I have a P4 Asus mobo with a Rad AIW 9700 video card and a NEC 1760NX monitor. Everything worked wornderfully until I recently upgraded the Windows SP2. Starting the very next day I had trouble with the video signal being interrupted. The screen just suddenly goes blank - no signal. There is no pattern to it. It seems to happen more likely and frequently during the first hour of the computer being turned on. It does not seem to happen with relation any particular program. I've searched the ATI website and looked online for any known issues and come up blank. Anyone here have a suggestion?
