No video

I've got a new PC with a fresh install of Windows 7 Pro, 64-bit.  The PC 
boots, windows starts, and then the monitor says that there is no signal 
and goes to sleep.  The hard drive light flashes occasionally like it's 
waiting for a log in but I can't tell.  If I boot into safe mode or the 
last working startup then it displays fine.  This first started when I 
loaded the chipset and other drivers following the Windows install.  I 
reverted to the last working startup, loaded the drivers individually, and 
it was OK.  I rebooted and it was still OK.  I ran Windows Update and it 
lost the video signal again.  I reverted to the last working startup and 
it was OK.  I let my wife use it to get on the Internet and a day later 
she said that it was doing it again.

It's a DVI video output on the motherboard with no VGA, although the 
monitor supports both.  I do have a decent DVI card that I could stick in 
it but I would prefer to get it working as is.  Ideas?
