I have an HP Pavilion desktop computer that is about 4 yrs. old and am running XP with SP3. I recently upgraded the drivers for my Diamond Radeon X1050 video card. I have a flat panel screen (I think it's an Acer - inherited it from my mother) - model no. is L17NCDT if that helps.
While working in a particular application like Word or Excel, or playing a game, all of a sudden the monitor goes blank and shows either "No Sync" or "Signal Out of Range." Since I can't see anything when this happens, I have to manually turn the computer off and then back on.
Any ideas why this is happening and what I can do to fix this? It gets really irritating since I work from home and may have several windows open at once, then I have to start all over again.
Thanks!
