I have the same problem, and I doubt it's because the power supply. I
have a 400 W PSU, GF FX5600XT AGP graphics card, and Athlon 64 3500+
CPU. The lines appear only on TV, which is connected to my PC via
VGA->SCART adapter cable. Do I need to modify the xorg.conf modeline?
Any help is greatly appreciated.
