HD4870x2 and LCD TV Prob

I got a big problem with my sapphire HD4870x2. I got a new Philips 42PFL7404hH/12 LCD TV and I have my computer connected with a HDMI cable. The resolution is 1920x1080 running at 60Hz. Now the problem is that every few minutes the screen will go black for a second then it will be ok, also sometime when the display comes back-on all the colours will be mixed up like someone changed the spectrum. I tried my PS3 on the TV and I do not get this problem also I reinstalled my vista 64 and all was fine with my display until I installed CCC and the drivers (of course I was not getting any amazing graphics on the windows drivers).
Now I have tried every configuration on CCC. Does anyone have any idea what it might be?

My computer is a Gigabyte GA-EX58-UD5 motherboard, Coolermaster Real Power M1000 1000w PSU, Core i7 920 CPU and 12Gb or RAM.

Check the event viewer invista for anything at the same time as the going black.

Could be the dispaly drvier stops responding. Could be something wrong with the hotswap detection in the card/port that makes the monitor show up as new repeatedly, which could be something as simple as a not snug enough cable.
