here's my problem....when i start up my computer, i get all kinds of vertical lines in a pattern across te screen, like right now on that computer its sitting at the LILO bootloader and there are 1/2 inch wide lines running vertically that are made up of lots of different colors, when i boot into windows i cant even log in and the monitor just shuts off and the computer restarts after a while. i tried cleaning it and everything is clean and i put new thermal paste on the cpu and graphics card, cpu heat shouldn't be a problem at all, because my temp usually runs about 31C. there used to be like little dots of color in random places but now it has gotten much worse, i've tried different drivers and that does nothing.....anyone have any ideas?
