Sounds like you have a problem you need to fix immediately. Let me rephrase that: a problem you need to have someone fix. I'd guess a defective PC power supply, especially if you can get sparks just plugging the monitor into the PC. If not that, it could be a defective ground on the outlet you're usign for the PC, a miswired outlet, a defective power cord or something. If you don't know *FOR SURE* exacgly what to do to troubleshoot and fix this problem, please find someone who does. You definitely do not want to teach yourself AC electrical theory on live household circuits. Dale --- We are Dyslexia of Borg. Fusistance is retile.
