Here I have three large red vertical lines at boot time and "pollution" in the form of a multitude of small horizontal lines. When XP is loaded, it turns into a multidimensional red square. After having set the resolution everything was OK, but after 5 to 6 minutes return lines and red squares. I connected a VGA screen but got the same defects. Loading new drivers for GC but nothing works and then back to former. I have also updated the BIOS but no improvement. I have tried many things but no picture can be seen on the LCD screen.
