I got this graphics card in my PC and the picture on the monitor
displays red dots and lines and sometimes goes away but returns
again. I had to disable the driver for this card as Windows XP wont
boot in normal mode ie shows a black screen but in safe mode XP boots
but with red spots and lines and the picture goes purple if you try to
browse on the internet. Is there any tests I can do with a
multimeter? Or maybe get hold of a circuit diagram?
