Hardware/Software
. new SONY VAIO VPCYB33KX/B notebook with Win7/SP1 32bit
. AMD Radeon HD 6320 series graphics
post-doc: atieclxx.exe's TOD was: 06/30/2011 22:10 ver 8.861.0.0
new TOD is: 04/05/2012 20:16 ver 8.961.0.0

Known good Hardware/Software
. existing HP notebook with Win7 32bit
. different display adapter

Symptoms
. constant but sporatic (from a few seconds to an hour), temporary (a few seconds) "black screen", either when just sitting there idle, or working, using an external VGA monitor with a KVM available (but NOT manually switched during these periods) to switch it among notebooks. This problem does NOT, and has NEVER, occured randomly on the existing notebook. Every time this happens, the REMOVE.wav sound is played, as if a device on a USB port was removed/installed (the KVM uses a USB port along with the VGA port; tried in all 3 USB ports), tho EVEN THIS is VERY HARD TO HEAR (hopefully, the last problem!). This symptom is similar to when I use CP/Display/adjust resolution when temporarily going from 800x600 to 1024x768. Worse, even tho I set up the machine's display as "full screen" (via AMD ECC), when I used the KVM to switch machines, when left on the other machine, the new notebook's display was shrunk horizontally, as if it decided to go
to "preserve aspect ratio"; yet, when I switched back, after the black screen, it would go back to "full screen".

. this would even occur before logging on to Windows, and even under the Admin logonid.

Available:

. in EventViewer, 6 exact-same entries for each black screen occurance:

Attempts to stop:
. WAY TOO MANY TO LIST (at least 36!); EVERY SINGLE ONE USELESS!!!
. services.msc; temp stopped 'AMD External Events Utility'
. used CP/Device Manager to check/update/search online for drivers
. display
. monitor
BOTH SAID THEY HAVE THE "best" drivers!
. since CCC.exe was in the event logs, I temp replaced it w/my own MASM program (which basically just returns back to the OS, a la IEFBR14 (in IBM mainframe-speak)).
Tho, after re-boot, CCC.exe was no longer in TaskManager as a running process, the problem still occured, so CCC.exe per se could not be the cause; it was just a victim.

Solution
As for the COURE.fon problem, I could AGAIN say everything that I tried & failed, but the bottom line is that the clues seemed to point to the Video Display Adapter.
After backing up my system, I decided to use a sledgehammer and use the AMD ECC to 'auto-detect and install' what it found as a new available video driver:
12-4_vista_win7_32_dd_ccc.exe
which was different than what was available manually and generically from the same URL:
12-3_vista_win7_32_dd_ccc.exe
so I installed the former and re-booted, set up my traces, and waited...after 2 days, this problem now no longer occurs!! FINALLY! Even better, when I switch btx the machines using the KVM, NO LONGER DOES ANY BLACK SCREEN OCCUR!!! And no more of those entries in EventViewer.
It's strange that, for such an ANNOYING PROBLEM, there is nothing in 'VAIO Update' (similar in function to 'Windows Update') to address and fix this automatically.
Since this is a new machine with a very small screen, many people may use an external VGA. If so, and you are having black screen issues, try doing what I had to do. Good luck.
