I'm writing about some intermittent black screens I'm encountering with a new computer I just got. The specs are:
DFI NF4 Ultra D motherboard
Athlon 64 X2 3800+
EVGA 6800GS
OCZ 2x512 DDR400
Windows XP /w SP2
It seems I'm getting them whenever I do something that requires a refresh of some graphical elements. ex. click on a link that displays a new window, dragging the scrollbar of a window up and down. The screen gets momentarily frozen then a black screen appears for about a second. Another example: The file copy folder animation can cause the black screen to appear several times. Sometimes when bringing back a minimized window, its contents are not shown - only the title bar and window frame.
Interestingly this seems to only affect windows navigation - this does not happen in any games.
I tried the latest Nvidia drivers, the latest EVGA driver, and the EVGA drivers on the CD - same thing. Rarely and randomly small parts of the screen get garbled too. Refreshing the garbled area gets rid of it. Note that with the basic Windows VGA drivers the problem did not occur.
FWIW I also got a BSOD when installing Windows and couple of program crashes when installing Visual Studio 2005 and a Windows security update. None reoccured when I tried again.
Mobo BIOS date is 06/23/05 which appears to be up to date.
thanks for any help
