I found out the hard way that if I update my video drivers via Micrsoft Update, my desktop completly dissapears on re-boot and I get a yellow screen.It's pretty bad whenMicrosofts own drivers don't work! I have found only 2 drivers that work ANDgive me video out. One is 165.25_omega_beta.exe a driver that was tweeked for gameing and 100.65.winvista_32bit_international.exe. 100.65 is the one I use most all the time now. Hope this helps someone........or at least supplies a small grin.:)
