Hello, i was having a 24hz issue with my 40" Samsung TV and i decided to buy a new TV since i needed a big TV at my living room, so i ended up choosing a Sony 32" TV with 3D, when i tried to use the computer with both of my cards on crossfire with the main one on the first PCI-E slot, but it still gave me pixels on my screen along with the 24hz problem, i took the main card out and put the HDMI cable on the second one alone and it worked, but i still have a few red pixels on my screen, and also now when i try to turn my PS3 on it gives me no signal, it worked fine until i tried to turn the PC on.

Samsung TV is a Series 5 550

Sony TV is a Bravia KDL-32HX755

My VGAs are two AMD Radeon 6870 with crossfire

My motherboard is a ASRock Deluxe5

The red dots stopped somehow, i uninstalled catalyst and then installed it with my 20 GPUs on crossfire and it worked, but then when i touched the HDMI cable it started again, that is when i realized what the problem was, the HDMI cable wasn't being able to hold it's own weight so it wasn't properly connected and that caused the red dots, any tips on making the hdmi cable stay still, my TV gets some 1 screen second black flicker from time to time and i believe that is the cause of the cable so i need to get it straght.
