I've got a SyncMaster 932BW that is jittery, and then blinks to black, and then back on. This saga started when all of a sudden, horizontal squiggly lines appeared on my display. I rebooted, and then I came up with a few sets of 5, or so, red vertical lines. Again I rebooted, and low and behold, my screen resolution went from 1280 x 768 to about 800 x 600. This made me believe that my GeForce 8800 was about to die, so I went out and bought a Geforce 210. Now the screen has a horizontal jitter, and then goes to black at random times, sometimes only once and sometimes about 5 times in 30 seconds. I'm at a loss at what to try next. Any suggestions would be greatly appreciated.
