Monitor not in device manager, vertical lines on display

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!
