Any other suggestions folks? I have upgraded to the 10.11 version of the Catalyst software and there has been no improvement to the situation. By the ways the PC has 64bit Windows 7, 430W Antec Earthwatts PSU, and 4GB memory.
The same problem has just occured with my HDTV Samsung. Did you ever find out a reason for it. My TV comes on for about 2 seconds and then all I get is sound I get the same message in the top left hand corner (No Time Information).
Please let me know what the solution was. I appreciate it.
