Sometimes, when rebooting the machine because of an install, for example,
the windows xp logo will appear and then the screen is set to some
resolution that causes it to flash (vertical lines go across the screen) and
the monitor puts up a dialog box, 'not in optimal mode'. The native
resolution for my lcd is 1600x1200 and the 'not optimal mode' dialog is part
of the monitor.

The wallpaper for the desktop appears and then the not optimal mode dialog.
Usually hitting the reset button and letting it boot a second time fixes it
but sometimes, it takes a 3rd reboot.

Has anyone seen this? I left my bios at the defaults and smartgart shows
the defaults are fine although smartgart never kickes in. My hardware is:

amd athlon 3200
VisionTek Radeon 9250
Asus A8V MB
2 WD EIDE Hard Drives

I also turned on agp calibration cycle and dbi but was able to get it to
happen again by rebooting a several times.

I checked the lcd monitor's dialog box closely and it says, 'not optimal
mode, recommended mode 1600x1200'. I usually reset the machine fairly
quickly because of the vertical lines walking across the screen. The
desktop wallpaper occupies about half the screen, so, I figure the vudeo
card is setting the monitor at a higher resolution than it can handle.

It also appears that smartgart and vpu recovery feel all is ok because
nothing appears except the desktop and the normal icons.

Are you using the VGA port or the DVI-I port on the video card?

I would recomend using the DVI port on the video card with a DVI cable to
the DVI port on the LCD panel, if it has one.
 
I changed the bios to 'plug and play os' = yes.

After about 10 reboots, the problem has not occurred. Maybe that fixed it
(knocking on wood).
