Or it's possible your tube is about to burn out. Best run screaming, when it goes it's likely to explode and send splintering glass shrapnel into your EYES.
Or, you know, just start looking for another monitor.
But if it starts making buzzing noises, get under your desk as quickly as possible. I'm just saying.
great advice. you know, I think i'll just play games from under my desk and have a series of mirrors set up underneath so I can see the monitor without risking glass shrapnel in my eyes.
oh yeah, degauss works... but only for a while. but hey, ti's more effective than turning my monitor off and on again.
