Yeah, I had a 5670 already in my computer so I bought another 5670 just to not waste the already existing one. I plugged the other one in, connected the PCI-e cables, and turned the PC on. It started(though it did the "fan speedup" thing twice before beeping), it went to the "Starting Windows" screen and BOOM! black screen. And my monitor doesn't say "no signal", it's literally a black screen. Here's a list of things I've tried:
1. Uninstall drivers, use Driver Sweeper and ATIMan Uninstaller combined, installed drivers again - no success.
2. Swap cards - no success.
3. Use system repair - no success.
4. Fiddle with every possible motherboard BIOS setting - no success.
5. Update motherboard BIOS - no success.
6. Deconnect the PCI-e power connector from the second card before starting up and connect the power connector after Windows load up(yeah I know it's crazy) - partial success, it boots but it doesn't detect the second card
7. sfc /scannow - no success.
Here's my system specs:
Gigabyte GA-970A-D3
AMD Phenom II x6 1100T Black Edition
OCZ Vertex 3 60GB
PowerColor HD5670x2 2GB
Corsair 2x4GB 1600MHz DDR3
I'm using Windows 7 Ultimate.
