Hi guys, I've asked for help on this forum before and it's always proved great so here goes again. I've had two HD5850's running in crossfire for over a year now, but this morning I updated my GPU drivers, and was confused to see that the CrossfireX tab was gone from CCC. Upon checking in device manager I saw that only one card was showing up, so I ripped out the main card and just left the secondary card plugged in. With speakers on the screen was blank, and after a 'normal' amount of time, windows made the chime, but my monitor was still reporting no signal. So is my card borked? Running a single card is fine for now, but want to see if I can work out if my secondary card is damaged before I rip it apart and add it to my collection of 'ex-video-cards.' Any thoughts? Thanks, Ruu.
