Monitor not in device manager, vertical lines on display

[rt]

HP Pavilion ZV5400 laptop
XP SP2
Nvidia GeForce4 440 Go 64M integrated graphics

The problem started when coming out of screensaver mode. The
desktop icons didn't look right. When I clicked one of them the
screen started blinking. I shut down by pressing the power
button for 5 seconds. When rebooted the LCD screen shows thin
vertical lines across it spaced about 1/4 inch apart and the PC
crashes when it gets to the desktop. I tried enabling VGA mode,
but it still crashes. It will only boot in safe mode, but it
still has the vertical lines. I uninstalled and reinstalled the
display drivers. Also noticed there is no monitor listed in
device manager. In display
properties/settings/advanced/monitor,
it says default monitor is being used. Could a problem with the
video card cause the monitor to not show up in device manager?

As it is a laptop there is little you can do. Backup your data and send the
machine back to HP for repair.

Thanks, but It's out of warranty. Ive been watching for a
motherboard on eBay using "favorite search". Coincidentally a
non-working board is up for auction with the same problem. It
was pulled from a laptop that had vertical lines on the screen.
A working board was listed a few days ago with "buy it
now",which I acted on as soon as I received notice it was
listed, but it was gone in a nanosecond!
