Was it a whining sound? First guess would be spike in power consumption and the inductors making noise in the power supply.
- karmakaze 8y agoIt wasn't like a transformer whine, more of like a white/pink noise 'sheeh' sound that would sound once when there was a large amount of video memory updated e.g. full graphic screen clear especially on high res/colour modes.
- zamalek 8y agoI remember that from certain phix modes (a TSR VGA emulator for Hercules/monochrome systems). Other modes would cause a consistent audible whistle to come from the CRT. But hey, at least I could play raster games.
- gh02t 8y agoNowadays, certain games make the GPU in my desktop whine, though I'm pretty sure it's some kind of coil whine in my case. It's equally mysterious however, it's only certain games. And it's not load-based, some relatively lightweight games do it and sometimes it's heavier games. Only a few do it, too.
