my Dell Dimension 8300 -lrb- over 5 year old -rrb- start have video problem . I read one of the other review on the Amazon site , and that customer have a similar problem with a similar computer . I have already plug in a different monitor and have the same problem , so I rule out it be the monitor . next bext guess , it be either the video card or the motherboard . Video card $ 50 or motherboard ... probably would have go with a new computer . long story short , the card work like a charm , and I be back in business .
