Flat Panel Lcd Jitter/Shakes..........?

Question

I have a flat panel 17' viewable monitor in which the screen has been shaking/jittering in a side to side motion since installing Vista Premium to a partitioned hard-drive. I also have XP Pro on a different partition and I get none of this when it's in use.

The screen seems to stabilize in Vista as long as I am not moving the mouse to open a window, start a program, etc. I noticed also that Vista set my screen resolution to max (1280x1024) with the refresh rate at 60hz. In XP it's set at 1024x768 (60hz). I adjusted the setting somewhat in Vista to see if this would improve things, but the shakes/jitters are still there. I really don't know much about refresh rates and these monitor settings, or what ever it could be that's making this happen suddenly, so I hoping that someone here could advise on what to do.

My computer is a AMD 64x2, 2.2 ghz processor with 1gig of installed ram, and my graphics card is an Nvidia Gforce 6100, built into the motherboard utilizing 256megs of ram.

Thanks, any help would be appreciated. :)

@ D McC

Yeah, I'm thinking that could be one possible reason. It might be that I haven't done any updates yet also, maybe some driver needs updating. The Advisory tool didn't reveal any problems with my video card, or, amount of installed ram. All of the key components got green lights.

Answer 1

you may need a seperate graphics card with dedicated memory instead of using shared memory. ms reccomend a gig of memory and separate graphics memory, you could try more ram first before you buy a graphics card

Answer 2

I would install a separate display adapter (like an EVGA eGeForce 7100GS, they're relatively inexpensive but can handle Vista) and see if that clears it up - my guess is that sharing the memory with the onboard display adapter isn't working well in Vista.
