The video card in this system is ATI Radeon HD 5570 and the driver version is 8.8.21. It works just fine; however, the driver is spamming the event log with informational messages like these:

At this forum, this is how these logs explained, quote:
And again, in my other system with the Asus P7P55 motherboard, with ATI Radeon HD 5850 video card, drive version 8.801.0, there are no event ID 62464 informational messages. I am not certain that the driver version would make that much difference.
The major difference between the two system is the OS. The machine with these event ID messages is Windows 7 64-bit with SP1, while the other is the same without the SP1. I vaguely can recall some discussion about SP1 adding High-bandwidth Digital Content Protection (HDCP), which can contribute to some of the issues I've experienced with this new PC. If the HDCP had been added, is there a way to remove it from the system? Well, short of starting fresh and don't add SP1.
Thanks in advance....
