For the past 6th months i've been using an old radeon 9200 in my machine but for some reason the dvi output has stopped working. Last night it was working fine with no problems but today it has just stopped working. The vga works fine.

When i turn on my computer with the dvi plugged in, my monitor does the usual and goes from amber to green but the screen remains blank.

This is not terribly urgent but i would like it fixed as its just one of those annoying worries i could do without.
thanks
Matt
