Hello,
I've recently purchased an HD5770 off of ebay that had had a more efficient cooling solution applied (background). I've had a 5770 for a couple years already, and not had any problems with it, but decided i wanted to try crossfire because i'd heard that the performance of 5770s in crossfire is excellent.
The problem
If i have it as the only video card, the computer will boot and fans spin (etc.), but my monitor displays only "No signal" before going into sleep mode. If i have it in crossfire and the dvi/vga/hdmi cable (tried all three) is plugged into the new card, the same thing happens. If i have the dvi/vga cable plugged into the old card the same thing happens, but if the hdmi cable is plugged into the old card, the monitor behaves normally. The computer will boot, i can get into the BIOS, and it will show the Win 7 loading screen before it boots completely into Windows, but will freeze just a second before it boots completely.
Is there anything i can do? The seller said the card was working when he sent it. It crossed international lines (Canada-->U.S.), but the packaging was excellent (anti-static bag, foam peanuts, etc.)
Thank you in advance, kind people who know things about computers.
I posted this previously on overclock.net forums, and the advice i received didnt prove helpful (was recommended to completely wipe the AMD graphics drivers, then reinstall them; did it a couple times to be sure, but with no luck).
