I have a new win xp home pc with a 4+ year old CRT monitor. As of the last couple days, the monitor will begin flashing unreadably after about 10 minutes of use until I put it in standby mode for a couple minutes. However, it won't stay in standby mode more than 10 minutes or so...I'm running NAV and firewall and something always seems to pop up - I've turned off live update, which gets me up to about 10 minutes. Now that I think back on it, I've heard the monitor turning on and off quite frequently, and am trying to figure out it that's something to do with my flickering/flashing. Any ideas how I can get my monitor back? And what about standby? Can I keep the thing in standby, or do I need to give it up? I currently have it set to go into standby after 15 minutes, although I usually manually put it on when I leave. The monitor worked fine for the first couple weeks of use with this box, and worked fine for the last four years with W2K.
