Hi Raj--
In case this not part of the new "Shake your booty" initative from Redmond
to augment the way over hyped Aero Glass (or the Redmond initiative to sell
a helluva lot more hdw for their partners), II'd approach the shaking windoz
syndrome this way:
I wonder if this has happened since the moment you loaded Vista with IE7 or
ever before on that machine. Most probably by setting your display
correctly, this will resolve. In particular make sure that you have the
most optimal screen resolution and especially the *refresh rate for your
particular monitor.
These are usually found by rt. clicking the desktop>personalize>Display
settings>Advanced settings button (lower right of the Display Settings
dialogue box>from there the tabs and layout are going to depend on your
particular Video card. For Nvidia or ATI there should be a monitor tab and
the refresh rate is set there. For some video cards the setting is already
default chosen for you.
Sometimes there is a troubleshooting tab with another dialogue box. If you
have an Nvidia or ATI card, you usually also get more tweaks with a control
panel.
See this link and in particular the paragraph on resolving monitor flicker
but I realize shaking is different from flickering:

Often reasons for the window shaking are offered that are rarer causes like:
Electro Magnetic Interference (EMI) may cause interference with electrical
equipment like monitors Cellphones, TV's, radios etc. 'cause abnormal
frequencies that your monitor may shudder from. Keep these devices away from
the monitor.
In the Bios* you may find settings for CPU voltage etc. that let you
increase the tolerance for EMI by a small percentage. This should be enough
to stop the monitor screen from shaking so much if the shake is being caused
by EMI from within the computer itself.
Sometimes, increasing the clock spread spectrum to .75% will stop shaking.
Spread Spectrum
When the motherboard's clock generator pulses, the extreme values (spikes)
of the pulses creates EMI (Electromagnetic Interference). The Spread
Spectrum function reduces the EMI generated by modulating the pulses so that
the spikes of the pulses are reduced to flatter curves. If you do not have
any EMI problem, leave the setting at 'disabled' for optimal system
stability and performance. But if you are plagued by EMI, change the setting
to 'enabled' for EMI reduction. Remember to disable Spread Spectrum if you
are overclocking because even a slight jitter can introduce a temporary
boost in clockspeed which may just cause your overclocked processor to lock
up.
