I have a GTI Club driving game with the force feedback electric steering. Whenever the electric motor kicks in the screen scrambles on the monitor. I have converted the game to a LCD screen and tested 2 different monitors. The game plays and displays fine if I disconnect the motor after the game boots. Any ideas on how to fix the issue?

where are you getting the power for lcd from?
do you have ferrite shields on the vga leads,motor power,how are converting the 25k signal to 31k-where are you getting the power to supply a converter if using one

I am using a converter board which is being powered by a hacked computer power supply.

Force feedback uses a big motor to knock the steering wheel from your hand. Resulting are a big spike on the power supply, and a strong magnetic field as the motor ramps up. Both can really interfere with your lcd.
Step 1: Play with the position and shielding type of your vga cable to see if there is any magnetic coupling ruining the high bandwith VGA signal.
Step 2: Check the power supply. As you are using a seperate computer supply, the spike could come through the ground line.
The vga cable interference possibility is most likely, though.
