every time I boot it, after it already loaded the desktop and is loading the auto-start programs, it'll breifly flash a black screen, just before starting the network, which is usually the last thing to load.
I had this problem once, and the culprit was the NVidia Graphics Card Driver.
I did some "bad configuration" (change 'Coolbits' settings) and the "black screen" blinks every time that I turned on the PC.
Take a look at your video card driver.
Good luck,
Anderton.
No it wasn't bad configuration. NVidia (and other manufacturers') graphics drivers add themselves to desktop context menu (in order to be 'readilly accessible on right click' - I call it 'in your face'). Depending on the version of the driver and actual hardware, it might be or not be visible.
To cure it, use another Sysinternals tool - Autoruns.
Look in the following location:
CODE
REGEDIT 4
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Directory\Background\shellex\ContextMenuHandlers\New]
@="{D969A300-E7FF-11d0-A93B-00A0C90F2719}"
This is the built-in windows entry that must remain! NVidia adds two entries at the same level named 00Nview and (another one). I don't have the exact names because on my computers they are long gone.

Deleting them should get rid of the blinking.
For good measure, other NVidia's startup entries could be deleted (Under HKLM/HKCU...Run key), and their service could be disabled, because I haven't found any proof they are of any use except for returning themselves in startup. But that's up to personal taste... or should I say belief in good will of Nvidia's programmers?
