noticed entire display was vibrating

[eknirb]

I've been leaving PC on overnight periodically, uploading my iTunes collection to the new Google Music beta online storage.

I come in this morning- the program had finally finished- over 6400 songs- and I noticed that the screen was vibrating. It does about 500 a night or so.

the 'Google' logo on the web page. Even the icons in the systray. Back and forth. very subtlety.

A reboot, and it's gone.

Was it fast? slow?

Did you maybe turn the monitor off while the computer was on all night?

Or maybe the monitor got auto power disabled duringthe night?

If so then the video card may have switch to a different timing mode and did not switch back properly when the monitor came back on...

Yeah it just sounds like a power management feature went bonkers.
You could try disabling the power saving features the next night you leave it on.

Outside of that I would just make sure cables and plugs are all fully secure.
Vibration isn't a common sign of a graphics card problem, generally they begin displaying brightly colored dots we call artifacts when they start going bad.
fseal's explanation also makes sense, though that would be strange as well.

very curious. nothing changed. new PC, 2 weeks old. it was just a very fuzzy vibration. Not BACK and FORTH LEFT AND RIGHT...just everything was fidgeting back and forth. Never seen that, ever.
