers next to the monitors, and the one I use now has a small subwoofer on the floor. This has given me some ideas to try some rearranging.

The PC speakers would have magnetic shielding to prevent such a thing. I know that having a cordless phone base, or a cellular phone near the computer will cause problems like this also.

Your monitor is magnetically charged. It takes a while to wear off... Unless you hit the degauss button. That resets the monitor, so it should be fixed. LCDs and other things don't have that problem, however.

The problem could be a defective filter capacitor in the power supply. There are several possibilities including defective connections on the main circuit board. Lcd monitors are so cheap now I wouldn't spend a lot of money on having them repaired. Good luck.
