I've seen that "flicker" a couple times; it's so fast that the first time you aren't sure it even happened. All said this might even justify even more the ext. warranty as I plan to keep mine for 2 - 2/12 years.
I too have had the rare flicker and also wasn't sure I wasn't just seeing things. You won't believe what I "think" it is. MSMSGS.EXE. Yup, good old Microsoft Instant Messaging. I could well be wrong, and no doubt a bunch of you will swear that it ain't it, and fine, but THOROUGHLY getting rid of it seems to have solved the flicker, for the time being at least.
I kept seeing this flash, so I watched various CPU graphs, and the process list in Task Manager (sorted by CPU usage (click twice on the CPU column)), and could see spikes every time it flashed. I couldn't see any errors in any of the Event Viewers, and couldn't catch the process that spiked (should have highlighted msmsgs.exe, for awhile I thought it was iexplore).
I went throught several of the usual routines to remove IM (MSConfig, unhide it via the Registry, remove it from Add\Remove, Windows Components, etc.) but it still kept appearing in the Process List even though it was no longer in the SysTray. I think Outlook Express I use may have been insistant in keeping it. Even after uninstall I still had a full C:\Program Files\Messenger folder. Finally I killed the process and renamed the folder. Msmsgs has gone away and so has my flashing.
Mayyybe it's a coincidence, as IM is used on bazillions of PCs, but it seems to have worked for me. If anyone knows how to log thread activity you might also be able to record those spikes. Good luck!
