My friend just got a hand me down g3 tower that was working fine, but when he moved it to his house the display was all green. I am guessing the viedo card got loose in transit, but, I am not too familiar with these newer form factors. What does it uusally mean, and how to fix it?
1) It's probably not that the card is loose, but that the cable is loose, either at the card, or on the monitor. Check the connection at the card, and the pins there to make none are pushed in, bent or broken.
2) It could be broken cable, or an intermittently broken cable.
3) It could also eiother be a dying monitor or a dying card, but the most likely cause of 'all green' is a failed or failing cable, either the actual cable or the connections.
Fixing it will depend on the monitor. If it has a cable detachable at both ends, this is a cheap fix, $5-$10 at a decent electronics supply store. If the cable is permanently attached to the monitor, then it calls for surgery on the monitor with all the attendant caveats about working with CRTs that can kill you for hours or days after the thing's been unplugged.
Quickest check is to try a different monitor, though I've been fooled more than once by stubbornly hard to connect cables, especially when the computer isn't on the bench, but is under someone's desk.
